县级耕地质量等别变化研究--以福建省福清市为例

摘要

Based on the cultivated land grading results in 2002,2009 and 201 3 in Fuqing City of Fujian Province,the temporal and spatial change characteristics of cultivated land gradation and their reasons were analyzed in this paper.According to the results,the overall level of cultivated land quality took on an increas-ing trend and the change range was not big from the point of time;and from the point of space,the change characteristics of all the index areas were basically identical,and cultivated land gradation showed an increas-ing trend compared with that in 2002,but in recent years the cultivated areas in most grades showed a slight decline.The research results could provide scientific basis and references for the protection and construction of cultivated land in this area.%以福建省福清市为研究区域，基于该区域2002年、2009年和2013年三轮耕地分等成果，分析其耕地等别时空变化特征及变化原因。研究结果表明，从时间上来看，福清市耕地质量总体水平呈不断上升趋势，但变化幅度不大；从空间上来看，各指标区耕地变化特征基本一致，相较于2002年，均呈现出上升趋势，但近年来大部分等别耕地面积呈现出略有下降的趋势。研究结果可为该区域耕地质量保护与建设提供依据和参考。
