摘要/Abstract

摘要： 绿洲城镇组群是新疆特殊区域形成的规模相对较小的单一中心空间自组织模式。运用城市中心性指数、城市经济联系模型和Theil系数对新疆八大绿洲城镇组群内部城镇中心性、经济联系及空间差异测度。结果显示：绿洲城镇组群内部的中心城市的中心性职能较强，周边城镇的中心性职能相对较弱，形成了单中心的空间自组织模式；绿洲城镇组群内部经济联系量和经济联系隶属度大小的排序一致，离中心城市的距离越近、经济发展水平越高，经济联系隶属度越高；近10 a年来绿洲城镇组群的整体空间差异一直在扩大，且呈现出继续扩大趋势。在此基础上，提出了建立区域合作协调机制、明确城镇组群发展方向、增强中心城市的辐射带动作用、实现产业合理分工以及构建制度保障体系促进绿洲城镇组群的协同发展。

Abstract: Recently，improving coordinated development of internal town group has been paid more and more attention along with the new urban agglomeration development strategy. Accelerating the coordinated development of small and medium-sized cities and small towns is an important task of implementing regional coordinated development strategy. The oasis town group in Xinjiang is a relatively small and single geographical unit, with a spatial self-organized mode. The urban centrality index, urban economic connection model and Theil coefficient are applied to measure the centrality, economic connections and spatial differences of the eight oasis town groups in Xinjiang. The results demonstrate that the central cities in the oasis town groups always have strong central functions, and the central functions of the surrounding towns are relatively weak. These organizing patterns generated the single center of the spatial self-organizing mode in Xinjiang. The inter-regional economic connection inside the oasis town group was mainly dependent on the distance from a town to the central city. The oasis towns which are closer to the central city, will achieve the higher economic development levels, as well as the higher membership degree of economic relations. In the last decade, the overall spatial variation of the oasis town groups showed an expanding trend, and this trend was continuing. Based on the results, the regional cooperation coordination mechanism should be established to define the development direction of urban group and to strengthen the diffusive and driving role of central cities, as well as to realize the rational division of industry. Solving these problems effectively will be of great help for Xinjiang to harmonize coordinated development in oasis town groups.
