Abstract:

This paper, based on historical land area and population in China, calculates the maximum land area for one rural labor under “labor matching with employment” at traditional plowing modes, and estimates the minimum labors for farmland to load in 2008, 2020 and 2030 at multicropping index 1, 1.26 and multi-cropping index 1.26 & minimum operation, the surplus labor needs to migrate to cities. This paper, according to urban planning standards, works out the total urban construction land area and land area to be occupied. The rural residence left by farmers who migrate to cities, after rehabilitation, can be used for added land area, which is balanced with occupied construction land area. The both are used to calculate the preserved farmland area in China.

Key words: labor matching employment, farmland, urban, rural residence

摘要：

本文根据我国历史上耕地面积和人口数量，得到传统耕作方式下农业“力业相称”时每个农村劳动力的最大耕种面积。以此数据为基点，推算了在复种指数为1、复种指数为1.26、复种指数1.26和最小规模化经营3种情况下，2008年、2020年、2030年耕地能够承载的最小劳动力，需要转入城市的人口数量。按照城镇规划的标准，计算出了我国城镇建设占用的总面积，城镇还需占用的土地面积。转入城镇的农村人口留下的农村居民点经过复垦整理增加的耕地面积和建设用地占用耕地面积相挂钩，最后得出我国耕地保有量的面积。
