摘要
采用修正后的相对资源承载力模型从时间和空间对玉树州资源承载力进行评价,结果表明:1999—2008年间,玉树州相对资源承载力处于富余状态,但富余量在逐渐减小;土地资源承载力远大于经济资源承载力,其中牧草地资源和林地资源对综合资源承载力贡献最大;资源承载力空间分布特征明显,主要表现为东西部和南北部的资源承载力分布差异。
By using the improved model of relative carrying capacity of resources, this paper evaluates the spatial-temporal carrying capacity of resources in Yushu area The result shows that the relative carrying capacity of resources was in a surplus state from 1999 to 2008, but the surplus was decreasing. The carrying capacity of land resources is much higher than that of economic resources, and the resources of grassland and woodland have made the greatest contribution to the carrying capacity of synthetic resources. In addition, the carrying capacity of resources in Yushu area is characterized by an obvious spatial distribution, with differences of the carrying capacity between the west-eastern areas and the north-southern areas.
