确定山西省人口耕地承载力,在考虑山西省耕地生产力水平的基础上,同时参照国家1988年提出的2000年小康标准.通过统计分析表明:我省人口耕地承载力现状:按温饱型生活标准,超载537.12万人,粮食缺口21.48亿公斤;按宽裕型生活标准,超载812万人,粮食缺口36.5亿公斤.预计本纪世末,人均粮食占有水平仅是略超温饱型不达宽裕型.
The purpose of this paper is to determine the bearing capacity of cultivated land to the population of Shanxi. By taking account of the land productivity of Shanxi and consulting the well-off standard in 2000 issued by nation 1988. We showed the status of the bearing capacity of cultioated land to population after statistic analyzing : In light of the lioing standard of full food, (the average food possesion is 400kg), the overload population is 5, 371, 200, the food lacking amount is 2, 148, 000, 000kg.
