Han River%water resources%carrying capacity%global principal component analysis
以湖北汉江生态经济带为研究区域,运用全局主成分分析法对该区域内10个城市近10年(2004-2013)来水资源承载力进行定量评价研究. 结果表明,湖北汉江生态经济带水资源承载力的主要影响因素为社会经济发展水平和自然水资源配比状况,并且呈现出明显的时空差异:空间上,社会经济发达地区水资源承载力强;时间上,水资源承载力呈现波动增强的趋势.
以湖北漢江生態經濟帶為研究區域,運用全跼主成分分析法對該區域內10箇城市近10年(2004-2013)來水資源承載力進行定量評價研究. 結果錶明,湖北漢江生態經濟帶水資源承載力的主要影響因素為社會經濟髮展水平和自然水資源配比狀況,併且呈現齣明顯的時空差異:空間上,社會經濟髮達地區水資源承載力彊;時間上,水資源承載力呈現波動增彊的趨勢.

The global principal component analysis (PCA) was used to quantitatively evaluate and study the carrying capacity of water resources in the ecological economic zone of Han River as the research area, including 10 cities during the near decade(2004-2013).The results indicated that the social economic development level and the water resource distribution were two main influence factors of the carrying capacity of water resources, which had obvious spatial and temporal disparities.The developed regions had strong carrying capacity of water resources in space and the carrying capacity of water resources showed a trend of fluctuations increased in time.
