| 1 | Heavy metal accumulation by panicled goldenrain tree(Koelreuteria paniculata) and common elaeocarpus(Elaeocarpus decipens) in abandoned mine soils in southern China显示文摘Phytoremediation can be used as a sustainable technology for mine spoil remediation to remove heavy metals.This study investigated the concentration of 7 heavy metal contamination in soil and plant samples at an abandoned mine site.We found that,after vegetation remediation at the abandoned mine site,the reduction rates for 7 heavy metals were in the range of 4.2%-86%,where reduction rates over 50% were achieved for four heavy metals(Zn,Mn,Cd,Ni).Transfer coeffcients of the panicled goldenrain tree(Koelreuteria paniculata Laxm) and the common elaeocarpus(Elaeocarpus decipens) for Zn,Mn,Ni,and Co were more than 1.Enrichment coeffcients of both trees for Mn were higher than 1.Our results suggest that the panicled goldenrain tree and the common elaeocarpus tree may act as accumulators in remediation.Moreover,the woody vegetation remediation in abandoned mining areas play an important role in improving scenery besides removing heavy metal from contaminated soil. | TIAN Dalun ZHU Fan YAN Wende Fang Xi XIANG Wenhua DENG Xiangwen WANG Guangjun PENG Changhui | 2009 | Journal of Environmental Sciences2009,21,3: | 11 |
| 2 | First light of the 1.8-m solar telescope–CLST显示文摘Large-aperture solar telescopes play an important role in solar observations and research,and require high temporal and spatial resolution[1].To solve some fundamental problems such as the solar dynamo,coronal heating,and the triggering of major solar eruptions,the spatial resolution for solar-atmosphere observation should reach at least 0.1 arcsec[2]. | ChangHui Rao NaiTing Gu XueJun Rao Cheng Li LanQiang Zhang JinLong Huang Lin Kong Ming Zhang YunTao Cheng Yi Pu Hua Bao YouMing Guo YangYi Liu JinSheng Yang LiBo Zhong ChangJun Wang Kai Fang XiaoJun Zhang DongHong Chen Cheng Wang XinLong Fan ZhiWu Yan KeLe Chen XiYa Wei Lei Zhu Hong Liu YongJian Wan Hao Xian WenLi Ma | 2020 | Science China(Physics,Mechanics & Astronomy)2020,63,10: | 6 |
| 3 | Selective hydrogenolysis of 5-hydroxymethylfurfural to 2,5-dimethylfuran over Co_3O_4 catalyst by controlled reduction显示文摘2,5-dimethyfuran(DMF), which is produced from 5-hydroxymethyfurfural(HMF) by hydrodeoxygenation(HDO), is a high quality fuel due to the high heating value, the high octane number and the suitable boiling point. Selective hydrogenation of HMF into liquid fuel DMF has been widely researched. In this paper, Co_3O_4 catalyst was prepared by co-precipitation and was reduced at different temperatures to form Co–CoO_x catalysts. The characterization of catalysts was tested by XRD, TEM, XPS, TPR, BET and NH3-TPD.Co–CoO_x possessed a high amount of Co metal and CoO_x acidic sites, wherein Co worked as the active hydrogenation sites and CoO_x acted as the acid promoter to facilitate the selective HDO of HMF to DMF.The synergistic effect of Co–CoO_x is the key for HDO of HMF, obtaining 83.3% of DMF yield at 170 °C, 12 h and the reduction temperature of 400 °C. This method not only saves the catalyst cost, but also promotes the utilization of biomass energy. | Dan Li Qiying Liu Changhui Zhu Haiyong Wang Chunhua Cui Chenguang Wang Longlong Ma | 2019 | Journal of Energy Chemistry2019,28,3: | 4 |
| 4 | Towards a paradigm for open and free sharing of scientific data on global change science in China显示文摘Despite great progress in data sharing that has been made in China in recent decades,cultural,policy,and technological challenges have prevented Chinese researchers from maximizing the availability of their data to the global change science community.To achieve full and open exchange and sharing of scientific data,Chinese research funding agencies need to recognize that preserva-tion of,and access to,digital data are central to their mission,and must support these tasks accord-ingly.The Chinese government also needs to develop better mechanisms,incentives,and rewards,while scientists need to change their behavior and culture to recognize the need to maximize the usefulness of their data to society as well as to other researchers.The Chinese research communi-ty and individual researchers should think globally and act personally to promote a paradigm of open,free,and timely data sharing,and to increase the effectiveness of knowledge development. | Changhui Peng Xinzhang Song Hong Jiang Qiuan Zhu Huai Chen Jing MChen Peng Gong Chang Jie Wenhua Xiang Guirui Yu Xiaolu Zhou | 2016 | Ecosystem Health and Sustainability2016,2,5: | 4 |
| 5 | Molecular analysis of rice plants harboring a multi-functional T-DNA tagging system显示文摘About 25,000 rice T-DNA insertional mutant lines were generated using the vector pCAS04 which has both promoter-trapping and activation-tagging function. Southern blot analysis revealed that about 40% of these mutants were single copy integration and the average T-DNA insertion number was 2.28. By extensive phenotyping in the field, quite a number of agronomically important mutants were obtained. Histochemical GUS assay with 4,310 primary mutants revealed that the GUS-staining frequency was higher than that of the previous reports in various tissues and especially high in flowers. The T-DNA flanking sequences of some mutants were isolated and the T-DNA insertion sites were mapped to the rice genome. The flanking sequence analysis demonstrated the different integration pattern of the right border and left border into rice genome. Compared with Arabidopsis and poplar, it is much varied in the T-DNA border junctions in rice. | Yimian Ma Luo Liu Chengguang Zhu Changhui Sun Bo Xu Jun Fang Jiuyou Tang Anding Luo Shouyun Cao Gupo Li Qian Qian Yongbiao Xue Chengcai Chu | 2009 | Journal of Genetics and Genomics2009,36,5: | 3 |
| 6 | Integrating a model with remote sensing observations by a data assimilation approach to improve the model simulation accuracy of carbon flux and evapotranspiration at two flux sites显示文摘Model simulation and in situ observations are often used to research water and carbon cycles in terrestrial ecosystems, but each of these methods has its own advantages and limitations. Combining these two methods could improve the accuracy of quantifying the dynamics of the water and carbon fluxes of an ecosystem. Data assimilation is an effective means of integrating modeling with in situ observation. In this study, the ensemble Kalman filter(En KF) and the unscented Kalman filter(UKF) algorithms were used to assimilate remotely sensed leaf area index(LAI) data with the Biome-BGC model to simulate water and carbon fluxes at the Harvard Forest Environmental Monitoring Site(EMS) and the Dinghushan site. After MODIS LAI data from 2000–2004 were assimilated into the improved Biome-BGC model using the En KF algorithm at the Harvard Forest site, the R2 between the simulated and observed results for NEE and evapotranspiration increased by 7.8% and 4.7%, respectively. In addition, the sum of the absolute error(SAE) and the root mean square error(RMSE) of NEE decreased by an average of 21.9% and 26.3%, and the SAE and RMSE of evapotranspiration decreased by 24.5% and 25.5%, respectively. MODIS LAI data of 2003 were assimilated into the Biome-BGC model for the Dinghushan site, and the R2 values between the simulated and observed results for NEE and evapotranspiration were increased by 6.7% and 17.3%, respectively. In addition, the SAE values of NEE and ET were decreased by 11.3% and 30.7%, respectively, and the RMSE values of NEE and ET decreased by 10.1% and 30.9%, respectively. These results demonstrate that the accuracy of carbon and water flux simulations can be effectively improved when remotely sensed LAI data are properly integrated with ecosystem models through a data assimilation approach. | ZHANG TingLong SUN Rui PENG ChangHui ZHOU GuoYi WANG ChunLing ZHU QiuAn YANG YanZheng | 2016 | Science China Earth Sciences2016,59,2: | 3 |
| 7 | First light of solar multi-conjugate adaptive optics at the 1-m new vacuum solar telescope显示文摘Observations play a leading role in any branches of astronomy,including solar physics.In order to solve fundamental problems,such as solar dynamo[1],coronal heating[2]and the triggering of major solar eruptions[3],solar observations with spatial resolution better than 0.1 arcsec are required.Such a goal cannot be achieved without the help of adaptive optics(AO),which eliminates the wavefront distortion caused by atmosphere turbulence[4,5].However,solar observations are performed over an extended field of | ChangHui Rao LanQiang Zhang Lin Kong YouMing Guo XueJun Rao Hua Bao Lei Zhu LiBo Zhong | 2018 | Science China(Physics,Mechanics & Astronomy)2018,61,8: | 2 |
| 8 | DEAP1 encodes a fasciclin-like arabinogalactan protein required for male fertility in rice显示文摘Arabinogalactan proteins(AGPs)are widely distributed in plant cells.Fasciclin-like AGPs(FLAs)belong to a subclass of AGPs that play important roles in plant growth and development.However,little is known about the biological functions of rice FLA.Herein,we report the identification of a male-sterile mutant of DEFECTIVE EXINE AND APERTURE PATTERNING1(DEAP1)in rice.The deap1 mutant anthers produced aberrant pollen grains with defective exine formation and a flattened aperture annulus and exhibited slightly delayed tapetum degradation.DEAP1 encodes a plasma membrane-associated member of groupⅢplant FLAs and is specifically and temporally expressed in reproductive cells and the tapetum layer during male development.Gene expression studies revealed reduced transcript accumulation of genes related to exine formation,aperture patterning,and tapetum development in deap1 mutants.Moreover,DEAP1 may interact with two rice D6 PROTEIN KINASE-LIKE3 s(OsD6PKL3s),homologs of a known Arabidopsis aperture protein,to affect rice pollen aperture development.Our findings suggested that DEAP1 is involved in male reproductive development and may affect exine formation and aperture patterning,thereby providing new insights into the molecular functions of plant FLAs in male fertility. | Dan Zhou Ting Zou Kaixuan Zhang Pingping Xiong Fuxing Zhou Hao Chen Gongwen Li Kaiyou Zheng Yuhao Han Kun Peng Xu Zhang Shangyu Yang Qiming Deng Shiquan Wang Jun Zhu Yueyang Liang Changhui Sun Xiumei Yu Huainian Liu Lingxia Wang Ping Li Shuangcheng Li | 2022 | Journal of Integrative Plant Biology2022,64,7: | 2 |

| 12 | Qinghai-tibetan plateau peatland sustainable utilization under anthropogenic disturbances and climate change显示文摘Often referred to as the“Third Pole,”China’s Qinghai-Tibetan Plateau developed large amounts of peatland owing to its unique alpine environment.As a renewable resource,peat helps to regulate the climate as well as performing other important functions.However,in recent years,intensifying climate change and anthropogenic disturbances have resulted in peatland degradation and consequently made sustainable development of peatland more difficult.This review summarizes peatland ecological and economic functions,including carbon sequestration,biodiversity conservation,energy supplies,and ecotourism.It identifies climate change and anthropogenic disturbances as the two key factors attributing to peatland degradation and ecosystem carbon loss.Current problems in environmental degradation and future challenges in peatland management under the effects of global warming are also discussed and highlighted. | Gang Yang Changhui Peng Huai Chen Faqin Dong Ning Wu Yanzheng Yang Yao Zhang Dan Zhu Yixin He Shengwei Shi Xiaoyang Zeng Tingting Xi Qingxiang Meng Qiuan Zhu | 2017 | Ecosystem Health and Sustainability2017,3,3: | 1 |

| 14 | Exposures to temperature beyond threshold disproportionately reduce vegetation growth in the northern hemisphere显示文摘In recent decades,terrestrial vegetation in the northern hemisphere(NH)has been exposed to warming and more extremely high temperatures.However,the consequences of these changes for terrestrial vegetation growth remain poorly quantifed and understood.By examining a satellite-based vegetation index,tree-ring measurements and land-surface model simulations,we discovered a consistent convex patern in the responses of vegetation growth to temperature exposure(TE)for forest,shrub and grass in both the temperate(30°-50°N)and boreal(50°-70°N)NH during the period of 1982-2012.Te response of vegetation growth to TE for the three vegetation types in both the temperate and boreal NH increased convergently with increasing temperature,until vegetation type-dependent temperature thresholds were reached.A TE beyond these temperature thresholds resulted in disproportionately weak positive or even strong negative responses.Vegetation growth in the boreal NH was more vulnerable to extremely high-temperature events than vegetation growth in the temporal NH.Te non-linear responses discovered here provide new insights into the dynamics of northern terrestrial ecosystems in a warmer world. | Xiuchen Wu Weichao Guo Hongyan Liu Xiaoyan Li Changhui Peng Craig D.Allen Cicheng Zhang Pei Wang Tingting Pei Yujun Ma Yuhong Tian Zhaoliang Song Wenquan Zhu Yang Wang Zongshan Li Deliang Chen | 2019 | National Science Review2019,6,4: | 0 |
| 15 | Nitrous oxide emissions from three temperate forest types in the Qinling Mountains,China显示文摘To understand soil N2O fluxes from temperate forests in a climate-sensitive transitional zone,N2O emissions from three temperate forest types(Pinus tabulaeformis,PTT;Pinus armandii,PAT;and Quercus aliena var.acuteserrata,QAT)were monitored using the static closed-chamber method from June 2013 to May 2015 in the Huoditang Forest region of the Qinling Mountains,China.The results showed that these three forest types acted as N2O sources,releasing a mean combined level of 1.35±0.56 kg N2O ha^-1 a^-1,ranging from0.98±0.37 kg N2O ha^-1 a^-1 in PAT to 1.67±0.41 kg N2O ha^-1 a^-1 in QAT.N2O emission fluctuated seasonally,with highest levels during the summer for all three forest types.N2O flux had a significantly positive correlation with soil temperature at a depth of 5 cm or in the water-filled pore space,where the correlation was stronger for temperature than for the water-filled pore space.N2O flux was positively correlated with available soil nitrogen in QAT and PAT.Our results indicate that N2O flux is mainly controlled by soil temperature in the temperate forest in the Qinling Mountains. | Wei Xue Changhui Peng Huai Chen Hui Wang Qiuan Zhu Yanzheng Yang Junjun Zhang Wanqin Yang | 2019 | Journal of Forestry Research2019,30,4: | 0 |
| 16 | Spatiotemporal analysis of the impact of urban landscape forms on PM_(2.5) in China from 2001 to 2020显示文摘Urban landscape forms can be effective in reducing increasing PM_(2.5) concentrations due to urbanization in China,making it crucially important to accurately quantify the spatiotemporal impact of urban landscape forms on PM_(2.5) variations.Three landscape indices and six control variables were selected to assess these impacts in 362 Chinese cities during different time scales from 2001 to 2020,using a spatiotemporal geographically weighted regression model,random forest models and partial dependence plots.The results show that there are spatiotemporal differences in the impacts of landscape indices on PM_(2.5).the proportion of urban green infrastructure(PLAND-UGI)and the fractal dimension of urban green infrastructure(FRACT-UGI)exacerbate PM_(2.5) concentrations in the northwest,the proportion of impervious surfaces(PLAND-Impervious)mitigates air pollution in northwest and southwest China,and shannon’s diversity index(SHDI)has seasonal differences in the northwest.PLAND-UGI is the landscape index with the largest contribution(30%)and interpretable range.The relationship between FRACT and PM_(2.5) was more complex than for other landscape indices.The results of this study contribute to a deeper understanding of the spatial and temporal differences in the impact of urban landscape patterns on PM_(2.5),contributing to clean urban development and sustainable development. | Shoutao Zhu Jiayi Tang Xiaolu Zhou Peng Li Zelin Liu Cicheng Zhang Ziying Zou Tong Li Changhui Peng | 2023 | International Journal of Digital Earth2023,16,1: | 0 |
