基于相对资源承载力的青海省区域可持续发展研究

Relative Carrying Capacity of Resources and Problems in Sustainable Development of Qinghai Province

本文采用相对资源承载力的研究思路和分析方法,计算和分析了1978-2008年30年间,青海省相对土地资源承载力、相对经济资源承载力和相对综合资源承载力的状态及其演化过程,研究结果表明:①青海相对资源承载力不稳定,1979-2008年期间,除1999年和2000年以外,其他各年份青海实际人口超过综合承载力,处于超载状态;②在青海综合承载力中土地资源的承载力大于经济资源的承载力,土地是青海人口的主要承载资源;③青海相对土地资源和经济资源之间的不协调将是青海省今后可持续发展战略中的重要问题。

There were numerals defects in the past research on the carrying capacity of resources,so this paper adopts the calculating methods of relative capacity of resources.The relative carrying capacity of land resources,relative carrying capacity of economic resources and synthetic carrying capacity of resources of Qinghai province have been calculated from 1978 to 2008.Thus conclusions were drawn ： ①the relative carrying capacity is varying in Qinghai province;The synthetic carrying capacity exceeded the real population in Qinghai Province from 1978 to 2008-except1999 and 2000,which was in a relatively enough situation.②the synthetic capacity of land resources in Qinghai province are greater than that of economic resources,so the land resources are the principal resources to support population;③the incoordination between the relative carrying capacity of land resources and that of economic resources is a significant problem to be solved in the strategy of sustainable development in Qinghai province.
