摘要
为探究西宁市PREE系统的协调性,找到适合其城市发展的途径,选取西宁市1990—2007年的各项发展数据,建立评价指标体系。运用主成分分析法确定PREE系统的综合发展水平,最后引入模糊数学原理,对其PREE协调度进行定量分析。找到了影响其协调发展的主要因素,对西宁市未来的发展具有指导意义。
In order to study the coordination of Xining s PREE System and find a suitable method for the development of the city,the development data from 1990 to 2007 was selected to establish an evaluation index system.The principal component analysis is employed to determine the level of comprehensive development system.Finally the coordination of Xining s PREE system is quantitatively analyzed by introducing the principle of fuzzy mathematics.The main factors that impact the coordinated development are got,which possess guiding significance for the future development of Xining City.
