公路建设对所处地域自然生态环境势必产生一定破坏, 建立环境影响评价指标体系并应用于公路-环境交互式设计十分有必要.构建水土流失、生态系统及其服务功能、生态环境质量综合指标评价体系, 结合实际工程对山区公路桥隧比、填挖高度、路基宽度、生态补偿等设计指标的生态环境影响进行定量评价, 为生态保护区域其他公路工程设计提供有益参考.%The highway construction is bound to destroy the natural ecological environment in the region. It is very necessary to establish an environmental impact assessment index system and apply it to highway-environment interactive design. The aggregative indicator evaluation system of soil erosion, ecosystem and its service function, and ecological environment quality is built. Combined with the practical projects, this paper quantitatively evaluates the ecological environment impact of design indexes such as bridge-tunnel ratio, filling height, roadbed width and ecological compensation of highway in mountainous areas, which provides the useful reference for the design of the other highway projects in ecological protection area.
