基于DPSIR和主成分分析的阜康市水资源承载力评价
Evaluation of water resources carrying capacity of Fukang based on DPSIR and principal component analysis
摘要
Abstract
Fukang city in Xinjiang province is faced with increasing scarcity of water resources and worsening ecology. Basedon DPSIR, we conducted factor analysis of water resources carrying capacit y ( WRRC) and built a basic indicator system. Principal component analysis was used to select the main indicators of WRRC and entropy weight analysis was used to determine their weights. A comprehensive evaluation model was built to calculate and evaluate the WRRC of Fukang. The results showed t hat the selected 4 main indicators can well represent the basic indicator system w ith an accumulative cont ribution rate of 92. 016% . The WRRC of Fukang fluctuated between 0. 498-0. 531 during 2006-2014. The rate of decline was slow and the fluctuation range decreased w ith time. Generally, the ut ilization has reached saturation. The increased use of agricultural water resulting from social and econom ic development was a main indicator of the decline in WRRC. But the trend of decline was strongly re-lieved by the expanding groundwater exploit ation and water resources management practices in Fukang.关键词
