| 1 | Fractionation of Heavy Metals in Soils as Affected by Soil Types and Metal Load Quantity显示文摘Two series of soil subsamples, by spiking copper(Cu),lead(Pb),zinc(Zn)and cadmium(Cd)in an orthogonal design,were prepared using red soil and brown soil,respectively.The results indicated that heavy metal fractions in these soil subsamples depended not only on soil types,but also on metal loading quantity as well as on interactions among metals in soil.Lead and Cu in red soil appeared mostly in weakly specifically adsorbed(WSA),Fe and Mn oxides bound(OX),and residual(RES)fractions.Zine cxisted in all fractions except organic bound one,and Cd was major in water soluble plus exchangeable(SE)one.Different from the results of red soil,Pb and Cu was present in brown soil in all fractions except organic one,but over 75% of Zn and 90% of Cd existed only in SE fraction.Meanwhile,SE fraction for any metal in red soil was lower than that in brown soil and WSA and OX fractions were higher.It is in agreernent with low cation exchange capacity and large amounts of metal oxides included in red soil.Metal fractions in soil,especially for water soluble plus exchangeable one ,were obviously influenced by other coexisting metals.The SE fraction of heavy metals increased with increasing loading amounts of metals in red soil but not obviously in brown soil,which suggest that metal availability be easily affected by their total amounts spiked in red soil.In addition,more metals in red soil were extracted with 0.20 mol L^-1 NH4Cl(pH5.40)than that with 1.0 mol L^-1 Mg(NO3)2(pH7.0),but the reverse happened in brown soil,implicating significantly different mechanisms of metal desorption from red soil and brown soil. | ZHOU DONGMEI, CHEN HUAIMAN, HAO XIUZHEN and WANG YUJUNInstitute of Soil Science, the Chinese Academy of Sciences, Nanjing 210008 (China) | 2002 | Pedosphere2002，12，4： | 33 |
| 2 | Effect of temperature and moisture on soil organic carbon mineralization of predominantly permafrost peatland in the Great Hing'an Mountains,Northeastern China显示文摘Boreal peatlands represent a large global carbon pool.The relationships between carbon mineralization,soil temperature and moisture in the permafrost peatlands of the Great Hing'an Mountains,China,were examined.The CO2 emissions were measured during laboratory incubations of samples from four sites under different temperatures(5,10,15,and 20°C) and moisture contents(0%,30%,60%,100% water holding capacity(WHC) and completely water saturated).Total carbon mineralization ranged from 15.51 to 112.92 mg C under the treatments for all sites.Carbon mineralization rates decreased with soil depth,increased with temperature,and reached the highest at 60% WHC at the same temperature.The calculated temperature coefficient(Q10) values ranged from 1.84 to 2.51 with the soil depths and moisture.However,the values were not significantly affected by soil moisture and depth for all sites due to the different peat properties(P > 0.05).We found that the carbon mineralization could be successfully predicted as a two-compartment function with temperature and moisture(R2 > 0.96) and total carbon mineralization was significantly affected by temperature and moisture(P < 0.05).Thus,temperature and moisture would play important roles in carbon mineralization of permafrost peatlands in the Great Hing'an Mountains,indicating that the permafrost peatlands would be sensitive to the environment change,and the permafrost peatlands would be potentially mineralized under future climate change. | Xianwei Wang Xiuzhen Li Yuanman Hu Jiujun Lv Ju Sun Zongmei Li Zhifeng Wu | 2010 | Journal of Environmental Sciences2010，22，7： | 26 |
| 3 | Global blue carbon accumulation in tidal wetlands increases with climate change显示文摘Coastal tidal wetlands produce and accumulate significant amounts of organic carbon(C)that help to mitigate climate change.However,previous data limitations have prevented a robust evaluation of the global rates and mechanisms driving C accumulation.Here,we go beyond recent soil C stock estimates to reveal global tidal wetland C accumulation and predict changes under relative sea level rise,temperature and precipitation.We use data from literature study sites and our new observations spanning wide latitudinal gradients and 20 countries.Globally,tidal wetlands accumulate 53.65(95%CI:48.52-59.01)Tg C yr^(-1),which is~30%of the organic C buried on the ocean floor.Modeling based on current climatic drivers and under projected emissions scenarios revealed a net increase in the global C accumulation by2100.This rapid increase is driven by sea level rise in tidal marshes,and higher temperature and precipitation in mangroves.Countries with large areas of coastal wetlands,like Indonesia and Mexico,are more susceptible to tidal wetland C losses under climate change,while regions such as Australia,Brazil,the USA and China will experience a significant C accumulation increase under all projected scenarios. | Faming Wang Christian J.Sanders Isaac R.Santos Jianwu Tang Mark Schuerch Matthew L.Kirwan Robert E.Kopp Kai Zhu Xiuzhen Li Jiacan Yuan Wenzhi Liu Zhian Li | 2021 | National Science Review2021，8，9： | 22 |
| 4 | Effect of Reclamation Time and Land Use on Soil Properties in Changjiang River Estuary,China显示文摘The objective of this study is to analyze soil physical and chemical properties,soil comprehensive functions and impact factors after different years of reclamation.Based on the survey data taken from 216 soil sampling points in the Fengxian Reclamation Area of the Changjiang (Yangtze) River Estuary,China in April 2009 and remotely sensed TM data in 2006,while by virtue of multivariate analysis of variance (MANOVA),geo-statistical analysis (GA),prin-cipal component analysis (PCA) and canonical correspondence analysis (CCA),it was concluded that:1) With the in-crease in reclamation time,soil moisture,soil salinity,soil electric conductivity and soil particle size tended to decline,yet soil organic matter tended to increase.Soil available phosphorous tended to increase in the early reclamation period,yet it tended to decline after about 49 years of reclamation.Soil nitrate nitrogen,soil ammonia nitrogen and pH changed slightly in different reclamation years.Soil physical and chemical properties reached a steady state after about 30 years of reclamation.2) According to the results of PCA analysis,the weighted value (0.97 in total) that represents soil nutrient factors (soil nitrate nitrogen,soil organic matter,soil available phosphorous,soil ammonia nitrogen,pH and soil particle size) were higher than the weighted value (0.48 in total) of soil limiting factors (soil salinity,soil elec-tric conductivity and soil moisture).The higher the F value is,the better the soil quality is.3) Different land use types play different roles in the soil function maturity process,with farmlands providing the best contribution.4) Soil physi-cal and chemical properties in the reclamation area were mainly influenced by reclamation time,and then by land use types.The correlation (0.1905) of the composite index of soil function (F) with reclamation time was greater than that with land use types (-0.1161). | SUN Yongguang LI Xiuzhen ülo MANDER HE Yanlong JIA Yue MA Zhigang GUO Wenyong XIN Zaijun | 2011 | Chinese Geographical Science2011，21，4： | 17 |
| 5 | Rocky Desertification Risk Zone Delineation in Karst Plateau Area:A Case Study in Puding County,Guizhou Province显示文摘Karst rocky desertification is a geo-ecological problem in Southwest China.The rocky desertification risk zone delineation could be used as a guide for the regional and hierarchical rocky desertification management and prevention.We chose the middle and lower reaches of the Houzhai underground basin on the karst plateau in Puding County, Guizhou Province, China as the study area and selected land use type, elevation, slope, aspect, lithology and settlement buffer as the main driving factors of the rocky desertification.The potential risk of rocky desertification was quantified with the factor-weights union method and statistical analysis method.Five grades of rocky desertification risk were delineated based on Geographic Information System.The extremely low, low, moderate, high and extremely high rocky desertification risk zones accounted for 5.01%, 44.17%, 33.92%, 15.59% and 1.30%, respectively.As a whole, the rocky desertification risk level was moderate because the area of low and moderate rocky desertification risk zones occupied 78.09% of the study area.However, more than half of the area(about 50.81%) was predicted to have moderate rocky desertification risk and above, indicating that the study area was subject to rocky desertification.Rocky desertification risk was higher in the southeast and lower in the northwest of the study area.Distinct differences in the distribution of rocky desertification risk zones corresponding to different factors have been found. | ZHANG Panpan HU Yuanman XIAO Duning LI Xiuzhen YIN Jie HE Hong S | 2010 | Chinese Geographical Science2010，20，1： | 15 |

| 8 | Assessing the Ecological Quality of Nanjing during Its Urbanization Process by Using Satellite,Meteorological,and Socioeconomic Data显示文摘Assessing the ecological status of different districts within a city undergoing urbanization is challenging given their complex surface types and fast pace of development.In this study,we utilized satellite data obtained from Landsat5/TM(Thematic Mapper)and Landsat 8/OLI(Operational Land Imager)images in conjunction with meteorological and socioeconomic data to construct a remote sensing ecological index(RSEI)for monitoring the ecological quality of Nanjing,Jiangsu Province.A higher RSEI value corresponded to better ecological quality.Five ratings were associated with RSEI values of city districts:very poor,poor,average,good,and excellent.In Nanjing,the percentage of areas evidencing good RSEI ratings decreased from 55.9%in 2000 to 48.0%in 2018,whereas there was a slight increase in areas with very poor RSEI ratings during this period.Of the 11 city districts,16.8%,21.8%,and 61.4%respectively evidenced the increasing,decreasing,and stable ecological quality relative to their quality in 2000.Of the11 administrative districts in Nanjing,the main urban districts evidenced increased RSEI values in 2018 compared with those in 2000,with the improved areas exceeding the ones that had deteriorated in these districts.However,the ecological quality of new urban and ed because of the urban expansion,with areas that had deteriorated exceeding the improved ones.Of the three protected ecological zones,the quality of Zijin Mountain National Forest Park was considerably better than that of Laoshan and Jiangxinzhou.Overall,the urbanization rate and RSEI evidenced a high negative correlation coefficient value(-0.76).The urbanization process of Nanjing induced a declining trend for the ecological quality,indicating the need of strong protection measures for the maintenance or improvement of its ecological environment. | Xin HANG Yachun LI Xiaochun LUO Min XU Xiuzhen HAN | 2020 | Journal of Meteorological Research2020，34，2： | 10 |
| 9 | Numerical analysis of respiratory flow patterns within human upper airway显示文摘A computational fluid dynamics (CFD) approachis used to study the respiratory airflow dynamics within ahuman upper airway. The airway model which consists ofthe airway from nasal cavity, pharynx, larynx and tracheato triple bifurcation is built based on the CT images of ahealthy volunteer and the Weibel model. The flow characteristicsof the whole upper airway are quantitatively describedat any time level of respiratory cycle. Simulation results ofrespiratory flow show good agreement with the clinical measures,experimental and computational results in the literature.The air mainly passes through the floor of the nasalcavity in the common, middle and inferior nasal meatus. Thehigher airway resistance and wall shear stresses are distributedon the posterior nasal valve. Although the airways ofpharynx, larynx and bronchi experience low shear stresses,it is notable that relatively high shear stresses are distributedon the wall of epiglottis and bronchial bifurcations.Besides, two-dimensional fluid-structure interaction modelsof normal and abnormal airways are built to discuss theflow-induced deformation in various anatomy models. The result shows that the wall deformation in normal airway isrelatively small. | Ying Wang Yingxi Liu Xiuzhen Sun Shen Yu Fei Gao | 2009 | Acta Mechanica Sinica2009，25，6： | 9 |

| 12 | The Discovery of Natural Native Uranium and Its Significance显示文摘This study analyzed the composition and uranium valence of pitchblendes sampled from the hydrothermal Guidong and Zhuguang uranium deposits of the middle Nanling metallogenic belt, Southern China using X-ray photoelectron spectroscopy(XPS).A revolutionary discovery is that the uranium not only exists in the forms of tetravalent and hexavalent uranium oxides, but also occurs in the form of native uranium.This is the first discovery of the existence of native uranium in nature.It greatly helps to reveal the origin of hydrothermal mineralization of uranium, and also has great significance for studying the thermal energy, formation and evolution of the earth. | LI Ziying HUANG Zhizhang LI Xiuzhen GUO Jian FAN Chou | 2015 | Acta Geologica Sinica(English Edition)2015，89，5： | 8 |
| 13 | Self-organizing feature map neural network classification of the ASTER data based on wavelet fusion显示文摘Most methods for classification of remote sensing data are based on the statistical parameter evaluation with the assumption that the samples obey the normal distribution. How-ever, more accurate classification results can be obtained with the neural network method through getting knowledge from environments and adjusting the parameter (or weight) step by step by a specific measurement. This paper focuses on the double-layer structured Kohonen self-organizing feature map (SOFM), for which all neurons within the two layers are linked one another and those of the competition layers are linked as well along the sides. Therefore, the self-adapting learning ability is improved due to the effective competition and suppression in this method. The SOFM has become a hot topic in the research area of remote sensing data classi-fication. The Advanced Spaceborne Thermal Emission and Reflectance Radiometer (ASTER) is a new satellite-borne remote sensing instrument with three 15-m resolution bands and three 30-m resolution bands at the near infrared. The ASTER data of Dagang district, Tianjin Munici-pality is used as the test data in this study. At first, the wavelet fusion is carried out to make the spatial resolutions of the ASTER data identical; then, the SOFM method is applied to classifying the land cover types. The classification results are compared with those of the maximum likeli-hood method (MLH). As a consequence, the classification accuracy of SOFM increases about by 7% in general and, in particular, it is almost as twice as that of the MLH method in the town. | HASI Bagan MA Jianwen LI Qiqing HAN Xiuzhen LIU Zhili | 2004 | Science China Earth Sciences2004，47，7： | 7 |

| 16 | Histopathological Observation of Lymphocystis Disease and Lymphocystis Disease Virus (LCDV) Detection in Cultured Diseased Sebastes schlegeli显示文摘Lymphocystis nodules occurring in the cultured sting fish Sebastes schlegeli were observed under light and electron microscope. Lymphocystis disease virus (LCDV) in the tissues of diseased fish was detected with indirect immunofluorescence test (IFAT). Results showed that lymphocystis cells had overly irregular nuclei, basophilic intracytoplasmic inclusion bodies with virions budding from the surface, and hyaline capsules outside the cell membrane. Numerous virus particles about 200 nm in diameter scat- tered in the cytoplasm, electron-dense particles 70-80 nm in diameter filled in perinuclear cisterna, and membrane-enveloped parti- cles with electron-dense core of 70-80 nm appeared around cellular nucleus. IFAT using monoclonal antibody against LCDV from Paralichthys olivaceus revealed that specific green fluorescence was present in the cytoplasm of lymphocystis cells, epithelium of stomach, gill lamellae, and muscular fibers under epidermis of S. schlegeli, just as that in the cytoplasm of lymphocystis cells of P. olivaceus, suggesting the presence of LCDV in these tissues. | SHENG Xiuzhen ZHAN Wenbin XU Songjuan CHENG Shunfeng | 2007 | Journal of Ocean University of China2007，6，4： | 6 |
| 17 | Insulin requirement profiles and related factors of insulin pump therapy in patients with type 2 diabetes显示文摘Continuous subcutaneous insulin infusion(CSII)is an effective therapy to control hyperglycemia in both patients with type 1 diabetes and type 2 diabetes.However,there is little data investigating the insulin dose setting during CSII therapy in type 2 diabetes to achieve optimal glycemic control and avoid the risk of hypoglycemia.Thus,this study is aimed to assess the dose characteristics of insulin requirement and explore the related clinical factors in patients with type 2 diabetes who were treated with CSII.A total of 327 patients(195 males)aged 52.9±12.5 years old were included in this study.Patients were treated with CSII to achieve the target fasting capillary blood glucose(4.4-7.0 mmol L^(-1))and 2-h postprandial capillary blood glucose(4.4-10.0 mmol L^(-1))by adjusting insulin infusion according to the seven-point capillary blood glucose profiles.Total daily insulin dose(TDD),total daily insulin dose per kilogram(TDD kg-1)and the ratio of total basal insulin dose(TBD)to TDD(%TBa)were calculated after patients achieved the glucose targets for at least 3 days via 1-2 weeks of CSII treatment.And insulin dose,insulin dosing patterns and the relevant clinical factors were analyzed.The mean ratio of basal/bolus insulin distribution of all patients was 40%:60%.Patients with central obesity needed more TDD(51.3±17.1 U versus 43.5±14.0 U,P<0.05)and TDD kg^(-1)(0.8±0.3 U kg^(-1)versus 0.7±0.2 U kg^(-1),P<0.05)than those without central obesity.Pearson's correlation analysis demonstrated that TDD was positively correlated with body mass index(BMI),waist circumference(WC),baseline fasting plasma glucose(FPG),fasting C-peptide level,2 h-postprandial C-peptide level and time to achieve glycemic target(all P<0.05);TDD kg^(-1)was positively correlated with waist-to-hip ratio(WHR),baseline FPG,glycosylated hemoglobin Ale(HbAlc),fasting C-peptide level and time to achieve glycemic target,and negatively correlated with BMI(all P<0.05).Multiple linear regression analyses revealed that BMI(β=1.796,P<0.01),WC(β=0.109,P<0.01),baseline FPG(β=1.459,P<0.01)and HbAlc(β=0.930,P=0.021)were independently related to TDD.Gender(β=-0.107,P=0.003),WC(β=0.005,P=0.029),baseline FPG(β=0.025,P<0.01)and HbAlc(β=0.016,β=0.007)were independently associated with TDD kg^(-1).Gender(β=-0.015,P=0.048)and disease duration(β=0.134,P=0.029)were independently associated with%TBa.%TBa is around 40%in Chinese patients with type 2 diabetes treated with CSII when glycemic control is achieved.In addition to body weight or BMI,WC and glucose levels before CSII should be considered to set TDD.Patients with central obesity or poor glycemic control might need more TDD.Higher%TBa should be considered in female patients or patients with longer disease duration. | Xubin Yang Hongrong Deng Xiuzhen Zhang Daizhi Yang Jinhua Yan Bin Yao Jianping Weng Wen Xu | 2019 | Science China(Life Sciences)2019，62，11： | 6 |
| 18 | Empirical-Statistical Models Based on Remote Sensing for Estimating the Volume of Landslides Induced by the Wenchuan Earthquake显示文摘The Wenchuan Ms 8.0 earthquake on May 12, 2008 induced a huge number of landslides. The distribution and volume of the landslides are very important for assessing risks and understanding the landslide - debris flow - barrier lake - bursts flood disaster chain. The number and the area of landslides in a wide region can be easily obtained by remote sensing technique, while the volume is relatively difficult to obtain because it requires some detailed geometric information of slope failure surface and sub-surface. Different empirical models for estimating landslide volume were discussed based on the data of 107 landslides in the earthquake-stricken area. The volume data of these landslides were collected by field survey. Their areas were obtained by interpreting remote sensing images while their apparent friction coefficients and height were extracted from the images unifying DEM (digital elevation model). By analyzing the relationships between the volume and the area, apparent friction coefficients, and the height, two models were established, one for the adaptation of a magnitude scale landslide events in a wide range of region, another for the adaptation in a small scope. The correlation coefficients (R2) are 0.7977 and 0.8913, respectively. The results estimated by the two models agree well with the measurement data. | FAN Jianrong LI Xiuzhen GUO Fenfen GUO Xiang | 2011 | Journal of Mountain Science2011，8，5： | 6 |
| 19 | Facile one-step synthesis of functionalized biochar from sustainable prolifera-green-tide source for enhanced adsorption of copper ions显示文摘The use of biochars formed by hydrothermal carbonization for the treatment of contaminated water has been greatly limited,due to their poorly developed porosity and low content of surface functional groups.Also,the most common modification routes inevitably require post-treatment processes,which are time-consuming and energy-wasting.Hence,the objective of this research was to produce a cost-effective biochar with improved performance for the treatment of heavy metal pollution through a facile one-step hydrothermal carbonization process coupled with ammonium phosphate,thiocarbamide,ammonium chloride or urea,without any posttreatment.The effects of various operational parameters,including type of modification reagent,time and temperature of hydrothermal treatment,and ratio of modification reagent to precursor during impregnation,on the copper ion adsorption were examined.The adsorption data fit the Langmuir adsorption isotherm model quite well.The maximum adsorption capacities(mg/g) of the biochars towards copper ions followed the order of 40-8 h-1.0-APBC(95.24) > 140-8 h-0-BC(12.52) > 140-8 h-1.0-TUBC(12.08) > 140-8 h-1.0-ACBC(7.440) > 140-8 h-1.0-URBC(5.277).The results indicated that biochars modified with ammonium phosphate displayed excellent adsorption performance toward copper ions,which was 7.6-fold higher than that of the pristine biochar.EDX and FT-IR analyses before and after adsorption demonstrated that the main removal mechanism involved complexation between the phosphate groups on the surface of the modified biochars and copper ions. | Yuan Gao Xiuzhen Zhu Qinyan Yue Baoyu Gao | 2018 | Journal of Environmental Sciences2018，30，11： | 4 |
| 20 | Evaluation of the Biodiversity Conservation Function in Liaohe Delta Wetland,Northeastern China显示文摘The scientific evaluation of the wetland biodiversity conservation function is the basis of balanced wetland protection and development. Our research sought to provide references for the protection of wetland ecological environments as well as the related planning and management policies. The study established a fitting model for evaluating the biodiversity conservation function in the Liaohe Delta, northeastern China. The new model, the Wetland Biodiversity Conservation Indicator(WBCI), was with four input factors, including the vegetation coverage(VC), habitat suitability index(HI), land use and land cover(LULC) index(LI), and threat factor index(TI) of the LULC type. The values assigned to HI and TI were based on Integrated Valuation of Ecosystem Services and Tradeoffs(In VEST)habitat quality models. The weights of all the factors in WBCI were valued with the Principal Component Analysis(PCA). We evaluated the wetland biodiversity conservation function of Panjin, Liaohe Delta, China, by using the WBCI model based on Gaofen-1(GF-1) satellite data in 2018, and the result was verified with In VEST and other models. It showed that the output map was similar to that of In VEST, with the higher-quality habitat including the wetland, tidal flat, water body, and forest, as well as the lower-quality land use types including the paddy field, crop field, construction land, and land used by traffic. The wetland biodiversity conservation function was better in areas less affected by human disturbance, with very abundant species and good-quality habitat. It was poor in areas impacted by more frequent human activities such as the land cultivation, housing, and traffic, which led to the landscape fragmentation. The WBCI model provided a more accurate reflection of the bird distribution than the In VEST model. The WBCI model was able to reflect the difference in quality of each habitat grade, in contrast to the net primary productivity(NPP) method and species distribution models(SDMs). The new model was, therefore, simpler and suitable in reflecting the quality of wetland biodiversity function in the Liaohe Delta. | Wenying YU Ruipeng JI Xiuzhen HAN Long CHEN Rui FENG Jinwen WU Yushu ZHANG | 2020 | Journal of Meteorological Research2020，34，4： | 4 |
