文章摘要：根据道路选线工程成本思路提出了道路选线的“栖息地成本”的概念,以此量化道路对所穿越野生动物栖息地造成的影响。以椅子垭口大熊猫栖息地内的道路选线为例,基于保护生物学的栖息地评价结果计算出栖息地成本值;用地形因素代表道路工程成本,将栖息地成本与工程成本以不同权重组合代表环境因素在道路选线中的重要性、生成道路选线的综合成本,通过Arcgis的distance模块计算出9条穿越椅子垭口综合成本最小的路径,提出了道路优化的方案,供道路建设选线参考。通过野生动物栖息地对基于环境因素的道路选线方法进行了探索,使道路建设的环境保护需求在选线阶段就得到充分的考虑,对提高我国道路选线水平、道路建设和野生动物保护成效具有现实意义。

Abstr：Our research, based on the theory and methodology of route selection on project cost, proposed the ＂habitat cost＂ concept that is used to quautify the impacts of road construction to wildlife habitat. Taking the route selection within giant panda habitat as a case in Yiziyakou, we got the value of habitat cost based on the results of habitat assessment by conservation biology. Topography was used to represent the construction cost of road, we got 9 routes passing Yiziyakou for future reference of the road construction, with the least total cost at various cost ratios of construction to habitat showing the degree of environment consideration in route selection by the distance model of Arcgis. Our study sought the route selection method based on environment protection consideration through wildlife habitat, this ensures the requirement of environment can he considered during route design and selection process. It may also be helpful to improve the level of route selection, further the results of road construction and wildlife conservation in China.
