The analysis of the comprehensive level coordination degree between the urbanization and eco-environment system in Aksu city
阿克苏市城市化与生态环境综合水平协调度评析

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-coordination, 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 eco-environmental 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 awareness in various social groups so that people have a better understanding of the current problems.
