水电工程环境影响评价中生态评价方法研究

Research on ecological evaluation method in environment impact evaluation of hydropower project

结合构皮滩水电站和皂市水利枢纽等水利水电工程生态环境影响中生态评价方法和生态制图方法的实践经验进行了总结,其中生态评价方法主要是介绍了采用景观生态学的方法进行生态评价所需的各项生态分析数据的获取方法,生态制图方法分别介绍了利用收集基础图件和GIS技术进行生态制图的两种方法。通过构皮滩和皂市水利枢纽环境生态制图所取得的相关成果完全能满足现行《环境影响评价技术导则—非污染生态环境影响》所要求的基础图件和专业图件的要求,取得了令人满意的分析与评价效果。

This paper summarizes the practical experience of ecological evaluation method and ecological mapping method through the ecological environment evaluation of hydropower projects of Goupitan and Zaoshi etc. For the ecological environment evaluation method, the procuring method of various analysis data to be needed for ecological environment evaluation through landscape ecology is mainly introduced and for the ecologic mapping, 2 methods of basic picture collection and GIS technology are respectively introduced. The procured achievements through the ecologic environment mapping of Goupitan and Zaoshi hydropower projects can satisfactorily meet the demands of basic and professional pictures in 《Technology Guidelines of Environment Evaluation -Non-Pollution Ecologic Environment》 and satisfactory analysis and evaluation effects are obtained.
