摘　　要：乌东德水电站位于金沙江干流下游,工程产生巨大效益的同时也将对环境带来一定不利影响,主要包括水库蓄水引起水文情势变化以及大坝阻隔、低温水下泄对鱼类生境的影响;水库淹没和工程占地对陆生生态的影响;建库后水流变缓,对水库支流回水区域以及库尾攀枝花河段近岸水域水质产生影响;工程施工产生的"三废"和噪声以及移民安置对周边环境产生一定影响。针对工程建设可能产生的不利影响,提出了相关的环境保护对策措施。Wudongde Hydropower Station is located on the lower reach of Jinsha River. The project will generate huge econom- ic benefit, but at the same time, it will bring about a certain impact on the environment, mainly including hydrologic regime change induced by the reservoir impoundment, the impact on fish habitat due to dam barrier and low temperature flow discharge, the impact on terrestrial ecosystems by inundation and land occupation; the impact on water quality near the bank in backwater area of tributaries and tail area of the reservoir due to low velocity flow ; the impact on the surrounding area by ＂3 wastes＂ and noise produced during project construction and resettlement. In the light of the unfavorable impacts possibly occurred in the con- struction, the correlative environmental protection measures are put forward.
