北京市基本农田保护区内耕地数量提升潜力研究

北京市已划定九大片基本农田保护区,对保护区内耕地数量提升潜力进行估算,可为北京市基本农田保护区内耕地保护和利用提供依据。基本农田保护区耕地数量的增加主要有三个来源:农用地中的非耕地通过农业结构调整和农田整理转化为耕地,建设用地中的农村居民点和废弃工矿通过整理和复垦转化为耕地,未利用开发转化为耕地。可调整地类可作为耕地增加的来源,规模约为4 789hm2,通过农田整治增加耕地规模约为3 300hm2;基本农田保护区内农村居民点腾退补充耕地约为7 500hm2,废弃工矿复垦退补充耕地的潜力约为272.24hm2;未利用地开发可补充耕地数量约为900hm2,主要分布在顺义东部片和平谷西南部片。

Study on Quantity Promotion Potential of Beijing Basic Farmland Protection Area

The purpose of this study is to estimate the development potential land in Beijing basic farmland conservation,and provide foundation for the land reclamation planning.The basic farmland protectorate farming quantity increasing mainly has three origins: the restructuring of the agricultural farmland construction,the reclamation of the countryside residential area,the abandons industry mining,and the development of the non-used farming land.The research results showed that the scale of the adjustable land class might increase approximately 4 789 hm2 farming land;through the farmland improvement,the scale approximately is 3 300 hm2;the returns of the countryside residential area vacate buildings was approximately 7 500 hm2 and the potential of the industry and mining could draw back farming land approximately 272.24 hm2.The development of unused land was possible to supplement 900 hm2 of farming land,which mainly distributed at the east part of Shunyi and the southwest part of Pinggu.
