摘　　要：依据大量相关研究、文献资料和洞庭湖区的实地考察,分析了导致洞庭湖湿地生态环境历史演变的各种影响因素。就公路建设影响洞庭湖湿地生态环境的主要效应进行了研究。认为公路城镇化效应以及公路水利效应是影响的主要方面。建立了相关的评价指标体系。指标体系由公路等级指标、公路城镇化效应指标以及公路水利效应指标构成。为基于3S技术监测评价公路建设影响洞庭湖湿地生态环境奠定了基础。On the basis of a large number of research documents and on-the-spot investigations of Dongting Lake, various factors are analyzed which caused historical evolution of ecological environment of Dongting Lake ecotope in this paper. Main actions of influence of highways on ecological environment of Dongting Lake ecotope are studied. This is put forward that urbanism action and water conservancy action of highways are the main actions of influence of highway on Dongting Lake ecotope. The assessment index system of influence of highway on Dongting Lake ecotope is set up. The index system consists of classification of highway, urbanism action of highways and water conservancy action of highways. The index system is the base of assessment about influence of highways on Dongting Lake ecotope with 3S Techniques.
