高速公路选线环境评价方法研究

以云南省大理～保山高速公路为依托，综合考虑地质环境、土地利用、水土保持和敏感目标等因素，以层次分析法建立了公路选线生态环境评价方法。在评价方法上，由定性评价实现了定量评价，可对公路沿线综合环境进行定量分析比较，以在区域中选择环境最小敏感走廊和对具体线路进行环境优化。

A Study on Environmental Assessment for Expressway Routing

The environmental assessment indexes of expressway routing are built to select the optimized environmental corridor and routes through Analytical Hierarchy Process Method on the basis of comprehensive considerations of environmental factors, such as geology, land use, soil erosion and sensitive objects, etc.. An index system is constructed to assess the ecology environment quantitatively, which offers the scientific assessment method to select optimal route on the basis of environment. Dali-Baoshan Highway in Yunnan Province is the case for the study.
