摘要
以新疆阿克苏市为研究区域，利用1997～2008年的调查资料和统计数据，构建了城市化与生态环境协调发展的综合指标体系。在对城市化综合水平与生态环境综合质量进行测度的基础上，运用层次分析法计算了城市化与生态环境协调度。结果显示：1997年以来，阿克苏市城市化综合水平逐步提高，而生态环境综合质量呈现出波动性的变化特征，即1997～1999年阿克苏市生态环境综合指数具有上升趋势，生态环境质量较好；从1999年到2008年期间生态环境综合指数除了2005年呈上升趋势外其他年份都呈现下降趋势，表明生态环境质量有所变化且向不协调的方向发展。从协调度分析可知，12年中有5年轻度失调，三年中度失调，三年勉强协调，一年严重失调，总体来说，阿克苏市的城市化与生态环境还处于不协调状态。
During the process of urban development, there is an interaction between the city and eco-environment, and at the same time the relationship is a continuous contradictious development. Due to the conflicts of urban development and eco-environment, it is necessary to make a deep analysis of the urban eco-environmental problem, to find the root cause of urban problems and to propose a solution. This paper, taking Aksu city as the study area, used 1997-2008 survey data and statistics to construct a comprehensive index system of urbanization and coordinated development of eco-environment, and to measure the integration of urbanization and comprehensive eco-environment quality by AHP method. We also calculated coordination degree of urbanization and eco-environment. The results showed that since 1997, Aksu city has had a gradual growth in the comprehensive level of urbanization. However, the comprehensive eco environment quality showed an upward trend in the eco-environment index from 1997 to 1999, and that eco-environment quality improved. The eco-environment index showed a downward trend in the period 1999 -2008 except for an upward trend in 2005. According to the analysis of the coordination degree in the 12 years, there are five years of light non-coordination, three years of moderate coordination, three years of slight non-coordination and one year of serious non-coordi- nation, which is due to the speeding up of the industrialization process, and the increase of ＂three wastes＂ resulting from industrialization, thus a sharp decline in the coordination degree of eco-environment and urbanization. On the whole, the current trends of urban ecoenvironmental quality are in the state of insecurity and deterioration. In the future, we should strengthen environmental governance and focus on the eco-environmental protection to build a resource-saving city. At the same time, we should enforce standards of environmental quality and ＇three wastes＇. Furthermore, we should enhance environmental aware- ness in various social groups so that people have a better understanding of the current problems.
