| 摘 要： | 正确认识天山北坡城市群的空间组织结构以及空间发展形态，对于完善绿洲城市群的发展理论和规划具有重要意义。以天山北坡城市群为研究对象，通过资源环境承载力的分析，总结出未来城市群发展面临的客观制约因素；通过中心性分析、断裂点理论修正的Voronoi多边形等方法识别出城市群的中心城市及各自的辐射范围城市；通过引力模型识别出城市之间的社会经济联系强度。据此，利用多维尺度分析的方法，可视化地展现了天山北坡城市群发展的空间组织形态。经调查了解：（1）乌鲁木齐市与克拉玛依市是未来城市群发展的两个中心城市，五家渠市、阜康市、昌吉市、石河子市周边目前属于乌鲁木齐市的辐射范围城市，奎屯市，乌苏市属于克拉玛依市的辐射范围城市；（2）城市群内部的城市之间的联系比较松散，特别是两个中心城市之间联系较弱；（3）城市群的空间发展形态为串珠式，是一种特殊的走廊式空间形态。

| Abstract: | Oasis urban agglomerations have distinctive spatial organizations and morphology with other urban agglomerations as their special landforms and environmental restricts.So how to understand the particularity of oasis urban agglomeration development,and then put forward the suitable development suggestions is an important issue.This paper takes urban agglomeration on the north slope of the Tianshan Mountains as an example,aiming to identify the particular development mode of this representative arid urban agglomeration.Many statistical models and methods were used to interpret the spatial organizations.To be mentioned,visualization of urban agglomeration’s spatial morphology was innovatively made in this paper.There are three steps to identify the spatial organization of the urban agglomerations.First,central cities in this region should be picked up.Here,centricity analysis method was used to identify central cities in this region.Indices such as GDP,population in each city,urbanization rate,employee in the third industry,and so on,were considered,and then entropy method was used to integrate these indices and got centricity of each city.Two cities,whose centricities were much higher than others,were chosen as central cities in this urban agglomeration.Second,spatial impact regions of each central city need to be divided.Method of Voronoi polygons revised by breaking point theory was used to divide spatial and economic affected areas of two central cities.The breaking point theory tried to find the dividing point between two central cities by considering population,industry,spatial distances,and so on.This dividing point can well represent cities’ social and economic radiation threshold.Then,referenced the dividing point,Voronoi polygons were made to divide the spatial impact regions of each central city.Third,spatial organizations of this urban agglomerations should be visualized.Interaction model was used to identify social and economic interaction intensity among the cities.Accordingly,multi-dimension analysis was adopted to visualize spatial morphology of urban agglomerations based on the interaction intensity.From the visualization map,the urban agglomeration’s spatial morphology was easily seen as beads-strings.The agglomeration morphology has not been formed yet,but some urban groups.Considered the special land forms and its strict environmental restrictions,this paper suggests that the further development pattern should be compact along the main traffic roads.Accordingly,several conclusions were got as follows:(1) Two central cities exist in this agglomeration as the remote distances between cities,Urumuqi and Karamay.The urban agglomeration on the north slope of th Tianshan mountains has not formed yet,there are still several urban groups developed.(2) The interactions between cities,especially between two central cities,are still weak due to remote distances.(3) Spatial morphology of this urban agglomeration is beads-strings,one special kind of corridor type,which may be representative for oasis urban agglomeration.Cities should take compact development mode to protect limited recourses and environment,and also information technology and modern traffic way should be adopted to shorten the distance between cities. |
