基于AHP的内蒙古S203公路景观评价指标体系

摘要

针对我国草原公路景观环境影响评价多为定性分析、评价内容庞杂无序的现状,通过对我国大量草原公路景观环境的研究、调查及分析,从小尺度方向上分析景观空间格局,提出选取反映出景观破碎度及景观多样化指数、公众关注度等指标体系对草原公路景观进行定量评价;并借助AHP层次分析法,为内蒙古自治区S203路阿拉坦额莫勒至阿木古郎段草原公路景观构建评价指标体系.通过计算分析,并经过工程实施验证后得出本条草原公路景观环境协调性评价结果为良好.此课题的研究成果大部分已成功应用于草原公路建设中,为该条公路的景观改善发挥了重要作用.%Grassland highway landscape environmental impact assessment in China are mostly qualitative analysis, disorderly e-valuation content and confused by a lot of grassland in our country.We studied the highway landscape environment by high-way aesthetics and visual quality in grassland.From small scale landscape spatial pattern of the analysis, we put forward selection reflecting the landscape diversity index, landscape fragmentation and public attention index system for quantitative evaluation on the grassland highway landscape environment.By AHP analytic hierarchy process, we built the evaluation in-dex system of the grassland highway landscape of the grassland road of Alatan in Inner Mongolia Autonomous region 203rd. Through the calculation and analysis, we obtained the evaluation results of the landscape coordination of the prairie road. The research results of this project was successfully applied in the practice of grassland highway construction with an impor-tant role in the landscape construction of the highway.
