描述：Since the construction of the Three Gorges Dam,the Poyang Lake hydrological characteristics obviously changed.During the impoundment period of the Three Gorges Reservoir,the hydrodynamic factors of Poyang Lake varied.Water level dropped,the velocity decreased and water exchange time lengthened,which changed the release of phosphorous from sediments.In order to investigate how the hydrodynamic factors influence the release of phosphorous from sediments,we used a two-way annular flume device to simulate the release characteristics of phosphorous from sediments under variable water levels and velocities.We found that both water level rising and velocity increasing could enhance the disturbance intensity to sediments,which caused the increase of suspended solids(SS)concentration,total phosphorus(TP)concentration in the overlying water,and the ability that phosphorus released to overlying water from sediments enhanced as well:when overlying water velocity maintained 0.3 m/s,SS concentration increased to 4035.85 mg/L at the water level25 cm which was about 25 times compared to the minimum value and TP concentration in the overlying water also reached the maximum value at the water level 25 cm which was 1.2times that of the value at 10 cm;when water level maintained 15 cm,SS concentration increased to 4363.35 mg/L at the velocity of 0.5 m/s which was about 28 times compared to the value of 0 m/s,and TP concentration in the overlying water increased from 0.11 mg/L to 0.44mg/L.When the water level maintained 15 cm,the phosphorous release rate reached the maximum value of 4.86 mg/(md)at 0.4 m/s.The concentration of total dissolved phosphorous(TDP)and soluble reactive phosphate(SRP)both in overlying water and sediment-water interface were negatively correlated with p H.Using the parabolic equation,the optimum water level at a velocity of 0.3 m/s was calculated to be 0.57 cm,and the optimum velocity at water level of 15 cm was found to be 0.2 m/s.

鄱阳湖水文特性分析

作者： 徐德龙 熊明 张晶  来源：人民长江 年份：2002 文献类型 ：期刊 关键词： hydrologic  composition  Poyang  property  action  Lake  storage  flood 

描述：The Poyang lake is currently the largest freshwater lake in China. Hydrologic properties of this lake, including precipitation, runoff, flood, sediment transport and so on have been analyzed on basis of large amount of measurements. Variation of these properties within a year and among years and the regional distribution are explored. The encounter probability of the outflow from Poyang Lake with that from Changjiang River is computed and the detention volume of Poyang Lake is analyzed. In accordance with water balance theory, the detention storage volume of Poyang Lake and Changjiang River corresponding to the annual maximum 60-day flood volumes in 9 typical heavy flood years of 1968, 1969, 1973, 1980, 1983, 1996 and 1998 have been calculated. The detention storage capacity of both the Lake and the River ranges from 5.6 billion to 16.5 billion m\+3, 11.5 billion m\+3 at average. Among which, the detention storage capacity of Poyang Lake is 9.5 billion m\+3, accounting for 82.6%. Poyang Lake has played a very important role in detaining floods from the five rivers of the Lake system as well as floods on the river section from Changjiang to Bali. There would have more frequent and more serious flooding on the middle and lower Changjiang River, especially in the region around Hukou if there were no Poyang Lake to detain and store the floodwater.

鄱阳湖非平稳水位波动及其与长江的交互作用关系

作者： 戴雪 万荣荣 杨桂山  来源：地理学报(英文版) 年份：2015 文献类型 ：期刊 关键词： Yangtze  earlier  seasonal  intensified  downstream  lacustrine  river  representative  flood  dominate 

描述：Seasonal water-level fluctuations(WLF) play a dominate role in lacustrine ecosystems. River-lake interaction is a direct factor in changes of seasonal lake WLF, especially for those lakes naturally connected to upstream and downstream rivers. During the past decade, the modification of WLF in the Poyang Lake(the largest freshwater lake in China) has caused intensified flood and irrigation crises, reduced water availability, compromised water quality and extensive degradation of the lake ecosystem. There has been a conjecture as to whether the modification was caused by its interactions with Yangtze River. In this study, we investigated the variations of seasonal WLF in China’s Poyang Lake by comparing the water levels during the four distinct seasons(the dry season, the rising season, the flood season, and the retreating season) before and after 2003 when the Three Gorge Dam operated. The Water Surface Slope(WSS) was used as a representative parameter to measure the changes in river-lake interaction and its impacts on seasonal WLF. The results showed that the magnitude of seasonal WLF has changed considerably since 2003; the seasonal WLF of the Poyang Lake have been significantly altered by the fact that the water levels both rise and retreat earlier in the season and lowered water levels in general. The fluctuations of river-lake interactions, in particular the changes during the retreating season, are mainly responsible for these variations in magnitude of seasonal WLF. This study demonstrates that WSS is a representative parameter to denote river-lake interactions, and the results indicate that more emphasis should be placed on the decrease of the Poyang Lake caused by the lowered water levels of the Yangtze River, especially in the retreating season.
