利用地理信息空间数据处理技术，对土地利用现状数据、土地利用总体规划数据、永久基本农田保护数据、生态红线、土地复垦开发、坡度、森林资源普查、基础国情普查、农经权调查等数据进行融合、分析、提取逻辑运算，从现势的地理空间数据里获取耕地占补平衡后备资源数据后，叠加高分辨率影像进行人工解译，确定后备资源地块的空间位置，制作工作底图；同时，根据农经权调查结果，对后备资源进行筛选，提高了工作效率。此方法在云南某市进行了尝试，取得了较好的效果。
Using geographic information spatial data processing technology, we obtained the occupation and compensation balance resource data by merging land use status data, land use overall planning data, permanent basic farmland protection data, ecological red line, land reclamation development, slope, forest resource survey, basic national conditions survey, agricultural economic rights survey, and the working map is produced. At the same time, according to the results of the survey on agricultural economic rights, the selection of backup resources has improved the efficiency of work. This method was tried in a city in Yunnan and achieved good results.
