苏锡常地区的城市化及其资源环境胁迫作用

城市化是当今世界发展的重要特征，城市化的发展在促进社会进步的同时也对生态环境产生了一系列负面影响。以苏锡常地区为案例，从城镇数量的变化、城镇规模的变化、经济结构的转换以及非农业人口比例的变化这4个方面分析了该地区的城市化特征和过程，并对其生态环境胁迫作用进行了定性和定量的分析。结果表明：苏锡常地区城市化的速度快、程度高，其带来的资源环境胁迫作用是很明显的。

Urbanization in SWC Region and Its Ecological Stresses

Urbanization has been one of the most important characteristics of global development. It plays a very important role in promoting the social development, whereas some negative effects for the eco-environment was brought out. The Suzhou-Wuxi-Changzhou (SWC) Region is taken as a case study in this paper. At first, we studied the urbanization process and its characteristics, based on changes in town number, town area, economic pattern and proportion of non-agricultural population. Then we analyzed the ecological stresses of the rapid urbanization process qualitatively and quantitatively. The results show that the urbanization process of SWC Region is very fast and its urbanization level is very high. And its ecological stresses become more and more serious with the urbanization of this region.
