干旱区绿洲城市城市化与生态环境耦合--以乌鲁木齐为例

Analysis of the Coupling Rule Between Urbanization and Eco-environment in Arid Region Oasis—— Taking Urumqi as an example

本文以乌鲁木齐为例,利用灰色关联方法,对干旱区绿洲城市的城市化进程和生态环境响应的耦合关系进行评价与分析,在乌鲁木齐城市化对生态环境的影响过程中,空间城市化对生态环境的作用最为明显,社会城市化和经济城市化对生态环境的作用相对小一些,而人口城市化对生态环境的关联度仅为0.59,对于干旱区绿洲城市来说人口对于生态环境的影响最小;生态环境对城市化的束缚作用主要表现为大气、水、土环境产生不同程度的胁迫效应,资源能源、生态条件对于城市化的制约和限制作用最为明显,生态环境综合治理对于城市化进程起着很大的促进作用,生态环境污染对于干旱区绿洲城市的胁迫作用相对较小。最后得出结论:乌鲁木齐市城市化与生态环境的耦合目前正处于缓慢变化阶段,属于逐步磨合型。

Taking Urumqi as an example, the coupling degree model of urbanization and ecological environment has been put forward, which was divided into coupling degree function and coupling coordination degree function. The results showed that：space -urbanization affecting the ecological environment is the most obvious, society urbanization and economy urbanization smaller relatively, but the population urbanizes is minimum ; energy resource and the ecological condition affecting the urbanization are the most obvious , ecological environment comprehensive treatment is bigger comparatively, and environmental pollution effect is minimal. Coming to a conclusion finally： coupling of urbanization and ecological environment in Urumqi is being in the slow change stage.
