摘　　要：本研究基于GIS软件的空间分析工具,通过选取适宜松桃县的耕地质量等别评定基本参数、评价指标体系及权重,采用“因素法”对2019-2020年度新增、减少类耕地及质量建设耕地等别变化范围进行评定。结果表明,2019-2020年,松桃县减少耕地面积871.02 hm^(2),新增耕地159.91 hm^(2),新增耕地等别集中在9~11,质量建设耕地226.26 hm^(2);与“三调”统一时点耕地质量等别成果对比,提升0.01等别。基于本次耕地质量等别成果动态更新,以期为地区实现耕地资源信息的社会化服务及自然资源数量质量并重管理提供参考。This study is based on the spatial analysis tools of GIS software,by selecting the basic parameters,evaluation index system and weight for the quality evaluation of cultivated land suitable for Songtao County,the“factor method”was used to evaluate the change range of the newly added,reduced cultivated land and quality construction cultivated land in 2019-2020.The results show that,Songtao County reduced the area of arable land by 871.02 hm^(2),increased arable land by 159.91 hm^(2),the newly increased arable land was concentrated in the 9-11 grade,and the quality construction arable land was 226.26 hm^(2)in 2019-2020.Compared with the results of the three-adjustment unified time point of the cultivated land quality grade,the grade is increased by 0.01.Based on the dynamic update of the results of the quality of cultivated land this time,it is expected to provide a reference for the region to realize the socialized service of cultivated land resource information and the management of both quantity and quality of natural resources.
