| 1 | 葛洲坝水利枢纽工程截流后长江四大家鱼产卵场调查显示文摘本文报道了葛洲坝水利枢纽工程截流后长江四大家鱼产卵场情况。调查结果表明,长江干流上、中游四大家鱼产卵场的地理分布同60年代的调查结果基本相同。但其产卵总量仅为60年代调查结果的15.7%,资源量已严重衰减。产卵成色同60年代调查资料比较,草鱼和青鱼的比例显著增大,鳙鱼比例略有降低,而鲢鱼的比例显著下降。生殖群体结构已呈现简化(破坏),亲鱼个体变小,年龄组限减少,低龄鱼占群体数量的主导地位,初次性成熟的个体比重较大。调查表明,目前葛洲坝以上江段家鱼产卵数量占总量的36.4%,因此,在长江家鱼资源状况严重恶化的情况下,葛洲坝以上产卵场的地位就益显重要。鉴于葛洲坝水利枢纽工程阻隔了洄游生殖鱼类上溯产卵通道,葛洲坝应尽快修建过鱼设施,使草鱼等洄游性鱼类得以过坝上溯产卵,以保护或扩大四大家鱼及其他经济鱼类的资源。 | Survey Team of Spawning Grounds of Domestic Fishes in Chanjiang River | 1982 | 水产学报1982，6，4： | 74 |
| 2 | Analysis on the ecological benefits of the stream water conveyance to the dried-up river of the lower reaches of Tarim River,China显示文摘This paper analyzes the monitored data of the 4 times of stream water conveyances to the river section where the stream flow was cut-off, of 9 groundwater-monitoring sections and 18 vegetation plots in the lower reaches of Tarim River. The results show that the groundwater depth in the lower reaches of Tarim River rose from 9.87 m before the conveyances to 7.74 m and 3.79 m after the first and second conveyances, 3.61 and 3.16 m after the 2 phases of the third conveyance, and 2.66 m after the fourth conveyance. The transverse response scope of groundwater level was gradually enlarged along both sides of the channel of conveyances, i.e., from 450 m in width after the first conveyance to 1050 m after the fourth conveyance, but the response degree of groundwater level was reduced with the increase of the distance away from the channel of conveyances. The composition, distribution and growth status of the natural vegetation are directly related to the groundwater depth. The indexes of Simpson’s biodiversity, McIntosh’s evenness and Margalef’s richness, which reflect the change of the quantity of species and the degree of biodiversity, are reduced from 0.70, 0.48 and 0.90 to 0.26, 0.17 and 0.37 re- spectively along with the drawdown of groundwater level from the upper reaches to the lower reaches. After the stream water conveyances, the natural vegetation in the lower reaches is saved and restored along with the rise of groundwater level, the response scope of vegetation is gradually enlarged, i.e., from 200— 250 m in width after the first conveyance to 800 m after the fourth conveyance. However, there is still a great disparity to the objective of protecting the “Green Corridor”in the lower reaches of Tarim River. Thus, it is suggested to convey the stream water in double-channel way, combine the conveyance with water supply in surface scope, or construct the modern pipe-conveyance network systems so as to save the natural vegetation in an intensive way, achieve the efficient water consumption and speed up the restoration and re- generation of the damaged ecosystems in the lower reaches of Tarim River. | CHEN Yaning1,ZHANG Xiaolei1,ZHU Xiangmin2,LI Weihong1,ZHANG Yuanming1,XU Hailiang1,ZHANG Hongfeng1 & CHEN Yapeng1 1.Xinjiang Institute of Ecology and Geography,Chinese Academy of Sciences,Urumqi 830011,China 2.Management Beureau od Tarim River Basin,Kurle 831102,China Correspondence should be addressed to Chen Yaning(email: cheyn@ms.xjb.ac.cn) | 2004 | Science China Earth Sciences2004，47，11： | 58 |
| 3 | Effect of proteins,polysaccharides,and particle sizes on sludge dewaterability显示文摘Four batch experiments of hydrolysis and acidification were carried out to investigate the distributions of proteins(PN) and polysaccharides(PS) in the sludge,the PN/PS ratio,the particle sizes,and their relationship with sludge dewaterability(as determined by capillary suction time,CST) . The sludge flocs were stratified through centrifugation-and ultrasound-based method into four fractions:(1) slime,(2) loosely bound extracellular polymeric substances(LB-EPS) ,(3) tightly bound EPS(TB-EPS) ,and(4) pellet. The results showed that PN was mainly partitioned in the pellet(80.7%) and TB-EPS(9.6%) fractions,while PS distributed evenly in the four fractions. During hydrolysis and acidification,PN was transferred from the pellet and TB-EPS fractions to the slime fraction,but PS had no significant transfer trends. The mean particle sizes of the sludge flocs decreased with hydrolysis and acidification. The pH had a more significant influence on the dewaterability of sludge flocs than temperature. Sludge dewaterability during hydrolysis and acidification processes greatly deteriorated from 9.7 s at raw sludge to 340-450 s under alkaline conditions. However,it was just slightly increased under acidic conditions. Further investigation suggested that CST was affected by soluble PN,soluble PN/PS,and particle sizes of sludge flocs,but was affected slightly by total PN,PS,or PN/PS in the whole sludge flocs and other fractions(except slime) . | SHAO Liming,HE Peipei,YU Guanghui,HE Pinjing State Key Laboratory of Pollution Control and Resources Reuse,Key Laboratory of Yangtze River Water Environment,College of Environmental Science and Engineering,Tongji University,Shanghai 200092,China | 2009 | Journal of Environmental Sciences2009，21，1： | 37 |
| 4 | A study of interaction between surface water and groundwater using environmental isotope in Huaisha River basin显示文摘The surface water and groundwater are important components of water cycle, and the interaction between surface water and groundwater is the important part in water cycle research. As the effective tracers in water cycle research, environmental isotope and hydrochemistry can reveal the interrelationships between surface water and groundwater effectively. The study area is the Huaisha River basin, which is located in Huairou district, Beijing. The field surveying and sampling for spring, river and well water were finished in 2002 and 2003. The hydrogen and oxygen isotopes and water quality were measured at the laboratory. The spatial characteristics in isotope and evolution of water quality along river lines at the different area were analyzed. The altitude effect of oxygen isotope in springs was revealed, and then using this equation, theory foundation for deducing recharge source of spring was estimated. By applying the mass balance method, the annual mean groundwater recharge rate at the catchment was estimated. Based on the groundwater recharge analysis, combining the hydrogeological condition analysis, and comparing the rainfall-runoff coefficients from the 1960s to 1990s in the Huaisha River basin and those in the Chaobai River basin, part of the runoff in the Huaisha River basin is recharged outside of this basin, in other words, this basin is an un-enclosed basin. On the basis of synthetically analyses, combining the compositions of hydrogen and oxygen isotopes and hydrochemistry, geomorphology, geology, and watershed systems characteristics, the relative contributions between surface water and groundwater flow at the different areas at the catchments were evaluated, and the interaction between surface water and groundwater was re- vealed lastly. | SONG Xianfang1, LIU Xiangchao1, 2, XIA Jun1, YU Jingjie1 & TANG Changyuan1, 3 1.

| 5 | Numerical simulation of air-water two-phase flow over stepped spillways显示文摘Stepped spillways for significant energy dissipation along the chute have gained interest and popularity among researchers and dam engineers. Due to the com- plexity of air-water two-phase flow over stepped spillways, the finite volume computational fluid dynamics module of the FLUENT software was used to simulate the main characteristics of the flow. Adopting the RNG k-ε turbulence model, the mixture flow model for air-water two-phase flow was used to simulate the flow field over stepped spillway with the PISO arithmetic technique. The numerical result successfully reproduced the complex flow over a stepped spillway of an experiment case, including the interaction between entrained air bubbles and cavity recirculation in the skimming flow regime, velocity distribution and the pressure profiles on the step surface as well. The result is helpful for under-standing the detailed information about energy dissipation over stepped spillways. | CHENG Xiangju1, CHEN Yongcan1 & LUO Lin2 1.

| 6 | Role of soil rhizobacteria in phytoremediation of heavy metal contaminated soils显示文摘Heavy metal pollution of soil is a significant environmental problem and has its negative impact on human health and agriculture. Rhizosphere, as an important interface of soil and plant, plays a significant role in phytoremediation of contaminated soil by heavy metals, in which, microbial populations are known to affect heavy metal mobility and availability to the plant through release of chelating agents, acidification, phosphate solubilization and redox changes, and therefore, have potential to enhance phytoremediation processes. Phytoremediation strategies with appropriate heavy metal-adapted rhizobacteria have re-ceived more and more attention. This article paper reviews some recent advances in effect and significance of rhizobacteria in phytoremediation of heavy metal contaminated soils. There is also a need to improve our understanding of the mechanisms in-volved in the transfer and mobilization of heavy metals by rhizobacteria and to conduct research on the selection of microbial isolates from rhizosphere of plants growing on heavy metal contaminated soils for specific restoration programmes. | JING Yan-de1,2, HE Zhen-li1,3, YANG Xiao-e1 (1Ministry of Education Key Lab of Environment, Remediation and Ecosystem Health, School of Natural Resource and Environment Science, Zhejiang University, Hangzhou 310029, China) (2Department of Resources and Planning, Qufu Normal University, Jining 273165, China) (3University of Florida Institute of Food and Agricultural Sciences, Indian River Research and Education Center, Fort Pierce, Florida 34945, USA) | 2007 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2007，8，3： | 18 |
| 7 | Regional differences and determinants of built-up area expansion in China显示文摘Based on remote sensing data on land use provided by the Chinese Academy of Sciences and socio-economic data collected by the authors,this paper analyzes the trends and regional differences in built-up area(BUA) expansion in China from the late 1980s to 2000,and empirically estimates the major determinants of BUA expansion in different regions in 1996―2000.In 1989―2000,although China's overall BUA expansion accelerated,the trends differed significantly among regions.BUA expansion in the central and western regions accelerated significantly,but it slowed down considerably in the east-ern region.The estimation results from our econometric analysis reveal that BUA expansion in the eastern region reached a period when economic growth had no further significant impact on per capita BUA,the land utilization in this region has become more intensive with further expansion of the economy.In the central and western regions,the BUA has expanded remarkably due to the relatively more flexible land development policies and the relatively cheap land prices.Therefore,as the econ-omy continues to grow rapidly,policies relating to BUA expansion and cultivated land reductions may face more serious challenges in the central and western regions. | HUANG JiKun1,2,ZHU LiFen3,1 & DENG XiangZheng1,2 1 Center for Chinese Agricultural Policy,Chinese Academy of Sciences,Beijing 100101,China 2 Institute of Geographic Sciences and Natural Resources Research,Chinese Academy of Sciences,Beijing 100101,China 3 Research Center of the Economy of the Upper Reaches of the Yangtze River,Chongqing Technology and Business University,Chongqing 400067,China | 2007 | Science China Earth Sciences2007，50，12： | 17 |
| 8 | Simulation of influence of multi-defects on long-term working performance of high arch dam显示文摘As an integrated structure,an arch dam is assumed to bear loads in its design consideration.However,multi-defects,such as cracks and the opening of transverse joints,are unavoidable during construction and operation.Multi-defects will reduce the structural integrity and stiffness of the dam and affect its working performance and degree of safety.In the current paper,a numerical model of defects and a simulation method of a high arch dam are introduced.The Chencun arch dam is analyzed as a case study.An entire course simulation analysis of the Chencun arch dam from construction to operation is carried out,through which the opening of the transverse and longitudinal joints,formation of cracks,and their influence on deformation and stress of the dam are studied.According to the results of the analysis,appropriate measures should be adopted to prevent the development of cracks,and observation should be strengthened for a more timely discovery of risks. | ZHANG GuoXin ,LIU Yi,ZHENG CuiYing & FENG Fan State Key Laboratory of Simulation and Regulation of Water Cycle in River Basin,Beijing 100038,China China Institute of Water Resources and Hydropower Research,Beijing 100038,China | 2011 | Science China(Technological Sciences)2011，54，S1： | 17 |

| 10 | A LINEAR THEORY FOR DISTURBANCE OF COHERENT STRUCTURE AND MECHANISM OF SAND WAVES IN OPEN-CHANNEL FLOW显示文摘The formation of sand wave is such a process in which the roughness and discontinuity of the original bed surface cause the disturbance of the bottom laminar flow in an open channel, and the development of the disturbance in turn leads to instability of the flow and the appearance of the coherent structure. The evolution and development of the coherent structure further promote the undulations of bed surface and sand waves rise finally. The sand wave is explained as a result of action that the bed sediment particles are disturbed by the coherent structure. This study shows that the sand wave formation is the result of disturbance action of neutral coherent structure, and the sand wave shape obtained in computations is identical to the practical one. | Yuchuan BAI1, Andreas MALCHEREK2 and Changbo JIANG 1 Institute for Sedimentation on River and Coast Engineering, Tianjin University, Tianjin 300072, China.

| 11 | A MATHEMATICAL MODEL FOR UNSTEADY SEDIMENT TRANSPORT IN THE LOWER YELLOW RIVER显示文摘A one-dimensional mathematical model for unsteady sediment transport in the Lower Yellow River is developed. A coefficient of sediment distribution is defined to represent the ratio of the bottom to the average concentration under the equilibrium conditions. The coefficient is not constant and is evaluated by using an empirical expression obtained by integrating the sediment concentration along water depth. The concentration distributions and the mean diameter distributions of suspended sediment in the transversal direction are also estimated in this model. A four-point (Preismann type) finite difference scheme and TDMA are employed in the numerical method. Three typical floods occurd in 1977,1982 and 1996, respectively, in the Lower Yellow River from Tiexie to Shunkou with a length of 393.67km are numerically simulated with the model. The computed results, such as the water stage, discharge, and sediment concentration agree well with the measured data. | ZHANG Hongwu1, HUANG Yuandong1 and ZHAO Lianjun2 1 Department of Hydraulic Engineering, Tsinghua University, Beijing 100084, China 2 Yellow River Institute of Hydraulic Research, Zhengzhou 450003, China | 2001 | International Journal of Sediment Research2001，16，2： | 13 |
| 12 | Release of volatile organic compounds during bio-drying of municipal solid waste显示文摘Three treatments were tested to investigate the release concentrations of volatile organic compounds (VOCs) during the bio-drying of municipal solid waste (MSW) by the aerobic and combined hydrolytic-aerobic processes.Results showed that VOCs were largely released in the first 4 days of bio-drying and the dominant components were:dimethyl disulfide,dimethyl sulfide,benzene,2-butanone,limonene and methylene chloride.Thus,the combined hydrolytic-aerobic process was suggested for MSW bio-drying due to fewer aeration quantities in this phase when compared with the aerobic process,and the treatment strategies should base on the key properties of these prominent components.Malodorous sulfur compounds and terpenes were mainly released in the early phase of bio-drying,whereas,two peaks of release concentrations appeared for aromatics and ketones during bio-drying.Notably,for the combined hydrolytic-aerobic processes there were also high concentrations of released aromatics in the shift from hydrolytic to aerobic stages.High concentrations of released chlorinateds were observed in the later phase.For the VOCs produced during MSW bio-drying,i.e.,malodorous sulfur compounds,terpenes and chlorinateds,their release concentrations were mainly determined by production rates;for the VOCs presented initially in MSW,such as aromatics,their transfer and transport in MSW mainly determined the release concentrations. | Pinjing He,Jiafu Tang,Dongqing Zhang,Yang Zeng,Liming ShaoState Key Laboratory of Pollution Control and Resource Reuse,Key Laboratory of Yangtze River Water Environment,College of Environmental Science and Engineering,Tongji University,Shanghai 200092,China. | 2010 | Journal of Environmental Sciences2010，22，5： | 13 |

| 14 | A new type of plunge pool―Multi-horizontal submerged jets显示文摘Based on the understanding of the mechanism of energy dissipation,a new type of plunge pool is presented with the advantages of high rate of energy dissipation,low impact pressure,and small close-to-bed velocity on the soleplate of the plunge pool.The first advantage owes to enlarged shearing energy dissipation areas in the plunge pool,while the other two are caused by the jet that enters in a nearly horizontal level to keep the soleplate from being scoured directly.All of the above arrangements make this new type of energy dissipator distinct from the underflow energy dissipation.Through experiments on the physical model,the authors found that the water flow maintained stable and submerged in horizontal direction when the flow was narrow in horizontal but thick in vertical direction.However,the wide flat nappe was ready to submerge or float as the downstream water level rised or dropped.The entire flow fields of multi-horizontal submerged jets into plunge pool were also numerically simulated.The numerical results of water surface curve,close-to-bed velocity and floor pressure agree well with the experimental data.The flow pattern in the plunge pool was analyzed after combining the laboratory data and numerical simulation. | DENG Jun,XU WeiLin,ZHANG JianMing,QU JinXue & YANG YongQuan State Key Laboratory of Hydraulics and Mountain River Engineering,Sichuan University,Chengdu 610065,China | 2008 | Science China(Technological Sciences)2008，51，12： | 12 |
| 15 | Thermal stabilization of chromium slag by sewage sludge: Effects of sludge quantity and temperature显示文摘To investigate the feasibility of detoxifying chromium slag by sewage sludge,synthetic chromium slag containing 3% of Cr(VI) was mixed with sewage sludge followed by thermal treatment in nitrogen gas for stabilizing chromium.The effects of slag to sludge ratio(0.5,1 and 2) and temperature(200,300,500,700 and 900°C) on treatment efficiency were investigated.During the mixing process before thermal treatment,59.8%-99.7% of Cr(VI) was reduced,but Cr could be easily leached from the reduction product.Increasing heating temperature and decreasing slag to sludge ratio strengthened the reduction and stabilization of Cr(VI).When the slag to sludge ratio was 0.5 and thermal treatment temperature was 300°C,the total leached Cr and Cr(VI) declined to 0.55 mg/L and 0.17 mg/L respectively,and 45.5% of Cr in the thermally treated residue existed as residual fraction.A two-stage mechanism was proposed for the reduction and stabilization of Cr. | Changlin Wu,Hua Zhang,Pinjing He,Liming Shao State Key Laboratory of Pollution Control and Resources Reuse,Key Laboratory of Yangtze River Water Environment,College of Environmental Science & Engineering,Tongji University,Shanghai 200092,China. | 2010 | Journal of Environmental Sciences2010，22，7： | 11 |
| 16 | Soil erosion and sediment transport in the gullied Loess Plateau:Scale effects and their mechanisms显示文摘Scale effects exist in the whole process of rainfall―runoff―soil erosion―sediment transport in river basins.The differences of hydrographs and sediment graphs in different positions in a river basin are treated as basic scale effects,which are more complex in the gullied Loess Plateau,a region notorious for high intensity soil erosion and hyper-concentrated sediment-laden flow.The up-scaling method of direct extrapolation that maintains dynamical mechanism effective in large scale application was cho-sen as the methodology of this paper.Firstly,scale effects of hydrographs and sediment graphs were analyzed by using field data,and key sub-processes and their mechanisms contributing to scale effects were clearly defined.Then,the Digital Yellow River Model that integrates sub-models for the sub-processes was used with high resolution to simulate rainfall―runoff―soil erosion―sediment transport response in Chabagou watershed,and the distributed results representing scale effects were obtained.Finally,analysis on the simulation results was carried out.It was shown that gravitational erosion and hyper-concentrated flow contribute most to the spatial variation of hydrographs and sediment graphs in the spatial scale.Different spatial scale distributions and superposition of different sub-processes are the mechanisms of scale effects. | LI TieJian1,WANG GuangQian1,XUE Hai2,3 & WANG Kai4 1 State Key Laboratory of Hydroscience and Engineering,Tsinghua University,Beijing 100084,China 2 Yellow River Engineering Consulting Co.,Ltd.,Zhengzhou 450003,China 3 North China Institute of Water Conservancy and Hydropower,Zhengzhou 450008,China 4 China Institute of Water Resources and Hydropower Research,Beijing 100038,China | 2009 | Science China(Technological Sciences)2009，52，5： | 11 |
| 17 | Study on the changes of water cycle and its impacts in the source region of the Yellow River显示文摘The water cycle in the source region of the Yellow River underwent great changes in the 1990s. The major features of the changes are as follows: the gauged runoff declined significantly while the precipitation increased slightly, and the runoff process was more concentrated on the flood season. Water balance analyses indicate that the pondage was kept in the status of negative equilibrium, causing eco-environmental problems. The runoff decrement is due to evaporation increment in this region. Studies show that the runoff process in this region is closely related to that of the other hydrological stations in the upper reaches. When the runoff declines in the source regions, the amount of water also declines in the whole upper reaches of the Yellow River, affecting the balance between water demand and supply. Meanwhile changes will take place in the water cycle of the river course system when the eco-environment deteriorates. The trend of water cycle change in the source region is that the runoff will keep declining with the increment of evaporation caused by temperature rise in the northwest of China in the 21st century. But the hydraulic engineering in the source region will help to mitigate the deterioration of local eco-environment system, though the impacts to the lower reaches of this project may not be the case. | ZHANG Shifeng1, JIA Shaofeng1, LIU Changming1, CAO Wenbing2, HAO Fanghua3, LIU Jiuyu4 & YAN Huayun5 1.
