云南省水资源承载力与可持续利用研究

云南省水资源承载力研究中,采用了主成分分析方法,建立了反应云南省水资源承载力指标体系,在现有的资料基础上,选取12个指标进行主成分分析,从中提取3个主成分进行研究。从评价结果看出,云南省水资源承载力得分在2009年以后总体呈现下降趋势,2011年达到最低值,为-1.219 9,导致了水资源可持续利用受到影响,水资源承载力评价结果对可持续利用对策具有理论参考。

The Study on Carrying Capacity and Sustainable Utilization of Water Resource in Yunnan Province

Study on water resources carrying capacity in Yunnan Province, using the method of principal component analysis, set up the index system of water resources carrying capacity of Yunnan Province, on the basis of existing data, 12 indexes were selected by princi- pal component analysis, 3 principal components were extracted from the research. Seen from the evaluation results, water resources carrying capacity in Yunnan province in 2009 after the overall score showed a downward trend, in 2011 to the lowest value, - 1. 2199, led to the sustainable utilization of water resources is affected, the evaluation results of sustainable utilization countermeasures with the theoretical reference for carrying capacity of water resources.
