| 1 | Precise nanomedicine for intelligent therapy of cancer显示文摘Precise nanomedicine has been extensively explored for efficient cancer imaging and targeted cancer therapy, as evidenced by a few breakthroughs in their preclinical and clinical explorations. Here, we demonstrate the recent advances of intelligent cancer nanomedicine, and discuss the comprehensive understanding of their structure-function relationship for smart and efficient cancer nanomedicine including various imaging and therapeutic applications, as well as nanotoxicity. In particular, a few emerging strategies that have advanced cancer nanomedicine are also highlighted as the emerging focus such as tumor imprisonment, supramolecular chemotherapy, and DNA nanorobot. The challenge and outlook of some scientific and engineering issues are also discussed in future development. We wish to highlight these new progress of precise nanomedicine with the ultimate goal to inspire more successful explorations of intelligent nanoparticles for future clinical translations. | Huabing Chen Zhanjun Gu Hongwei An Chunying Chen Jie Chen Ran Cui Siqin Chen Weihai Chen Xuesi Chen Xiaoyuan Chen Zhuo Chen Baoquan Ding Qian Dong Qin Fan Ting Fu Dayong Hou Qiao Jiang Hengte Ke Xiqun Jiang Gang Liu Suping Li Tianyu Li Zhuang Liu Guangjun Nie Muhammad Ovais Daiwen Pang Nasha Qiu Youqing Shen Huayu Tian Chao Wang Hao Wang Ziqi Wang Huaping Xu Jiang-Fei Xu Xiangliang Yang Shuang Zhu Xianchuang Zheng Xianzheng Zhang Yanbing Zhao Weihong Tan Xi Zhang Yuliang Zhao | 2018 | Science China Chemistry2018，61，12： | 19 |
| 2 | Scattering of SH waves induced by a symmetrical V-shaped canyon: a unified analytical solution显示文摘This paper reports a series solution of wave functions for two-dimensional scattering and diffraction of plane SH waves induced by a symmetrical V-shaped canyon with different shape ratios. A half-space with a symmetrical V-shaped canyon is divided into two sub-regions by using a circular-arc auxiliary boundary. The two sub-regions are represented by global and local cylindrical coordinate systems, respectively. In each coordinate system, the wave field satisfying the Helmholtz equation is represented by the separation of variables method, in terms of the series of both Bessel functions and Hankel functions with unknown complex coefficients. Then, the two wave fields are described in the local coordinate system using the Graf addition theorem. Finally, the unknown coefficients are sought by satisfying the continuity conditions of the auxiliary boundary. To consider the phase characteristics of the wave scattering, a parametric analysis is carried out in the time domain by assuming an incident signal of the Ricker type. Surface and subsurface transient responses demonstrate the characteristics and mechanisms of wave propagating and scattering. | Zhang Ning Gao Yufeng Li Dayong Wu Yongxin Zhang Fei | 2012 | Earthquake Engineering and Engineering Vibration2012，11，4： | 19 |

| 4 | Crustal stress field in Yunnan: implication for crust-mantle coupling显示文摘We applied the g CAP algorithm to determine239 focal mechanism solutions 3:0 M We 6:0T with records of dense Chin Array stations deployed in Yunnan,and then inverted 686 focal mechanisms(including 447 previous results) for the regional crustal stress field with a damped linear inversion. The results indicate dominantly strike-slip environment in Yunnan as both the maximum(r1) and minimum(r3) principal stress axes are sub-horizontal. We further calculated the horizontal stress orientations(i.e., maximum and minimum horizontal compressive stress axes: S H and S h, respectively) accordingly and found an abrupt change near *26°N. To the north, S H aligns NW-SE to nearly E-W while S h aligns nearly N-S. In contrast, to the south, both S H and S h rotate laterally and show dominantly fan-shaped patterns. The minimum horizontal stress(i.e., maximum strain axis) S h rotates from NW-SE to the west of Tengchong volcano gradually to nearly E-W in west Yunnan, and further toNE-SW in the South China block in the east. The crustal strain field is consistent with the upper mantle strain field indicated by shear-wave splitting observations in Yunnan but not in other regions. Therefore, the crust and upper mantle in Yunnan are coupled and suffering vertically coherent pure-shear deformation in the lithosphere. | Zhigang Xu Zhouchuan Huang Liangshu Wang Mingjie Xu Zhifeng Ding Pan Wang Ning Mi Dayong Yu Hua Li | 2016 | Earthquake Science2016，29，2： | 15 |
| 5 | Reproductive management through integration of PGD and MPS-based noninvasive prenatal screening/diagnosis for a family with GJB2-associated hearing impairment显示文摘A couple with a proband child of GJB2(encoding the gap junction protein connexin 26)-associated hearing impairment and a previous pregnancy miscarriage sought for a reproductive solution to bear a healthy child. Our study aimed to develop a customized preconception-to-neonate care trajectory to fulfill this clinical demand by integrating preimplantation genetic diagnosis(PGD), noninvasive prenatal testing(NIPT), and noninvasive prenatal diagnosis(NIPD) into the strategy. Auditory and genetic diagnosis of the proband child was carried out to identify the disease causative mutations. The couple then received in-vitro-fertilization treatment, and eight embryos were obtained for day 5 biopsy. PGD was performed by short-tandem-repeat linkage analysis and Sanger sequencing of GJB2 gene. Transfer of a GJB2 c.235del C heterozygous embryo resulted in a singleton pregnancy. At the 13 th week of gestation, genomic DNA(g DNA) from the trio family and cell-free DNA(cf DNA) from maternal plasma were obtained for assessment of fetal chromosomal aneuploidy and GJB2 mutations. NIPT and NIPD showed the absence of chromosomal aneuploidy and GJB2-associated disease in the fetus, which was later confirmed by invasive procedures and postnatal genetic/auditory diagnosis. This strategy successfully prevented the transmission of hearing impairment in the newborn, thus providing a valuable experience in reproductive management of similar cases and potentially other monogenic disorders. | XIONG WenPing WANG DaYong GAO Yuan GAO Ya WANG HongYang GUAN Jing LAN Lan YAN JunHao ZONG Liang YUAN Yuan DONG Wei HUANG SeXin WU KeLiang WANG YaoShen WANG ZhiLi PENG HongMei LU YanPing XIE LinYi ZHAO Cui WANG Li ZHANG QiuJing GAO Yun LI Na YANG Ju YIN ZiFang HAN Bing WANG Wei CHEN Zi-Jiang WANG QiuJu | 2015 | Science China(Life Sciences)2015，58，9： | 12 |
| 6 | New strategy for designing orangish-redemitting phosphor via oxygen-vacancyinduced electronic localization显示文摘Phosphor-converted white-light-emitting diodes(pc-WLED)have been extensively employed as solid-state lighting sources,which have a very important role in people’s daily lives.However,due to the scarcity of the red component,it is difficult to realize warm white light efficiently.Hence,red-emitting phosphors are urgently required for improving the illumination quality.In this work,we develop a novel orangish-red La_(4)GeO_(8):Bi^(3+) phosphor,the emission peak of which is located at 600 nm under near-ultraviolet(n-UV)light excitation.The full width at half maximum(fwhm)is 103 nm,the internal quantum efficiency(IQE)exceeds 88%,and the external quantum efficiency(EQE)is 69%.According to Rietveld refinement analysis and density functional theory(DFT)calculations,Bi^(3+) ions randomly occupy all La sites in orthorhombic La_(4)GeO_(8).Importantly,the oxygen-vacancy-induced electronic localization around the Bi3+ions is the main reason for the highly efficient orangish-red luminescence.These results provide a new perspective and insight from the local electron structure for designing inorganic phosphor materials that realize the unique luminescence performance of Bi^(3+) ions. | Yi Wei Gongcheng Xing Kang Liu Guogang Li Peipei Dang Sisi Liang Min Liu Ziyong Cheng Dayong Jin Jun Lin | 2019 | Light(Science & Applications)2019，8，1： | 12 |
| 7 | β-diversity Patterns of Plant Community in Fragmented Habitat in a Degenerated Meadow in Songnen Plain,China显示文摘A number of isolated islands of Leymus chinensis + herbosa community were investigated in fragmented habitat islands,by Braun-Blanquet field survey approach,in a degenerated meadow in the Songnen Plain,China in 2007.These islands were classified as large,medium,and small scales on the basis of the island area(100-1000m2,large island;50-100m2,middle island;10-50m2,small island).Each scale of the investigation involved eight islands.The responses of β-diversity patterns of plant taxon to the habitat fragmentation at local community and metacommunity levels were analyzed on different scales of 24 isolated islands.The results indicated that at the local community level,there were 57 species belonging to 20 families and 49 genera in large islands,49 species belonging to 16 families and 40 genera in middle islands,and 27 species belonging to eight families and 23 genera in small islands.β-diversity indexes for species,genus and family in large,middle,and small islands varied greatly,and the highest value of the indexes was not noted in the largest island.However,the average of the data obtained at the three scales showed that across large islands,Whittaker indexes were low and Bray-Curtis similarity indexes were high,while across small islands,Whittaker indexes were high and Bray-Curtis similarity indexes were low.At the metacommunity level,Whittaker indexes for species and genus showed a great significantly negative double logarithmic correlation(p<0.01) with the island area,whereas the Bray-Curtis indexes for species,genus and family showed a great significantly positive double logarithmic correlation(p<0.01) with the island area.At both local community and metacommunity levels,turnovers of species and genus could respond more sensitively to spatial changes of plant diversity patterns than that of family.Hence,the species and the genus could be used for the analysis of β-diversity patterns of plant community. | HAN Dayong LI Haiyan YANG Yunfei | 2009 | Chinese Geographical Science2009，19，4： | 11 |
| 8 | Guanling Biota: A Marker of Triassic Biotic Recovery from the end-Permian Extinction in the Ancient Guizhou Sea显示文摘After a slow recovery from the end-Permian extinction during the Early Triassic and rapid radiation in the Middle Triassic, evolution of organisms reached a new peak phase in the Late Triassic. The Guanling Biota from the Wayao Member (conodont Paragondolella polygnathiformis Zone), Falang Formation, Xinpu, Guanling County, Guizhou Province, southwestern China corresponds to this peak that marks the full recovery from the end-Permian extinction of marine ecosystems. The biota is of high diversity, containing well preserved and completely articulated skeletons of vertebrates comprising marine reptiles, fishes, and invertebrates including crinoids, ammonites, bivalves, and other fossils, and is one of the best examples of marine ecosystem records in life history. The fossil marine reptiles and crinoids are most significant in this biota, especially the marine reptiles, which provide an important link between the Triassic Pacific and Tethys, and between Triassic basal forms and the Jurassic-Cretaceous marine top predators. The most remarkable fossils are the large completely articulated ichthyosaur skeletons up to and more than 10 m, and the first recorded thalattosaurs and placodonts in China. Following our review, of the 17 named reptilian taxa the eight listed here are considered to be valid: three ichthyosaurs (Qianichthyosaurus zhoui Li, 1999; Guizhouichthyosaurus tangae Cao and Luo in Yin et al., 2000, Guanlingsaurus liangae Yin in Yin et al., 2000), three thalattosaurs (Anshunsaurus huangguoshuensis Liu, 1999, Xinpusaurus suni Yin in Yin et al., 2000, Xinpusaurus kohi Jiang et al., 2004), and two placodonts (Sinocyamodus xinpuensis Li, 2000, Psephochelys polyosteoderma Li and Rieppel, 2002). Mixosaurus guanlingensis Cao in Yin et al., 2000 might be a junior synonym of Qianichthyosaurus zhoui Li, 1999, and Cymbospondylus asiaticus Li and You, 2002 and Panjiangsaurus epicharis Chen and Cheng, 2003 might be junior synonyms of Guizhouichthyosaurus tangae Cao and Luo in Yin et al., 2000. It needs to re-describe the holotypes after a complete preparation for clarifying the taxonomic status of Typicusichthyosaurus tsaihuae Yu in Yin et al., 2000, Xinpusaurus bamaolinensis Cheng, 2003, Neosinosaurus hoangi (Zhou in Yin et al., 2000), Wayaosaurus geei Zhou in Yin et al., 2000, Wayaosaurus bellus Zhou in Yin et al., 2000 and Placochelys ? minutus Yin and Luo in Yin et al., 2000. | JIANG Dayong Ryosuke MOTAN LI Chun HAO Weicheng SUN Yuanlin SUN Zuoyu Lars SCHMITZ | 2005 | Acta Geologica Sinica(English Edition)2005，79，6： | 11 |

| 10 | Inhibition of bromophenols against PTP1B and anti-hyperglycemic effect of Rhodomela confervoides extract in diabetic rats显示文摘Protein tyrosine phosphatase 1B (PTP1B) plays an important role as a negative regulator in insulin signaling pathways. PTP1B is an effective target for the treatment of type 2 diabetes mellitus. Four bromophenol derivatives from red algae Rhodomela confervoides, 2,2′,3,3′-tetrabromo-4,4′,5,5′-tetra- hydroxydiphenyl methane (1), 3-bormo-4,5-bis(2,3-dibromo-4,5-dihydroxybenzyl) pyrocatechol (2), bis(2,3-dibromo-4,5-dihydroxybenzyl) ether (3) and 2,2′,3-tribromo-3′,4,4′,5-tetrahydroxy-6′-ethyloxy- methyldiphenylmethane (4) showed significant inhibitory activity against PTP1B (IC50 were 2.4, 1.7, 1.5 and 0.84 μmol/L, respectively) as potential therapeutical agents for the treatment of type 2 diabetes mellitus. The anti-hyperglycemic effects of the ethanol extracts from R. confervoides on streptozoto- cin-induced diabetes (STZ-diabetes) in male Wistar rats fed with high fat diet were investigated. The STZ-diabetic rats treated with medium-dose and high-dose alga extracts showed remarkable reductions in fasting blood glucose (FBG) as compared with the STZ-diabetic control. The results indicate that the in vivo anti-hyperglycemic activity of the R. confervoides extracts can be partially attributed to the in- hibitory actions against PTP1B of the bromophenol derivatives and that may be of clinical importance in improving the management of type 2 diabetes mellitus. | SHI DaYong XU Feng HE Juan LI Jing FAN Xiao HAN LiJun | 2008 | Chinese Science Bulletin2008，53，16： | 11 |
| 11 | Receiver function analysis for seismic structure of the crust and uppermost mantle in the Liupanshan area, China显示文摘A portable broadband seismic array was deployed from the northeast Tibetan Plateau to the southwest Ordos block, China. The seismic structure of the crust and uppermost mantle of the Liupanshan area is obtained using receiver function analysis of teleseismic body waves. The crustal thickness and Poisson's ratios are estimated by stacking the weighted amplitudes of receiver functions. Our results reveal complex seismic phases in the Liupanshan area, implying intense deformation at the boundary between the Tibetan Plateau and the Ordos block. The average crustal thickness is 51.5 km in the northeast Tibetan Plateau, 53.5 km in the Liupan Mountain and 50 km in the southwest Ordos block, resulting in a concave Moho beneath the Liupan Mountain. The Poisson's ratio of the Liupanshan area varies between 0.27-0.29, higher than the value of 0.25-0.26 to the east and west of the Liupan Mountain, suggesting partial melting in the lower crust. The variance in Poisson's ratio across the Liupan Mountain indicates notable changes in the crustal composition and mechanical properties, which may be formed by the northeastward flow of the Tibetan lower crust during the India-Eurasia collision. | TONG WeiWei WANG LiangShu MI Ning XU MingJie LI Hua YU DaYong LI Cheng LIU ShaoWen LIU Mian Eric SanDvol | 2007 | Science China Earth Sciences2007，50，z2： | 9 |
| 12 | Long Non-coding RNAs and Their Biological Roles in Plants显示文摘With the development of genomics and bioinformatics, especially the extensive applications of high-throughput sequencing technology, more transcriptional units with little or no protein-coding potential have been discovered. Such RNA molecules are called nonprotein-coding RNAs(npc RNAs or nc RNAs). Among them, long npc RNAs or nc RNAs(lnpc RNAs or lnc RNAs) represent diverse classes of transcripts longer than 200 nucleotides. In recent years, the lnc RNAs have been considered as important regulators in many essential biological processes. In plants, although a large number of lnc RNA transcripts have been predicted and identified in few species, our current knowledge of their biological functions is still limited.Here, we have summarized recent studies on their identification, characteristics, classification,bioinformatics, resources, and current exploration of their biological functions in plants. | Xue Liu Lili Hao Dayong Li Lihuang Zhu Songnian Hu | 2015 | Genomics, Proteomics & Bioinformatics2015，13，3： | 9 |
| 13 | Using the nematode Caenorhabditis elegans as a model animal for assessing the toxicity induced by microcystin-LR显示文摘Among more than 75 variants of microcystin(MC),microcystin-LR(MC-LR) is one of the most common toxins.In this study,the feasibility of using Caenorhabditis elegans to evaluate MC-LR toxicity was studied.C.elegans was treated with MC-LR at different concentrations ranging from 0.1 to 80 μg/L.The results showed that MC-LR could reduce lifespan,delay development,lengthen generation time,decrease brood size,suppress locomotion behavior,and decreases hsp-16-2-gfp expression.The endpoints of generation time,brood size,and percentage of the population expressing hsp-16-2-gfp were very sensitive to 1.0 μg/L of MC-LR,and would be more useful for the evaluation of MC-LR toxicity.Furthermore,the tissue-specific hsp-16-2-gfp expressions were investigated in MC-LR-exposed animals,and the nervous system and intestine were primarily affected by MC-LR.Therefore,the generation time,brood size,and hsp-16-2-gfp expression in C.elegans can be explored to serve as valuable endpoints for evaluating the potential toxicity from MC-LR exposure. | LI Yunhui WANG Yang YIN Lihong PU Yuepu WANG Dayong | 2009 | Journal of Environmental Sciences2009，21，3： | 9 |
| 14 | Coupling and propagating of mesoscale sea level variability between the western Pacific and the South China Sea显示文摘The coupling and propagating features of mesoscale sea level variability between the western Pacific (WP) and the South China Sea (SCS) were studied based on time series analyses of satellite altimeter measured, along-track sea surface height anomalies (SSHA) along 21°N and the slope of the northern SCS. The analyses show that mesoscale sea level fluctuations in the WP have rather limited coherent effects on the SCS, and no statistically significant propagation of mesoscale variability through the Luzon Strait was observed except in the 45-day band. Evidence suggests that the 45-day fluctuation is very much likely a character of the Kuroshio originating from its low-latitude beginning. It is also sug- gested that the westward propagating Rossby waves will deform when they encounter the dynamical barrier of the Kuroshio. The Kuroshio will then acts on the SCS in its own way. The SCS is a relatively isolated system in the sense of coupling and propagating of oceanic mesoscale waves. | LI Li JING ChunSheng ZHU DaYong | 2007 | Chinese Science Bulletin2007，52，12： | 8 |
| 15 | Experimental study on moving boundaries of fluid flow in porous media显示文摘Researches on the boundary shape of fluid flow in porous media play an important role in engineering practices, such as petroleum exploitation, nuclear waste disposal and groundwater contamination. In this paper, six types of artificial porous samples (emery jade) with different porosities are manufactured. With the background of slow flow in porous media, laboratory experiments are carried out by observing the movement of five types of fluids with different dynamic viscosities in various types of porous media. A digital video recorder is employed to record the complete process of the fluid flow in the porous media. Based on the digital photos of the moving boundaries of fluid flow in porous media, the average displacement and fractal dimension of the moving boundary are estimated for different combinations of porosity and dynamic viscosity. Moreover, the evolution behavior of the average velocity and fractal dimension of the moving boundary with time is known. The statistical relations of the average velocity, the fractal dimension of the moving boundary and the porosity of porous media and the dynamic vis- cosity of fluids are proposed in this paper. It is shown that the front shape of the moving boundary of fluid flow in porous media is an integrated result of the porosity of porous media and the dynamic viscosity of fluids. | ZHOU HongWei ZHANG YaHeng LI AiMin QIU DaYong | 2008 | Chinese Science Bulletin2008，53，16： | 8 |
| 16 | Simulation of spatially correlated earthquake ground motions for engineering purposes显示文摘A new model to simulate spatially correlated earthquake ground motions is developed. In the model, the main factors that characterize three distinct effects of spatial variability, namely, the incoherency effect, the wave-passage effect and the site-response effect, are taken into account, and corresponding terms/parameters are incorporated into the well known model of uniform ground motions. Some of these terms/parameters can be determined by the root operation, and others can be calculated directly. The proposed model is fi rst verif ied theoretically, and examples of ground motion simulations are provided as a further illustration. It is proven that the ensemble expected value and the ensemble auto-/cross-spectral density functions of the simulated ground motions are identical to the target spectral density functions. The proposed model can also be used to simulate other correlated stochastic processes, such as wave and wind loads. | Wu Yongxin Gao Yufeng Li Dayong | 2011 | Earthquake Engineering and Engineering Vibration2011，10，2： | 7 |
| 17 | Immunogenicity analysis following human immunodeficiency virus recombinant DNA and recombinant vaccinia virus Tian Tan prime-boost immunization显示文摘This study assessed and compared the immunogenicity of various immunization strategies in mice using combinations of recombinant DNA(pCCMp24) and recombinant attenuated vaccinia virus Tian Tan(rddVTT-CCMp24).Intramuscular immunization was performed on days 0(prime) and 21(boost).The immunogenicity of the vaccine schedules was determined by measuring human immunodeficiency virus(HIV)-specific binding antibody levels and cytokine(interleukin-2 and interleukin-4) concentrations in peripheral blood,analyzing lymphocyte proliferation capacity against HIV epitopes and CD4 + /CD8 + cell ratio,and monitoring interferon-gamma levels at different times post-immunization.The results showed that pCCMp24,rddVTT-CCMp24 and their prime-boost immunization induced humoral and cellular immune responses.The pCCMp24/rddVTT-CCMp24 immunization strategy increased CD8 + T cells and induced more IFN-γ-secreting cells compared with single-shot rDNA.The prime-boost immunization strategy also induced the generation of cellular immunological memory to HIV epitope peptides.These results demonstrated that prime-boost immunization with rDNA and rddVTT-CCMp24 had a tendency to induce greater cellular immune response than single-shot vaccinations,especially IFN-γ response,providing a basis for further studies. | LIU CunXia DU ShouWen LI Chang WANG YuHang WANG MaoPeng LI Yi YIN RongLan LI Xiao REN DaYong QIN YanQing REN JingQiang JIN NingYi | 2013 | Science China(Life Sciences)2013，56，6： | 7 |
| 18 | Seasonal variation of surface currents in the southwestern Taiwan Strait observed with HF radar显示文摘Long-term measurements from a pair of High-Frequency radar systems deployed near the coast of southern Fujian Province showed that surface currents in the southwestern Taiwan Strait were com-posed mainly of the monsoon-driven, seasonal fluctuation of longshore current and a persistent northeastward background flow with speeds around 10 cm/s. Measurements from bottom-moored ADCPs further indicated that below the surface Ekman layer longshore currents also directed to the north all year round. | ZHU DaYong LI Li LI Yan GUO XiaoGang | 2008 | Chinese Science Bulletin2008，53，15： | 7 |
| 19 | Antifatigue,Antioxidant and Immunoregulatory Effects of Peptides Hydrolyzed from Manchurian Walnut(Juglans mandshurica Maxim.) on Mice显示文摘The Manchurian walnut(Juglans mandshurica Maxim.) is rich in proteins, whereas this resource has not been used efficiently. The antifatigue, antioxidative and immunoregulatory effects of Manchurian walnut hydrolysate peptides(MWHPs)were evaluated in this study. MWHPs with a degree of hydrolysis of 32.23% were ultrafiltered and divided into three fractions,namely, high(> 10 k Da), medium(3–10 kDa), and low molecular weight(< 3 kDa), and then fed to mice continuously at doses of 200, 400 or 800 mg/(kg·d). The antifatigue, antioxidative, and immunoregulatory effects of the peptides were tested on the second and fourth weeks of MWHP administration. Results showed that low-molecular-weight MWHPs exerted significant antifatigue(prolonging swimming time, elevating liver glycogen contents, and reducing lactic acid contents), antioxidative(enhancing superoxide dismutase(SOD), GSH-Px, and catalase(CAT) activities and reducing malondialdehyde(MDA) content), and immunoregulatory(raising the immune-organ index and promoting T-lymphocyte proliferation and s Ig A secretion in the intestinal tract) effects. This research indicates that MWHPs have potential applications in health care and may be developed as a base for new functional foods. | FANG Li REN Dayong CUI Lingyu LIU Chunlei WANG Ji LIU Wei MIN Weihong LIU Jingsheng | 2018 | Grain & Oil Science and Technology2018，1，1： | 6 |
| 20 | Theoretical framework of dualistic nature–social water cycle显示文摘The global climate change and intensification of human activities in recent decades have made profound changes in hydrological cycle processes and water resources,and produced serious water problems and water crisis in many areas.The main reason is that the driving force of water cycle,the structure of water cycle,and the parameters of water cycle have dualistically evolved under the influence of human activities,and consequently resulted in reduction of runoff water resources,water pollution,and degradation of natural ecosystems.In order to realize of the safety aim of water supply,water environment,and ecosystem in area which is short of water resources,scientific regulation of water resources must take basin water cycle system as the unified base,and the first scientific basis is the awareness of the internal mechanism and law of water cycle evolution under highly intensive human activities.This article discussed four aspects of dualistic water cycle evolution,including its history in China,its theory,its characteristics in a typical basin,and its description of integral structure,along with the conceptive model system to quantify it.This article can be a reference to the basic cognition of water cycle evolution in a changing environment,and the study of water resources reduction reasons in the contemporary age. | Dayong Qin Chuiyu Lu Jiahong Liu Hao Wang Jianhua Wang Haihong Li Junyin Chu Genfa Chen | 2014 | Chinese Science Bulletin2014，59，8： | 5 |
