摘　　要：为及时掌握耕地质量变化状况,实现耕地数量与质量占补平衡,研究耕地质量监测具有重要的意义。综合了耕地质量的概念和吉安县实际情况,构建了耕地质量变化的评价指标体系和评估模型,以此为基础,对2010—2012年吉安县耕地生产力质量、耕地生态环境质量、耕地健康质量、耕地综合质量进行了监测。对比发现,吉安县耕地生产力质量总体呈下降趋势;吉安县耕地生态环境质量和健康质量在3年的短时间内都比较稳定;吉安县耕地综合质量呈上升的趋势,但上升的幅度不大。研究采用的综合指数法能较全面地体现吉安县耕地质量变化的综合特点,为如何开展耕地质量监测工作提供一定的技术参考。To achieve cropland replenishment balance of the quantity and quality of farmland,it is of great sense to mornitor the change of the farmland quality. An integrated index system for the evaluation of farmland quality was built synthesizing the concept of farmland quality and the actual condition in Ji＇an County. Using this method,the productivity quality,ecological environment quality,healthy quality,and overall quality of the farmland in Ji＇an County were mornitored from 2010 to 2011. The result indicated that the productivity quality showed a downward trend,the ecological environment quality and healthy quality were relatively stable; the overall quality showed a slight increasing trend. The method developed in this study can comprehensively reflect the characteristics of changes in farmland quality worth reference for monitoring cultivated land quality.
