摘　　要：利用能值分析方法对福建省67个县市农业生态经济系统的资源禀赋条件、投入产出状况和环境负荷进行了系统分析,构建了反映农业生态经济系统综合水平的能值指标体系,运用因子分析法对其进行综合评价和排序分析,结果显示福建农业经济生态系统存在明显的县际差异,并根据Q型聚类分析方法将结果划分为强协调发展型、较强协调发展型、较弱协调发展型、不协调发展型和极不协调发展型5种空间模式。探讨各模式的发展特征与生态经济协调状况,为促进农业生态区划与目标管理提供较为科学的依据。This article systematically evaluates the resource status, input-output condition and environmental loading ratio of the agro-ecosystem in Fujian province based on emergy analysis. The comprehensive assessment emergy index system of agro-ecosystem was established, then basic characters and regional differences of agro-ecosystem sustainable ability in Fujian were comprehensively examined by using the technique of factor analysis and software SPSS 13.0. The results show that there is a clear difference of agro-eeosystem synthesis level in different counties, and five spatial types were classified according to the results by Q-type clustering analysis. The development characteristic and harmony degree of eco-economic system were discussed in each type area, the purpose is to provide scientific base for improvement of ecological planning and object management for agriculture development.
