The Evolution Analysis of Coordination Development between Environment and Economy in Xi'an City

运用区域经济学与城市生态环境学的理论,以西安市为例,选取表征环境、经济系统效益的指标建立协调发展的评判指标体系,应用主成分分析方法借助软件SPSS13.0,通过主成分载荷进行指标权重赋值,并根据离差分析原理建立协调发展度模型.结果显示,1998-2005年西安市环境与经济协调发展类型呈现由勉强协调环境滞后型到初级协调环境滞后型到中级协调环境经济同步型的演化轨迹,据此探讨了西安市经济与环境持续协调发展的机制.
