| 1 | Construction of habitat suitability models(HSMs) for benthic macroinvertebrate and their applications to instream environmental flows:A case study in Xiangxi River of Three Gorges Reservior region,China显示文摘Based on a long-term ecological monitoring, the present study chose the most dominant benthic macroinvertebrate (Baetis spp.) as tar- get organisms in Xiangxi River, built the habitat suitability models (HSMs) for water depth, current velocity and substrate, respectively, which is the first aquatic organisms model for habitat suitability in the Chinese Mainland with a long-term consecutive in situ measurement. In order to protect the biointegrity and function of the river ecosystem, the theory system of instream environmental flow should be cat- egorized into three hierarchies, namely minimum required instream flow (hydrological level), minimum instream environmental flow (bio- species level), and optimum instream environmental flow (ecosystem level). These three hierarchies of instream environmental flow models were then constructed with the hydrological and weighted usable area (WUA) method. The results show that the minimum required instream flow of Xiangxi River calculated by the Tennant method (10% of the mean annual flow) was 0.615 m3 s 1; the minimum instream environmental flow accounted for 19.22% of the mean annual flow (namely 1.182 m3 s 1), which was the damaged river channel flow in the dry season; and 42.91% of the mean annual flow (namely 2.639 m3 s 1) should be viewed as the optimum instream environmental flow in order to protect the health of the river ecosystem, maintain the instream biodiversity, and reduce the impact of small hydropower stations nearby the Xiangxi River. We recommend that the hydrological and biological methods can help establish better instream environmental flow models and design best management practices for use in the small hydropower station project. | Fengqing Li Qinghua Cai Xiaocheng Fu Jiankang Liu | 2009 | Progress in Natural Science:Materials International2009，19，3： | 18 |
| 2 | Structure Styles of Mesozoic-Cenozoic U-bearing Rock Series in Northern China显示文摘In Northern China,sandstone-type uranium(U) deposits are mostly developed in MesozoicCenozoic basins. These U deposits are usually hosted in unvarying horizons within the basins and exhibit typical U-forming sedimentary associations,which is referred to as U-bearing rock series. This study describes the structural features of U-bearing rock series within the main Mesozoic-Cenozoic Uproducing continental basins in Kazakhstan,Uzbekistan,and Russia in the western segment of the Central Asian Metallogenic Belt(CAMB),and Northern China in the eastern segment of the CAMB. We analyze the basic structural conditions and sedimentary environments of U-bearing rock series in Northern China and classify their structural styles in typical basins into river valley,basin margin,and intrabasin uplift margin types. The intrabasin uplift margin structural style proposed in this study can be used to indicate directions for the exploration of sandstone-type U deposits hosted in the center of a basin. At the same time,the study of structural style provides a new idea for exploring sandstone-type U deposits in Mesozoic-Cenozoic basins and it is of great significance to prospecting of sandstone-type uranium deposits. | JIN Ruoshi MIAO Peisen SIMA Xianzhang LI Jianguo ZHAO Hualei ZHAO Fengqing FEN Xiaoxi CHEN Yin CHEN Lulu ZHAO Lijun ZHU Qiang | 2016 | Acta Geologica Sinica(English Edition)2016，90，6： | 12 |
| 3 | Precambrian Geochronology, Chronotectonic Framework and Model of Chronocrustal Structure of the Zhongtiao Mountains显示文摘The Zhongtiao Mountains, a typical exposure area of Precambrian rocks, are a concentration area of vari-ous types of copper deposit. The rocks were dated using several dating methods. Based on the age data ob-tained by means of three methods, several aspects are dealt with: (1) the dating results obtained by differentmethods and their geological implications have been compared; (2) a chronotectonic framework has been con-structed by means of these reliable ages, which indicates that the ages of the rocks of the Proterozoic mobilebelt fall in a time span of 2400 to 2000 Ma during which global magmatic records are lacking and reflects theages of important events in the mobile belt; (3) according to the ages of inherited zircons, neodymium modelage of the depleted mantle sources (TDM) and geochemical and geological data, a model of Precambrianchronocrustal structure has been constructed, representing a typical for the North China craton. | Sun Dazhong Li Huimin Lin Yuanxian Zhou Huifang Zhao Fengqing Tang Min Tianjin Institute of Geology and Mineral Resources, Chinese Academy of Geological Sciences, Tianjin Fei Zhenbi | 1992 | Acta Geologica Sinica(English Edition)1992，66，1： | 10 |
| 4 | Variations and trends of the freezing and thaw- ing index along the Qinghai-Xizang Railway for 1966-2004显示文摘Annual freezing and thawing index of 7 meteorological stations along the Qing- hai-Xizang Railway were calculated based on daily maximum and minimum temperature records for 1966-2004. Trends of annual freezing and thawing index were analyzed using the Mann-Kendall test and a simple linear regression method. The results show that: 1) The mean annual freezing indices range from 95 to 2300℃·d and the mean annual thawing indi- ces range from 630 to 3250℃·d. The mean annual freezing index of the 7 stations exhibited decreasing trends with decreasing rate of -16.6– -59.1℃·d /10a. The mean annual thawing index of these 7 stations showed increasing trends with the related decreasing rate is 19.83–45.6℃·d /10a. 2) The MK trend test indicated the significant decreasing trends (significant at < 0.05 significant level) in the annual freezing index for most stations except for Golmud. The significant increasing trends can be observed in the annual thawing index for 4 stations except Golmud and Tuotuohe. Golmud was the only station with no trends in both annual freezing and annual thawing index. | JIANG Fengqing HU Ruji LI Zhen | 2008 | Journal of Geographical Sciences2008，18，1： | 7 |
| 5 | Utilization of Ogura CMS germplasm with the clubroot resistance gene by fertility restoration and cytoplasm replacement in Brassica oleracea L显示文摘Clubroot disease,a major plant root disease caused by Plasmodiophora brassicae,has become one of the most destructive diseases among cultivated cruciferous vegetables.However,clubroot-resistant Brassica oleracea materials are rare.A few clubroot-resistant cabbage varieties are available on the market,but all are Ogura cytoplasmic male sterile(CMS)types.Therefore,in this study,to reutilize the clubroot-resistant Ogura CMS germplasm of cabbage,a new fertility-restored Ogura CMS material,16Q2-11,was used as a bridge to transfer the clubroot resistance(CR)gene from the Ogura CMS cytoplasm to the normal cytoplasm by a two-step method(a fertility restoration and cytoplasm replacement method).In the first cross for fertility restoration of Ogura CMS clubroot-resistant cabbage(FRCRC),16Q2-11 was used as a restorer to cross with Ogura CMS materials containing the CR gene CRb2.Eleven Rfo-positive progenies were generated,of which four contained CRb2:F8-514,F8-620,F8-732 and F8-839.After inoculation with race 4 of P.brassicae,these four CRb2-positive individuals showed resistance.Furthermore,F8-514 and F8-839 were then used as male parents in the second cross of FRCRC to cross with cabbage inbred lines,resulting in the successful introgression of the CRb2 gene into the inbred lines.All offspring produced from this step of cross,which had a normal cytoplasm,showed a high resistance to race 4 of P.brassicae and could be utilized for the breeding of clubrootresistant cabbage varieties in the future.This is the first time that the Ogura CMS restorer has been used to restore the fertility of Ogura CMS clubroot-resistant cabbages,which could improve germplasm diversity in cabbage and provide a reference method for using CMS germplasm in Brassica crops. | Wenjing Ren Zhiyuan Li Fengqing Han Bin Zhang Xing Li Zhiyuan Fang Limei Yang Mu Zhuang Honghao Lv Yumei Liu Yong Wang Hailong Yu Yangyong Zhang | 2020 | Horticulture Research2020，7，1： | 7 |

| 8 | Spatial and temporal temperature variations in Xinjiang,China during 1961-2008显示文摘This study examines spatial and temporal changes in 16 extreme temperature indices at 37 weather stations in Xinjiang and their associations with changes in climate means during 1961-2008.Linear regression analyses reveal that significant increasing trends in temperature were observed over Xinjiang,with the rate of 0.13 °C/decade,0.24 °C/decade,and 0.52 °C/decade for annual mean temperature,annual maximum,and minimum temperature,respectively.Annual frequency of cool nights(days) has decreased by 2.45 days/decade(0.86 days/decade),whereas the frequency of warm nights(days) has increased by 4.85 days/decade(1.62 days/decade).Seasonally,the frequencies of summer warm nights and days are changing more rapidly than the corresponding frequencies for cool nights and days.However,normalization of the extreme and mean series shows that the rate of changes in extreme temperature events are generally less than those of mean temperatures,except for winter cold nights which are changing as rapidly as the winter mean minimum temperatures.These results indicate that there have been seasonally and diurnally asymmetric changes in extreme temperature events relative to recent increases in temperature means in Xinjiang. | YanWei Zhang WenShou Wei FengQing Jiang MingZhe Liu WenWen Wang Lei Bai KaiFeng Li Rui Shao ZhiWen Dong | 2012 | Research in Cold and Arid Regions2012，4，1： | 4 |

| 10 | Research on the disappearance causes of the Tenghualuo Site in Lianyungang,Jiangsu Province, China显示文摘With brilliant civilization during the transitional period from a original clan society to a state society in prehistory,the Neolithic Tenghualuo Site in Lianyungang was discovered by archaeological survey in 1989,which was titled as‘one of the nation’s ten great archeological discoveries in 2000’.However,the transgression and the anthropogenic environment deterioration have ever been employed to explain the abandonment of the site.Based on a dynasty framework established by the 14 C dating,and using the experimental methods such as micro-paleontology identification in foraminifera and charophytes, the content test of Rb and Sr,susceptibility analysis as well as granularity and sedimentary facies analysis,some researches on the sediments from the two exploration layers at Tenghualuo Site were conducted,and the following new findings have been gained:Firstly,foraminifera which are relevant to the marine environment were not found in the sediment layer,however,25 charales,which usually live in the freshwater environment,in 07LTT1 exploration samples were found.Among them,3 charales were found in the samples from the forth sediment layer below the late Longshan Cultural layer and 22 charates were from the second sediment layer above the late Longshan Cultural layer.Furthermore,5 plant seeds and 41 fungal spores,together with many carbonation holes,plant seed shells,as well as their roots and stems were also found in the second sediment layer above the late Longshan Cultural layer.Secondly,the cumulative probability curves of the sediments’granularity in both the last and its overlying culture intermittent layers have characteristics of three-phase river sediment curve,and the ratios between Rb and Sr are both quite high in samples from two layers sedimented during the disappearing time of the site.All above-mentioned evidences indicate that disappearance of the Tenghualuo Site was not related to the transgression.The late Longshan Culture of the site could be completely abandoned after a relatively long-term inland water flood. | LI Lan ZHU Cheng JIANG FengQing ZHAO QuanHong LIN liuGeng | 2008 | Chinese Science Bulletin2008，53，S1： | 3 |
| 11 | Auxin response factor 6A regulates photosynthesis,sugar accumulation,and fruit development in tomato显示文摘Auxin response factors(ARFs)are involved in auxin-mediated transcriptional regulation in plants.In this study,we performed functional characterization of SlARF6A in tomato.SlARF6A is located in the nucleus and exhibits transcriptional activator activity.Overexpression of SlARF6A increased chlorophyll contents in the fruits and leaves of tomato plants,whereas downregulation of SlARF6A decreased chlorophyll contents compared with those of wild-type(WT)plants.Analysis of chloroplasts using transmission electron microscopy indicated increased sizes of chloroplasts in SlARF6A-overexpressing plants and decreased numbers of chloroplasts in SlARF6A-downregulated plants.Overexpression of SlARF6A increased the photosynthesis rate and accumulation of starch and soluble sugars,whereas knockdown of SlARF6A resulted in opposite phenotypes in tomato leaves and fruits.RNA-sequence analysis showed that regulation of SlARF6A expression altered the expression of genes involved in chlorophyll metabolism,photosynthesis and sugar metabolism.SlARF6A directly bound to the promoters of SlGLK1,CAB,and RbcS genes and positively regulated the expression of these genes.Overexpression of SlARF6A also inhibited fruit ripening and ethylene production,whereas downregulation of SlARF6A increased fruit ripening and ethylene production.SlARF6A directly bound to the SAMS1 promoter and negatively regulated SAMS1 expression.Taken together,these results expand our understanding of ARFs with regard to photosynthesis,sugar accumulation and fruit development and provide a potential target for genetic engineering to improve fruit nutrition in horticulture crops. | Yujin Yuan Xin Xu Zehao Gong Yuwei Tang Mengbo Wu Fang Yan Xiaolan Zhang Qian Zhang Fengqing Yang Xiaowei Hu Qichen Yang Yingqing Luo Lihua Mei Wenfa Zhang Cai-Zhong Jiang Wangjin Lu Zhengguo Li Wei Deng | 2019 | Horticulture Research2019，6，1： | 3 |

| 13 | Timing of the terrestrial Permian-Triassic boundary biotic crisis:Implications from U-Pb dating of authigenic zircons显示文摘The Late Permian to Early Triassic transition represents one of the most important Phanerozoic mass extinction episodes. The cause of this event is still in debate between catastrophic and gradual mechanisms. This study uses the U-Pb method on zircons from the uppermost Permian/lowermost Triassic clay deposits at Chahe (Guizhou Province, SW China) to examine time constraints for this event. The results of both this and previous studies show that the ages of Bed 68a and 68c (the upper clay bed of the terrestrial Permian-Triassic boundary (PTB)) respectively are 252.6±2.8 and 247.5±2.8 Ma. This age (within the margin of error) almost accords with the upper clay bed (Bed 28) age of Meishan and the eruption age of Tunguss Basalt, and is so far the most accurate age obtained from terrestrial PTB. The claystone of Bed 68 was formed in the earliest Triassic. The biotic crisis occurred at nearly the same time in terrestrial and marine environments during Permian-Triassic interval; however the extinction patterns and processes are different. The extinction pattern of the terrestrial plants shows a major decline at the PTB after long-term evolution, followed by a retarded extinction of the relicts in the earliest Triassic. | YU JianXin LI HuiMin ZHANG SuXin YANG FengQing FENG QingLai | 2008 | Science China Earth Sciences2008，51，11： | 2 |

| 16 | Interaction-Aware Cut-In Trajectory Prediction and Risk Assessment in Mixed Traffic显示文摘Accurately predicting the trajectories of surrounding vehicles and assessing the collision risks are essential to avoid side and rear-end collisions caused by cut-in.To improve the safety of autonomous vehicles in the mixed traffic,this study proposes a cut-in prediction and risk assessment method with considering the interactions of multiple traffic participants.The integration of the support vector machine and Gaussian mixture model(SVM-GMM)is developed to simultaneously predict cut-in behavior and trajectory.The dimension of the input features is reduced through Chebyshev fitting to improve the training efficiency as well as the online inference performance.Based on the predicted trajectory of the cut-in vehicle and the responsive actions of the autonomous vehicles,two risk measurements are introduced to formulate the comprehensive interaction risk through the combination of Sigmoid function and Softmax function.Finally,the comparative analysis is performed to validate the proposed method using the naturalistic driving data.The results show that the proposed method can predict the trajectory with higher precision and effectively evaluate the risk level of a cut-in maneuver compared to the methods without considering interaction. | Xianglei Zhu Wen Hu Zejian Deng Jinwei Zhang Fengqing Hu Rui Zhou Keqiu Li Fei-Yue Wang | 2022 | IEEE/CAA Journal of Automatica Sinica2022，9，10： | 2 |
