本文根据流域规划中已于1980年底建成的工程进行环境影响评价,并据以预估流域规划工程全部投产后对环境的影响。一、水利水电工程对环境要素的影响(一)对自然环境的影响1.物理化学方面(1)水文情势已经建成的蓄水工程,共控制集水面积16,212平方公里,均在不同程度上、不同范围内蓄滞洪水、削减洪峰,增加枯水流量。其中以新丰江和枫树坝削减
Based on the project completed in the end of 1980 in the river basin planning, the EIA is carried out and the impact on the environment after the river basin planning project is fully put into operation is estimated. I. Influence of Water Conservancy and Hydropower Engineering on Environmental Factors (I) Impact on the Natural Environment 1. Physical and Chemical Aspects (1) Hydrological situation The water storage project has been completed and a total catchment area of 16,212 square kilometers has been controlled, all of which, to varying degrees, Detention of floods in different areas, cut floods, increase dry flow. Among them, the Xinfengjiang and Maple Dam cut
