摘要： 根据农业生态环境评价指标筛选的原则，建立由13个因子组成的福建省农业生态环境质量评价指标体系，分省、地市、县分析各区各因子时空变化。结果表明：13个农业生态环境因子中除了旱涝保收面积占耕地面积百分率、灾害面积率为东部沿海好于西北部外，大多数因子西北部好于东部沿海。福建省耕地面积占土地面积百分率、草地面积占土地面积百分率、灾害面积率、人均耕地面积、单位耕地面积农药使用量、单位耕地面积化肥使用量呈逐年代变差的趋势。提出了农业生态环境保护的对策。

Abstract: Index system for the agricultural eco-environmental quality in Fujian was established by 13 indexes closely related to the quality. The spatial variation figures of agricultural eco-environmental factors in every decades based on GIS were made. The factors values on the province ,districts and counties were analysed. The results showed that the majority factors in Fujian was changed into bad with decade and form northwest to southeast of Fujian. Ratio of cultivated area to total acreage, ratio of grassland area to total acreage, ratio of disaster area, farmland areas per person , pesticide input and fertilizer input was changed into bad with decade . Key words: agricultural eco-environment; assessment factors; temporal and spatial distribution ; Fujian Province
