基于主成分分析的湖北省水资源承载力研究

Study on the Carrying Capacity of Water Resource in Hubei Province Based on Component Analysis

以湖北省为例,选取17个指标进行主成分分析,从中提取出3个主成分对湖北省水资源承载力进行研究。结果表明,2000～2008年,湖北省水资源承载力呈现逐年增加的趋势,但在2001年出现了小的波动,就其原因进行了分析,得出经济发展和水资源利用情况是影响水资源承载力的主要因素,总体上湖北省水资源承载力向好的方向发展。

Taking Hubei province as an example,17 indexes were selected to do component analysis in this article.Three components were extracted from 17 indexes to study carrying capacity of water resource in Hubei province.The statistics from 2000 to 2008 reflected that the carrying capacity of water resource in Hubei province increased year by year apart from 2001.Economic development and water use were the main factors affecting carrying capacity of water resources.As a whole,the carrying capacity of water resource in Hubei province was on the positive tendency.
