| 摘 要： | 通过构建城市化综合指数和生态环境综合指数的指标体系,利用协调发展度模型,对甘肃省1990-2006年城市化与生态环境耦合演化的趋势进行量化分析。结果表明:甘肃省城市化指数和生态环境指数都呈线性增长,协调发展度指数也呈现一种线形的上升趋势。从城市化综合指数和生态环境综合指数曲线看出,2003年以前城市化发展滞后于生态环境建设,导致甘肃城市化与生态环境耦合协调一直以中低度协调为主。当城市化发展到一定阶段,生态环境也会有所改善,两者的耦合关系才会逐渐增强。

| Abstract: | Through setting up index system of urbanization synthetical index and eco-environment synthetical index and using the coordinative degree model,quantitative analysis on the evolution trend of coupling between urbanization and eco-environment in Gansu province from 1990 to 2006.The results showed that: urbanization index and eco-environment index increasing linearly,the coordinated development index between urbanization and eco-environment fluctuated from 1990 to 2006,but the index showed a liner upward tren... |
