摘　　要：我国是一个多山的国家,生存空间的紧缺导致大量人口不得不生活于山区,同时为了克服山区相对较差的交通条件,人口又多聚集在公路沿线。山区公路沿线地质条件复杂,生态环境脆弱且社会经济发展相对落后,故而针对山区公路沿线开展地质、生态、社会环境的全方位调查与评价,对于山区社会经济可持续发展具有重要意义。以都(江堰)汶(川)公路沿线区域为研究范例:1)从地质、生态、社会发展三方面选取了共计18个指标,进行地质、生态、社会环境评价;2)基于GIS平台和一系列评价标准,对各评价指标进行量化计算,并以层次分析法确定各指标权重,得到地质、生态、社会环境三方面的评价分区结果;3)结合评价结果对研究区进行综合分区,并从耕地资源和建设用地两方面对研究区进行了人口承载容量分析。所得成果与研究区实际情况相符,对山区公路沿线区域发展规划有显著借鉴意义。Many people in China are living in the mountains because of the shortage of living space.To overcome the inconvenience of traffic,most of them choose to live along the paths.With the sophisticated geological setting,weak environment and the backward social economy there,launching the investigation and assessment along with the mountains＇ paths in the aspects of geology,zoology,society plays a positive role with the sustained economic growth in the mountains area.This subject takes area along the roads from Dujiangyan to Wenchuan in Sichuan of China as the research sample：1） Selecting 18 indexes based on geology,zoology and social economy to finish the corresponding assessments in the study area.2） Based on the GIS and a series of standards,this study needs to digitalize the selected indexes.With the assigned weights from AHP,then it can be calculated the specific results of each evaluation on the geology,zoology,and society.3） Combining with the evaluation results,the integrated partitions can be created in the research area.Choosing the agricultural land and architecture land from the partitions,the analysis of the population capacity can be finished.The final study result match the current situation of the research area.So it shows the good reference value on the mountains＇ road planning.
