基于主成分分析的福建省水资源承载力时空变化研究

Study on the Temporal and Spatial Variation of Water Resources Carrying Capacity in Fujian Province Based on Principal Component Analysis

为揭示福建省水资源承载力时空变化特征,利用SPSS软件中的主成分分析功能模块,选取福建省2004～2017年和福建省各地市2017年的15个水资源承载力评价指标进行评价。结果表明:人口与社会经济发展水平、水资源禀赋条件、水资源利用程度是影响福建省水资源承载力的主要因素;在时间上,2004～2017年福建省水资源承载力总体上呈不断上升的趋势,人口与社会经济发展水平因素对其影响尤为突出;在空间上,福建省水资源承载力呈现泉州>福州>漳州>南平>三明>龙岩>厦门>莆田>宁德>平潭的空间分布特征,空间分布规律与各地区的水资源禀赋条件差异、水资源利用程度联系密切。

In order to reveal the spatial and temporal characteristics of water resources carrying capacity in Fujian Province, 15 water resources carrying capacity evaluation indicators in Fujian Province from 2004 to 2017 and in Fujian Provinces and cities in 2017 were selected and evaluated by using the principal component analysis function module of SPSS software. The results show that population and socio-economic development level, water resources endowment conditions and water resources utilization degree are the main factors affecting the water resources carrying capacity of Fujian Province. In terms of time, the water resources carrying capacity of Fujian Province from 2004 to 2017 is generally appears the increase trend, especially the population and socio-economic development level factors have the outstanding impact.In terms of space, the water resources carrying capacity of Fujian Province is particularly prominent. It presents the spatial distribution characteristics of Quanzhou Municipality> Fuzhou Municipality> Zhangzhou Municipality> Nanping Municipality> Sanming Municipality> Longyan Municipality> Xiamen Municipality> Putian Municipality> Ningde Municipaity> Pingtan Prefecture. The spatial distribution rule has the close relationship with the difference of water resources endowment conditions and the degree of water resources utilization in different regions.
