摘　　要：四川省地处长江上游,对其进行生态环境脆弱性评价与分析,有利于全省及下游地区社会经济发展及生态环境保护与建设。研究以生态敏感性-生态恢复力-生态压力度(SRP)模型为框架,从气象、地形、生态景观等方面选取14个评价指标,利用空间主成分分析综合评价对四川省生态环境脆弱性进行综合分析。结果表明:全省生态环境状况总体良好,大部分地区处于中度脆弱以下水平;生态脆弱度呈现由南向北逐渐增强的变化趋势。The ecological vulnerability assessment and analysis of Sichuan province, located in the upper reaches of the Yangtze river, will be conducive to the development of social economy and ecological environment protection and construction in the whole province and downstream areas. In this study, 14 evaluation indexes are selected from the aspects of meteorology, topography, ecological landscape and so on, based on the ecological sensitivity and ecological resilience （SRP） model as well as comprehensive evaluation of ecological vulnerability in Sichuan province by using spatial principal component analysis. The re-sults showed that： the ecological condi tion of the whole province was good. Most of the area was in the moderate level of vul-nerability, and the ecological vulnerability showed a trend change from south to north more serious.
