摘要
目的衡量汉中市近10年城市化与生态环境发展的协调性。方法以汉中市1996—2009年统计年鉴数据为基础,建立城市化与生态环境交互作用下的两个子系统,运用主成分分析法确定两大子系统的综合发展水平,根据协同论的思想构建协调发展模型,进而评价城市化与生态环境发展的协调状况。结果 1996—2009年期间,城市化发展指数每年平均上升0.17点,生态环境指数每年平均上升0.15点,研究期末协调度指数为0.12。结论汉中市城市化与生态环境综合发展水平整体呈上升趋势,城市化的发展速度快于生态环境的发展速度;汉中市城市化与生态环境复合系统的协调度较低,表现为协调性总体上处于失调状态。在汉中市未来经济发展中,需要强化生态环境保护意识。
