【摘要】 从水环境的角度分析三峡工程对洞庭湖的影响,研究三峡工程建成后洞庭湖的水环境容量、淤沙变化、化学特征、生态环境变化,提出三峡工程建成后对洞庭湖水环境的影响主要有三方面:①枯水期增泄流量及洪水期减泄流量对水生动植物的影响;②水库拦蓄泥沙对淤积的影响;③对水质的影响。更多还原

【Abstract】 From the angle of water environment, an analysis was made on the water environment capacity, variation of sedimentation and ecological environment, and chemical characteristics of Dongting Lake after the completion of the Three Gorges Project. It is concluded that the influences mainly concentrate in three aspects: the influences of the volume of flood discharge increased in the low-water season and the volume of flood discharge decreased in the flood season on the aquatic lives, the influence of sediment retention on sedimentation, and the influence on the water quality of the lake.更多还原
