中文摘要：

以地学信息图谱理论为指导,结合福建省脆弱生态环境的现状和存在的问题,建立脆弱生态环境综合信息图谱谱系的指标体系,对福建省各县市的生态环境脆弱性进行评价,在全省各县市脆弱等级划分的基础上,通过聚类分析法,划分福建省脆弱生态环境的结构类型并进行规律和模式的挖掘.研究结果表明：（1）运用聚类分析对福建省脆弱生态环境结构类型进行划分是可行的;（2）福建省生态环境脆弱性较低,生态环境较优越;（3）采用图谱分析的方法能直观有效地把握脆弱生态环境的时空规律.

英文摘要：

Taking geological information map theory as the guide,this paper focuseson Fujian＇s fragile ecological environment situation and existing problems,and the way for reasonable utilization and protection of ecological environment,establishing an index system of fragile comprehensive information maps. The paper analyzes the ecological environment of the cities and counties in Fujian province. Based on the fragile assessment of various counties,through the hierarchy clustering analysis,it divides vulnerable ecological environment structure types of Fujian and excavates the rule and mode. The research results show that：（1） It is feasible to use clustering analysis to divide Fujian＇s vulnerable ecological environment structure type.（2） The ecological environmental vulnerability is low but the ecological environment is superior in Fujian.（3） Using the analysis method of visual maps can effectively grasp space-time rule of fragile ecological environment.
