| Hydropower has made a great progress ever since our country has been built up, and promotes rapid-increasing, sustainable and healthy development of national economy effectively. However, with increasing consciousness for ecological protection, the public pay more attention on negative impact caused by hydropower project. So how to coordinate the relationship between hydropower project and ecological environment, and how to manage the whole constructing process of hydropower project, will be key issues of environmental impact assessment and environmental management about hydropower project in the future.On the basis of related document and case stu3dying, this paper takes Wulong mountain pumped storage power project as an example to study the impact assessment and eco-management for terrestrial ecological environment in hydropower project. The main conclusions of this paper are listed below:(1) The aim for eco-environmental impact assessment of hydropower project is to balance construction of hydropower project and eco-environment protection; methods which are drawn up to protect eco-environment and eco-environment management system based on eco-environmental impact assessment ensure coordination between construction of hydropower project with eco-environment protection and implement of measures for eco-environment protection.(2) Taking integrity of eco-system as standard, eco-environment impact analysis and assessment for hydropower project is an interactive process which overlays maps of project on those of present eco-environment. And soil, land use, wild life, vegetation, and erosion are the most important contains in eco-environment impact assessment for hydropower project.(3) Eco-environment management system for hydropower project includes setting up organization, drawing up regulations, clarifying responsibility, specializing measures. And according to different stages of measures for eco-environment protection, eco-environment management system for hydropower project should be divided to three different stages which contain design, construction and operation.(4) Taking Wulong mountain pumped storage power project as example, and basing on interpretation of remote sensing images, examination of routes, investigation of typical area and consultation of experts, this paper first finds out characteristics of terrestrial eco-environment in researching area, and then analyzes the impact causing by construction of hydropower qualitatively and quantitatively. So in order to harmonize construction and eco-environment protection, this paper also proposes countermeasures for problems and establishes eco-management system which can ensure the carrying out countermeasures and make countermeasures work more effectively in different stages of hydropower project. |
