【摘要】：为全面了解梯级水库建设的水环境累积影响,从水环境累积影响的定义、分类和特征三方面对其进行了总结,介绍了目前水环境累积影响研究的常用方法,着重归纳了梯级开发对径流、水质、水温和泥沙等水环境累积影响的研究成果,指出了各方面的影响范围和主要特征,探讨了梯级水库水环境累积影响研究的新趋势。我国梯级水库水环境累积影响研究处于发展阶段,目前的研究多集中于定性评价,急需建立统一的评价标准和评价方法,系统地认识梯级水库建设的环境效应。
[Abstract]:In order to understand the cumulative impact of water environment in cascade reservoir construction, this paper summarizes the definition, classification and characteristics of the cumulative impact of water environment, and introduces the methods commonly used to study the cumulative impact of water environment at present. The research results of cascade development on the accumulative effects of runoff, water quality, water temperature and sediment on water environment are summarized, and the influence range and main characteristics of each aspect are pointed out. This paper discusses the new trend of the research on the cumulative impact of cascade reservoirs on water environment. The research on the cumulative impact of cascade reservoirs in China is in the stage of development, and most of the current studies are focused on qualitative evaluation, so it is urgent to establish a unified evaluation standard and evaluation method. The environmental effects of cascade reservoir construction are systematically recognized.
