摘要
水资源系统与社会经济生态系统的协调性已越来越引起关注。首先利用主成分分析法,分别求出水资源系统与社会经济生态系统的综合评价指数,然后采用距离协调度模型得到两个系统间的协调度值,对两个系统的协调性进行了定量分析。以山东省为例,计算了2001-2012年两系统的协调度值。结果表明:两系统综合评价指数总体趋势上升;两系统发展虽然不同步,但协调性良好。
Under the background of promoting optimal allocation of water resources and constructing resources-saving type society,the harmony of water resources system and the social economic ecological system has been widely noted.This paper uses principal component analysis to get the comprehensive evaluation index of water resources system and the social economic ecological system and then distance coordination degree is used to get the coordination degree between the two systems,and the research is used in Shandong Province to calculate the coordination degree from 2001 to 2012.The results show that the comprehensive evaluation index of the two systems is rising.The development of the two systems is not synchronized but harmonious.
