摘　　要：根据福建省城市化和生态环境的特征,分别从人口城市化、经济城市化、社会城市化、空间城市化和生态环境水平、生态环境压力、生态环境保护共7个方面进行福建省生态环境与城市化耦合指标体系的构建。利用层次分析法确定指标权重,建立耦合度和耦合协调度模型,对福建省生态环境与城市化耦合关系进行定量分析,以地学信息图谱的方法进行图谱分析。研究结果表明:(1)福建省市辖区的耦合度优良,而下属的县区情况比较差,区域间的不平衡发展明显;(2)福建省的城市化和生态环境交互耦合的时序基本处于颉颃时期,但耦合度明显存在着地域差异;(3)福建省生态环境与城市化耦合关系比较好,协调度比较高,以中强度中协调的地区居多,低强度低协调的地区比较少,生态环境和城市化的整体协同效应比较好。According to the features of urbanization and the ecological environment in Fujian province,the coupling indicator system of ecological environment and urbanization was constructed based on seven aspects on population urbanization,economic and social urbanization,space urbanization and ecological environment level,ecological environmental stress,and the ecological environment protection.Using the AHP,the coupling coefficient and coupling coordination models were established to quantificationally analyze the coupling relationship of ecological environment and urbanization in Fujian province,and the method of geological information map was used to analyze maps.The research results are showed as follows：（1） The coupling of Fujian districts were good and counties situation of subordinates were poor,regional imbalance development was obvious;（2） The coupling interaction sequence of Fujian province＇s urbanization and the ecological environment was in equally matched period,but the coupling obviously existed regional differences;（3） The coupling relationship of ecological environment and urbanization in Fujian province was good,and the coordination degree was high,the areas of middle intensity and middle coordination were in the majority and the areas of low intensity and low coordination were less,the ecological environment and urbanization overall coordination effect was better.
