福建省农业生态环境质量指数的时空动态变化

根据农业生态环境质量评价指标筛选原则,结合福建省农业生产特点,邀请省内外农业生态环境专家对19个候选因子进行排队打分,建立了由13个因子组成的福建省农业生态环境质量指数评价指标体系和农业生态环境质量总指数计算公式。利用GIS技术制作了不同时段（20世纪80年代、90年代、2001-2005年）福建省分县级农业生态环境质量指数分布图,计算各年代省级、地市级、县级农业生态环境质量指数。结果表明：福建省的农业生态环境质量随年代逐渐变差,各地农业生态环境质量指数为1级（农业生态环境质量好）的县数随年代减小,5级（农业生态环境质量差）的县数随年代增加;从空间分布看,东南沿海农业生态环境质量差或较差,西北地区较好。

Temporal and Spatial Change of Agricultural Eco-environmental Quality Index in Fujian Province

According to the collecting principle of agricultural eco-environment quality assessment index,combining agricultural production practice in Fujian province,the assessment index system of agricultural eco-environment quality composed 13 factors and the general index formula of agricultural eco-environment quality were established.The index chat of agricultural eco-environmental quality in decades was made based on GIS,and the indices in different regions were calculated.The results showed that the agricultural eco-environmental quality became worse in recent decades in Fujian province.The area with grade 1 was shrunk,and the area with grade 5 was extended.From spatial aspect,Northwest Fujian was better than Southeast.
