摘　　要：高速公路建设在延伸区域可达性、支持沿线区域经济带发展以及促进整个社会的经济发展中发挥着不可替代的作用。但部分公路建设给沿线生态环境带来严重影响,如何科学、合理地对道路进行生态选线已成为行业中重点考虑的问题。文中研究结合遥感数据、野外实地调查数据及统计年鉴数据选取了8种一级评价指标和26种二级评价指标,运用层次分析法进行权重赋值,应用GIS空间分析的栅格计算器(Raster Calculation)进行生态选线研究,定量评估了依托工程所在区域的公路建设生态适宜性,对比分析了不同路线方案的生态适宜性和综合环境影响。Expressway plays an irreplaceable role in extending regional accessibility,supporting the development of regional economy and promoting the economic development of the whole society.However,highway construction may also cause significant impact on the ecological environment along the road.How to rationably select a eco-friendly route has become the key problem.Based on remote sensing data,statistical data and field investigation,in this paper,AHP and Raster Calculation are employed to establish an indices system of 8 primary indicators and 26 secondary indicators,and the analytic hierarchy process is used to assign weights.The GIS spatial analysis Raster Calculation is used to carry out ecological route selection study,the ecological suitability of highway construction in the area where the project is located is quantitatively evaluated,and the ecological suitability and comprehensive environmental impact of different route plans are compared and analyzed.
