Research on Ecological Effects of Reservoir Dam Project

Abstract

Ecological effects of dam and reservoir development is a new concept proposed in recent years. It refers to the ecological impact and ecological consequences in the dam construction and operation process, which not only including the positive ecological effects, but also the negative. Ecological effect analysis is a kind of analysis which pointed at the influence of the water conservancy projects built on the living environment, the impact of the wild animals and plants, the effect of natural law, the impact of the economic growth. Based on the analysis of previous research results, this paper summarizes the connotation and characteristics of the ecological effects of the reservoir and dam project, and analyzes the ecological effects of the reservoir and dam project from the aspects of Hydrology, water environment, biology, climate, etc., this paper summarizes the connotation and characteristics of the ecological effect of the reservoir dam project, and provides the scientific basis for whether the hydraulic engineering should be retained or whether the function should be improved.
