皖江城市带国土空间利用效率与高质量发展的时空耦合

国土空间利用效率是区域经济社会发展质量的指示要素，与高质量发展的时空耦合关系对推进区域协同发展具有重要影响。在主体功能区划基础上，综合应用超效率模型、空间分类、空间自相关和耦合协调模型，揭示皖江城市带2011—2019年国土空间利用效率和高质量发展的耦合关系。结果表明：（1）皖江城市带重点开发区的国土空间利用效率明显大于重点生态功能区和国家农产品主产区，年度差距呈现重点开发区>国家农产品主产区>重点生态功能区的时序分异格局。（2）国土空间利用高效率区集中分布在芜湖周围，且高值集聚现象逐渐被打散，一般效率区主要分布在安庆和池州辖区内，低效率区逐渐向北迁移，覆盖滁州等地。（3）国土空间利用效率与高质量发展的全局空间相关作用由负转正，局部空间关联主要以显著HH区和显著LL区为主，显著HH区主要分布在皖江城市带的东南地带，显著LL区集中分布在北部地区，集聚范围有所扩大。（4）国土空间利用效率和高质量发展的耦合协调水平逐渐提升，城镇空间的耦合协调度趋向低度协调，农业空间由高度磨合向高度协调过渡，生态空间逐渐转向低度协调，综合水平的耦合协调度始终较高。

Spatio-temporal coupling relationship between territory spatial utilization efficiency and high-quality development in Wanjiang City Belt

The territory spatial utilization efficiency is an important element of the quality of regional economic and social development, and the spatio-temporal coupling relationship with high-quality development has an important impact on the realization of regional coordinated development. Therefore, on the basis of the planning of the main function area, the Super-SBM model, spatial classification, ESDA and coupling coordination model were used to reveal the coupling relationship between the territory spatial utilization efficiency and high-quality development in Wanjiang City Belt from 2011 to 2019. The conclusions can be drawn as follows. (1) The territory spatial utilization efficiency of key development areas was significantly greater than that of key ecological function zones and the main national agricultural products production areas, and the temporal differentiation pattern showed that the gap between the key development zones was the largest, followed by the main national agricultural production areas, and the key ecological function zones were the smallest. (2) In terms of spatial distribution, the high-efficiency areas were concentrated around Wuhu, and the phenomenon of high-value agglomeration was gradually dispersed, the general-efficiency areas were mainly distributed in Anqing and Chizhou, and the low-efficiency areas gradually moved northward to Chuzhou. (3) As for spatial correlation characteristics, the global spatial correlation of the two major systems changed from negative to positive from 2011 to 2019. The local spatial correlation was mainly based on the significant HH areas and the significant LL areas, and the significant HH areas were mainly distributed in the southeast of the Wanjiang City Belt, the significant LL areas were concentrated in the northern part and the agglomeration range had been expanded. (4) From the view of the characteristics, the level of coupling and coordination of territory spatial utilization efficiency and high-quality development in different spaces has gradually increased. Furthermore, the degree of coupling and coordination of urban space tended to be low level, the agricultural space transitions from a high-running-in to a high-coordination, the ecological space gradually turned to low-coordination, and the comprehensive level of coordination had been in a high-degree stage.
