摘要
[目的]对四川省北川县环境地质承载力进行评价,为区域发展规划及建设提供科学依据。[方法]结合涪江流域的环境地质特点及社会发展情况,构建基于地质环境、生态环境和社会环境3个方面共10个评价指标层的环境地质承载力评价体系,采取层次分析法与专家打分法判定各评价指标权重,并通过GIS栅格功能对现状下北川县环境地质承载力进行综合评价。[结果]获得北川县的现状环境地质承载力分区图,划分出承载力状态高、较高、较低和低4种区域。[结论]北川县现状环境承载力分布与人类工程建设相关,总体上呈现人类聚集程度高而承载力状态低的趋势。
[Objective]The environmental geological carrying capacity of Beichuan County,Sichuan Province is evaluated to provide scientific basis for development planning and construction.[Methods]Combined with the environmental geological characteristics and social development of Fujiang River basin.the environmental geological bearing capacity evaluation system based on geological environment,ecological environment and social environment was constructed.The weight of each evaluation index was determined by analytic hierarchy process and expert scoring method.The environmental geological bearing capacity of Beichuan County is evaluated comprehensively through GIS grid function.[Results]The present situation of Beichuan County is obtained.And four regions of high,higher,lower and low bearing capacity are divided.[Conclusion]The distribution of current environmental carrying capacity in Beichuan County is related to human engineering construction.In general,there is a trend of high degree of human aggregation and low bearing capacity.
