摘要
利用系统科学理论,以长江中游城市群为研究对象,从国土空间生产、生活和生态功能协调作用的视角出发,利用2006—2014年长江中游城市群31市的统计数据,选择了熵—TOPSIS模型及耦合协调度模型进行协调性评价,揭示了城市群国土空间协调利用的时空特征,并运用泰尔系数深入剖析了协调度区域差异的来源。结果显示:在时序演变上,城市群总体协调水平呈现波动上升的趋势,协调类型处于濒临失调与勉强协调;在空间上,初级协调和勉强协调的城市大多分布于长江沿线,呈现出带状分布,并围绕中心城市集聚;子都市圈内差异对整个城市群协调度总体差异变化的贡献明显大于都市圈之间差异,而武汉城市圈内城市之间差异对城市群总体差异影响最大。
Taking urban agglomeration in the middle reaches of the Yangtze River as the example of study,from the perspective of‘production-living-ecological’functions coordination,based on system science theory,using the statistics of 31 cities in the urban agglomeration from 2006 to 2014 years,the Entropy-TOPSIS model and the coupling coordination model,we evaluated the coordination,so as to reveal the spatial and temporal characteristics of the coordinated utilization of geographical space in the urban agglomeration.Then,where the regional difference of coordination degree comes from has been analyzed by Theil coefficient.The results showed that in the evolution of time series,the coordination level of the urban agglomeration fluctuates and rises,and the coordination type is on the verge of maladjustment and barely coordinated;in space,the primary coordinated and barely coordinated cities mostly distribute along the Yangtze River,showing a zonal distribution and the gathering around the central cities.The contribution of the difference among zones to the overall variation of the whole urban agglo meration is obviously greater than that of the intraregional difference,while the difference among cities in Wuhan urban agglomeration has the greatest impact on the overall difference of urban agglomeration in the middle reaches of the Yangtze River.
