依据耕地变化特征与指标变化周期，从化学因子、物理因子和管理因子三个方面选取14个指标构建耕地质量动态监测指标体系，运用模糊灰色物元与克里格插值方法对公安县耕地等别更新进行了实证研究。结果表明：①公安县耕地整体质量略有下降，主要集中在东部县城及湖泊附近，土地整治与高产农田区耕地质量局部提升；②模糊灰色物元分析结合克里格插值能较好的平衡耕地质量动态更新的时效性、准确性与经济性之间的矛盾。

According to the characteristics of changes of cultivated land and the cycle of index change, author picks up 14 indexes considering the chemical factor, physical factor and management factor, using these indexes to construct the farmland quality dynamic monitoring indicator system. Then, the author use fuzzy grey matter-element method and Kriging interpolation to make an empirical study on the cultivated land grade update in Gongan county. Research conclusions: ①The overall quality of cultivated land in Gongan County is in slight decline whic...
