摘　　要：基于地理信息系统和农用地分等理论,运用ArcGIS空间分析功能设计耕地入选基本农田定量评价体系,划定基本农田.秀山县新一轮基本农田划定面积46 799.18hm2,通过对农用地分等数据的统计分析,以及耕地图斑层内及耕地图斑与交通干线的分析、居民点层间的叠加分析和对栅格图层的叠加分析,得到入选基本农田保护区耕地的综合等级为3.30-5.96.结果表明：基本农田划定同时满足数量和质量两方面要求,注重优化空间布局;运用ArcGIS空间分析结合农用地分等资料划定基本农田,可在达到数量要求的前提下使新一轮基本农田质量提升,布局优化.The purpose of this paper is to design a quantitative evaluation system for farmland to be designated as basic farmland and to explore a new way to demarcate basic farmland with a new perspective based on the theory of Geographic Information System and farmland grading. The research adopts the method of ArcGIS spatial analysis. In the new round of basic farmland planning, Xiushan County takes responsibility for designating 46 799.18 hectares as basic farmland, whose comprehensive grade ranges from 3.30 to 5.96. It is concluded that basic farmland planning should meet the requirements of both quantity and quality and pay more attention to the optimization of spatial layout, and that the combinative use of ArcGIS spatial analysis and farmland grading data not only meets the quantity requirement of basic farmland but also enhances its quality and optimizes its spatial distribution.
