区域相对资源承载力时空动态研究——以陕西省为例

Analysis on the Relative Carrying Capacity of Region's Resources ——A Case Study of Shaanxi Province

本文运用相对资源承载力的研究思路和计算方法 ,并通过对原方法改进创新 ,以全国为参照区 ,分别计算分析了 :1陕西省二十年来的相对资源承载力及其演化过程。 2陕西省与中国西部地区、东部地区相对资源超载力的差异。 3陕西省三大地理单元——陕北地区、关中地区、陕南地区相对资源承载力及其内部区域差异。结果表明 :1陕西省自然资源承载力对综合资源承载力的贡献远远大于经济资源承载力的贡献 ,综合资源承载力的增长整体上一直低于全省人口的增长。 2与东部地区相比 ,陕西省综合资源承载压力远大于东部地区 ,与西部地区相比 ,其综合资源承载力超载程度也高于西部整体水平。3全省不同地区的资源承载力差异十分显著。

This research applied and reformed the method of the relative carrying capacity of resources, and calculated the carrying capacity of land resources and economic resources, and synthetic carrying capacity of resources of Shaanxi province from 1982 to 2002, analyzed the difference of the carrying capacity of between Shaanxi province and the eastern zones as well as the western zones compared with the whole country. It also calculated the carrying capacity of different regions in Shaanxi province. Thus conclusions were drawn: ①the contribution of land resources to the synthetic carrying capacity was much greater than the economic resources; ②the pressure from the carrying capacity of Shaanxi province was much greater than the eastern zone and was a little greater than the western zones; ③the difference among the carrying capacity of the different regions in Shaanxi province was obvious.
