【摘要】：随着新型城镇化的推进,城镇化发展过程中面临着严重的生态环境胁迫压力,开展城镇化与生态环境耦合协调度研究,对新疆的可持续发展提供理论与方法支撑.基于熵值法与层次分析法构建新疆城镇化指数和生态环境指数,然后基于耦合协调度模型定量分析新疆各地、州、市城镇化与生态环境的耦合协调度,最后分析新疆城镇化与生态环境耦合空间分布特征.结果表明:1)2014年新疆城镇化与生态环境综合指数为0.29和0.42,总体水平较低;2)2014年新疆14个地、州、市城镇化与生态环境发展耦合协调度在0.41~0.64之间,跨越低、中2个级别,分别占地、州、市数量的46.7%和53.3%;3)从空间分布看,2014年新疆14个地、州、市城镇化与生态环境发展的耦合度存在地域差异性,表现为北疆优于东疆,南疆最低.
[Abstract]:With the development of new urbanization, the development of urbanization is faced with serious stress of ecological environment. The study of the coupling coordination between urbanization and ecological environment provides theoretical and methodological support for the sustainable development of Xinjiang. Based on entropy method and analytic hierarchy process (AHP), the urbanization index and ecological environment index in Xinjiang are constructed, and then the coupling coordination degree between urbanization and ecological environment is quantitatively analyzed based on the coupling coordination degree model. Finally, the spatial distribution characteristics of urbanization and ecological environment coupling in Xinjiang are analyzed. The results show that the comprehensive indexes of urbanization and ecological environment in Xinjiang in 2014 are 0.29 and 0.42, and the overall level is relatively low. 2) in 2014, the degree of coordination between urbanization and ecological environment development in 14 places, states and cities of Xinjiang is between 0.41 and 0.64. 46.7% of the total number of prefectures and cities and 53.3% of the total number of cities in Xinjiang in 2014, there were regional differences in the coupling degree between urbanization and ecological environment development in 14 places, states and cities in Xinjiang in 2014, showing that the northern Xinjiang was superior to the eastern Xinjiang, and the southern Xinjiang was the lowest.
