摘　　要：从耕地的自身条件、地形、区位及社会经济发展状况出发,建立耕地入选基本农田的指标体系;再运用GIS中栅格数据的空间分析方法,对每个象元的影响因子进行综合分析、评价,从而得到每个象元的得分情况;通过耕地适宜性评价分析,同时考虑未来建设占用耕地的情况,最终得出龙潭镇规划期末基本农田布局图.The distribution of basic farmland is one of the important contents in the new round of the general land use planning.It can be described as the process in which some cultivated land defined in the general plans for land utilization is given priority to be demarcated as basic farmland based on certain indexes.This paper is aimed at formulating such an index system of basic farmland based on the specific conditions of the cultivated land,and its terrain,location and social and economic development.With the help of spatial analysis of grid data in GIS,the influence factors of each pix are comprehensively analyzed and evaluated and the scores of each pix are obtained.Through the suitability analysis of cultivated land in combination with a consideration of possible future transformation of cultivated land into construction land,a basic farmland layout diagram of LongTan town at the end of the planning period is drawn,which may provide services for the next overall land planning.
