相对资源承载力模型改进及其应用

分析了当前国内研究区域可持续发展的相对资源承载力模型存在的一些不足,如静态分析时,模型没有考虑不同地区资源的利用效率和生活水平等的差异;动态分析时,选取的参照区包含了研究区作为其子集.通过引入修正因子、从参照区中分离出研究区等方法对原模型进行了相应的改进.以2005年我国28个省市和2000~2007年新疆的可持续发展研究为例,运用改进后的模型分别进行了静态和动态研究.结果表明:2005年在全国28个省市中,根据传统模型计算得到人口超载、富余的省市数分别有18,10个,而根据改进后模型计算得到人口严重超载、超载、富余和非常富余的省市数分别有13,6,4,5个;改进后模型计算得到2000~2007年新疆的综合承载力要大于传统模型计算得到的结果;改进后模型计算的结果比原模型的结果更加精准.

Model modification and application of the relative carrying capacity of resources

This paper pointed out several major deficiencies in the traditional model of relative carrying capacity of resources,such as efficiency of resources using and difference of living standards in different regions were not considered in the static analysis,the reference area which included the study area was selected as a subset in the dynamic analysis.And it did some corresponding improvements by means of introduce correction factors,isolate the study area from the reference areas and so on.Meanwhile,took the study of sustainable development of Chinese 28 provinces and cities in 2005 and Xinjiang from 2000 to 2007 as examples,used the modified model did static and dynamic analysis respectively.Among 28 provinces and cities during 2005,the number of provinces and cities which population stated overload,surplus was 18 and 10 respectively calculated by traditional model;while the number of provinces and cities which population stated serious overloading,overloading,surplus and very abundant was 13,6,4 and 5 respectively calculated by modified model.The results of integrated capacity of Xinjiang from 2000 to 2007 which calculated by modified model were greater than those did by traditional model.The results calculated by modified model were more precise than those did by traditional model.
