摘  要：
随着我国人口的不断增长,土地的承载能力和粮食安全问题越来越受到广泛的关注。本文从人粮关系角度出发,基于可持续发展基本理论,运用土地资源承载力(LCC)模型,以我国农业和人口大省河北省为例,对河北省土地资源承载能力进行了计算,并以土地资源承载指数(LCCI)为指标,以县级行政地区为单元划分了土地资源的人口承载力等级。结果表明,河北省68.71%的县域为粮食盈余区,17.01%的县域为人粮平衡区,其余14.28%的县域为粮食超载区。在此基础上对河北省具有代表性的县域单元进行了讨论,并提出了提高土地资源人口承载力的对策。

摘  要：
With the increase of population,land carrying capacity and food safety have attracted great attention worldwide.From the point of man-grain relationship,on the basis of the theory of sustainable development,by using the land carrying capacity(LCC) model,this paper selected the Hebei Province as the example that has the with the features of large population and developed agriculture.This paper first calculated the carrying capacity of land resources in Hebei Province,and then at the county level,using the land carrying capacity index(LCCI) as indicators,and graded of the land carrying capacity by taking the county level administration region as the unit.The result shows that,68.71% of the counties in the Hebei Province were surplus in grains and 17.01% of the counties were balance between population and grains,while the other 14.28% of the counties were overloaded.Based on the result,this paper discussed the carrying capacities of the representative counties in Hebei Province and proposed some solutions on improving the land resources carrying capacity.
