| 摘 要： | 建立了城市土地利用效率与城市环境的综合评价指标体系,利用因子分析法,借鉴物理学中的耦合度函数,测算了1998～2008年四川省地级城市土地利用效率与环境之间的耦合协调程度。结果表明,四川省地级城市环境与城市土地利用效率的协调程度虽然逐步提高,但是总体上水平不高;只有改善环境与提高土地利用效率并举,才能提高二者的协调度。

| Abstract: | A comprehensive evaluation index system about city land utilization efficiency and urban environment was built.The coupling degree in Prefecture-level Cities of Sichuan Province from 1998 to 2008 was estimated with factor analysis method and the Physics coupling function.The results showed that the coupling degree between city land utilization efficiency and urban environment was gradually increased,but the overall level was not high.Only to improve the environment and improve the land utilization efficienc... |
