摘要: 论文基于GIS平台及探索性空间数据分析方法(Exploratory Spatial Data Analysis, ESDA)和脱钩模型,以地级行政单元为对象,分析2000—2013年长江经济带建设用地扩张、经济增长的时空差异及脱钩关系。研究表明:1)近15 a来,长江经济带建设用地扩张与经济增长具有明显的阶段性和区域性。热点分析显示,建设用地增长热点区呈扩散效应,冷点区逐渐缩小。而经济增长的冷、热点区演变格局与建设用地并不同步。2)2000—2013年,长江经济带建设用地扩张与经济增长耦合关系经历了“增长负脱钩、弱脱钩”为主—“弱脱钩”为主—“弱脱钩、增长连结”为主的变化过程。分析表明,近15 a来长江经济带建设用地扩张与经济增长脱钩程度整体趋于优化,其中,负脱钩类型的城市数量降低17.76%,而脱钩类型数量上升11.22%。3)脱钩程度的空间异质性分析显示,长江经济带各时期的城市扩张与经济增长脱钩关系具有弱空间集聚性。总体上,长三角城市群较长江中游、成渝及滇、黔城市群的脱钩程度表现更优。脱钩程度变化机制与城市产业结构、用地效率和用地模式等密切相关。加强土地利用规划管控力度、严格用途管制规则,引导城市精明增长,走内涵式新型城镇化道路是改变经济发展对建设用地扩张依赖的重要途径。

Abstract: The decoupling relationship between construction land expansion and economic growth and its heterogeneity during 2000-2013 in the Yangtze Economic Belt (YEB) are analyzed at the prefecture-level administrative units based on GIS platform, Exploratory Spatial Data Analysis (ESDA) method and decoupling model. The results indicate that: 1) In recent 15 years, the construction land expansion and the economic growth in the YEB had distinctive stages and regional characteristics. Hot spot analysis shows that the hot spots of construction land growth were diffusive and cold spots of construction land growth gradually shrank. However, the evolution pattern of hot spots and cold spots of economic growth was not in step with the evolution pattern of construction land. 2) During 2000-2013, the coupling relationship between construction land expansion and economic growth in the YEB experienced from the processes of “negative decoupling and weak decoupling” to “weak decoupling” and “weak decoupling and coupling”. According to the calculation, the cities with “negative decoupling” accounted for 12.15% of all cites in the Yangtze River Delta during 2010-2013, decreasing 17.76% compared to the stage from 2000 to 2005. Meanwhile, the cities with “weak decoupling” and “strong decoupling” account for 65.42% of all cites in the Yangtze River Delta during 2010-2013, rising 11.22% compared to the stage from 2000 to 2005. On the whole, the decoupling degree between construction land expansion and economic growth in the YEB improved in recent 15 years. 3) Spatial heterogeneity analysis of decoupling degree indicates that the decoupling relationship between urban expansion and economic growth in the YEB presented weak spatial autocorrelation in all stages. Generally, the decoupling degree of city clusters in the Yangtze River Delta was gradually increasing, better than the decoupling degree of city clusters along the middle reaches of the Yangtze River and city clusters of Chengdu-Chongqing and Yunnan-Guizhou. The evolution mechanism of decoupling degree was closely connected with urban industrial structure, land use efficiency and land use mode.
