汉江生态经济带的生态保护屏障主体功能在城镇化进程的快速推进下逐步退化,探究其城镇化建设与生态环境系统的协调发展问题尤为必要.基于汉江生态经济带13个地市2009-2017年的统计数据,利用耦合协调度模型、空间自相关模型等,分析城镇化与生态环境系统耦合协调发展的时空演化规律及空间集聚效应.结果表明:汉江生态经济带城镇化发展指数与生态环境指数呈稳中上升趋势,系统相对发展类型自2011年后表现为“生态环境滞后型”; 耦合协调等级出现“拮抗—磨合”“失调型—过渡型”的转变,区域耦合协调水平呈现“核心—边缘”特征的空间分布差异; 各城市系统耦合协调路径呈协同发展态势,区域内空间关联性、集聚性效果显著,HH集聚型城市逐年增加,但是,驻马店市、南阳市与随州市显示不存在空间相关性.

The main function of the ecological protection barrier of the Hanjiang ecological economic belt has gradually degraded under the rapid progress of urbanization. It is of great strategic importance to explore the coordination between urbanization and ecological environment for the realization of regional sustainable development. Based on the statistical data of 13 cities in the Hanjiang Ecological Economic Belt from 2009 to 2017, the coupling coordination model and spatial autocorrelation model were used to analyze the spatiotemporal evolution laws and spatial agglomeration effects of the urbanization and ecological environment system coupling and coordinated development.Results show that the urbanization development index and the Eco-environment index of the Hanjiang Eco-economic Belt are steadily increasing, and the relative development type of the system has been "ecological environment lagging type" since 2011.The coupling and coordination level appears "antagonism-running" and "imbalanced type-transitional type", the regional coupling and coordination level presents the spatial distribution difference of the "core-edge" feature; the coupling and coordination path of each city system shows a synergistic development trend, the spatial correlation, and the agglomeration effect in the region are significant.The HH agglomeration cities year by year increase, but there is no spatial correlation in Zhumadian City, Nanyang City and Suizhou City.
