鄱阳湖水利枢纽工程对湖泊水位与面积关系的影响分析
作者: 熊家庆  来源:江西师范大学 年份:2015 文献类型 :学位论文 关键词: 鄱阳湖水利枢纽工程  水位  鄱阳湖  面积  EFDC模型 
描述:背景,分析鄱阳湖水利枢纽工程对湖泊水位与面积关系的影响。得出本文主要研究结论如下:(1)在无水利枢纽工程时,都昌站在枯、平、丰年的湖泊水位与湖面面积关系中表现较好。因此,选择都昌站作为鄱阳湖

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.
