摘要
本文在分析甘肃省耕地资源现状承载力的基础上,对未来不同时期耕地资源承载力进行了预测。结果表明:如果按人均粮食400kg计算,甘肃省2010年、2015年和2020年分别超载352.88万人、213.91万人、10.05万人;如果按人均粮食450kg计算,甘肃省2010年、2015年和2020年分别超载623.24万人、514.97万人、345.31万人。不同类型生态区之间存在较大的差别。
The populationsupporting capacity of cultivated land in Gansu in 2003 was analyzed,and the predictionsof the populationsupporting capacity of cultivated land of Gansu in the different periods in thefuture were taken.It was showed: inlight of 400kg of the average food possession,theoverload population was 3,528,800,2,139,100and 100,500 in 2010,2015and 2020 respectively.In light of the450kg of the average food possession,the overload population was 6,232,400,5,149,700and 3,453,100 respectively.It were distinc...
