以岷江上游流域TM遥感数据和地形数据为主要数据源,结合其他统计相关资料,尝试运用层次分析法( an-alytic hierarchy process,AHP)对复杂因素构成的脆弱性特征进行层次分解和重新构造,建立多目标要素的综合评价指标体系和模型。选取植被指数变化率、人口密度、地形起伏度、坡度及土壤类型5个要素作为评价指标因子,通过AHP确定各评价指标的权重,在ArcGIS平台下将各指标图层进行叠加分析,得出岷江上游区域环境脆弱性评价图,再根据环境脆弱性指数阈值分级,将研究区环境脆弱度分为5级。结果表明：岷江上游环境脆弱性表现较为强烈,自然因素和人文因素是造成该环境脆弱性的本质原因,该方法为岷江上游流域环境脆弱性模式和生态环境综合评价提供了一种定量分析的思路。

With TM remote sensing data and topographic data as the main data sources, coupled with other statistical information obtained in the upper reaches of Minjiang River, the authors tried to apply the analytic hierarchy process ( AHP ) to reframing the vulnerability characteristics resulting from complicated factors and establishing the comprehensive evaluation index system and the model with multiple objective elements. Vegetation index change rate, population density, terrain relief, slope and soil type were five factors serving as evaluation index factors in the AHP to determine the weight of each evaluation index, and superimposition analysis of the indicators was made on the ArcGIS platform. The grade map of comprehensive evaluation on ecological environment in the reaches of the Minjiang River could be obtained, which was classified into five degrees in the environmental vulnerability. The results achieved by the authors indicate that environmental vulnerability of the upper reaches of the Minjiang River is extremely intense, caused mainly by natural factors and human factors. The results of his study provide the quantitative and qualitative scientific basis for the construction of the environmental vulnerability pattern and the comprehensive evaluation of ecological environment along the upper reaches of the Minjiang River basin.
