摘　　要：探究城市群空间联系格局演变不仅有助于揭示城市空间发展特征,也可为城市群空间结构优化、区域经济社会协同发展提供科学依据。文章以环长株潭城市群为例,基于时序全局主成分分析法评估城市发展质量,采用修正距离要素的引力和潜力模型量化城市群的发展状况以及空间联系作用,综合运用ArcGIS的反距离插值法和重心转移曲线分析2005—2019年环长株潭城市群的8个城市空间联系的时空分异及演化趋势。结果表明:①2005—2019年环长株潭城市群城市联系作用总体呈稳定增长态势,存在“中部高、西部低”的强度差异;②2005—2019年环长株潭潜力重心总体上的移动方向为由西北向东南移动,但潜力重心偏移角度小,且相对接近几何中心,表明城市之间的空间相互作用保持均衡稳定性发展;③环长株潭城市群总体已形成长沙—株洲—湘潭三角结构的强联系区域,与外围城市的空间联系偏弱。应统筹优化区域发展格局,形成较完备的城市群体系,进一步优化资源配置,加快城市群综合交通基础设施网络建设,创新一体化合作机制,加快城市全面提质发展,提升城市群整体实力。Exploring the evolution of the spatial connection pattern of urban agglomerations not only helps to reveal the characteristics of urban spatial development,but also provides guidance for the optimization of urban agglomeration spatial planning and the coordinated development of regional economy and society.Taking 8 cities around the Changsha-Zhuzhou-Xiangtan urban agglomeration as an example,this paper evaluates the quality of urban development based on the time series global principal component analysis method,adopts the gravity and potential model of modified distance elements to quantify the spatial connection effect of cities,and comprehensively uses the inverse distance weight method and gravity center shift of ArcGIS to analyze the spatio-temporal differentiation and evolution trend of the spatial connections of eight cities around the Changsha-Zhuzhou-Xiangtan urban agglomeration from 2005 to 2019.The results show that:1)The total urban linkages of the Changsha-Zhuzhou-Xiangtan urban agglomeration shows a steady growth from 2005 to 2019,with a difference in intensity of"high in the middle and low in the west".2)The gravity center of potential distributes in the southeast of geometric center and moves in the city center of Changsha,which indicates that it has the strong spatial agglomeration in Changsha City.The gravity center of potential shifts from the northwest to the southeast and is close to the geometric center,but the offset angel is small,which indicates that the spatial interaction between cities keeps stable development.3)It has basically formed a strong triangle-structure connection among Changsha,Zhuzhou and Xiangtan,8 cities have a weak connection with other five cities.It puts forward that it is necessary to coordinate and optimize regional development patterns,form a relatively complete system of urban agglomeration,further optimize resource allocation,speed up the construction of comprehensive transportation infrastructure networks in urban agglomeration,innovate the cooperation mechanism,a
