文章摘要：根據(jù)道路選線工程成本思路提出了道路選線的“棲息地成本”的概念,以此量化道路對所穿越野生動物棲息地造成的影響。以椅子埡口大熊貓棲息地內(nèi)的道路選線為例,基于保護(hù)生物學(xué)的棲息地評價結(jié)果計算出棲息地成本值;用地形因素代表道路工程成本,將棲息地成本與工程成本以不同權(quán)重組合代表環(huán)境因素在道路選線中的重要性、生成道路選線的綜合成本,通過Arcgis的distance模塊計算出9條穿越椅子埡口綜合成本最小的路徑,提出了道路優(yōu)化的方案,供道路建設(shè)選線參考。通過野生動物棲息地對基于環(huán)境因素的道路選線方法進(jìn)行了探索,使道路建設(shè)的環(huán)境保護(hù)需求在選線階段就得到充分的考慮,對提高我國道路選線水平、道路建設(shè)和野生動物保護(hù)成效具有現(xiàn)實意義。

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.
