摘　　要：基于城市研究领域已被广泛应用的断裂点理论,以兰州都市圈为主要研究对象,试图对《甘肃省城镇体系规划(2013~2030年)》提出的兰州都市圈空间结构进行定量优化.首先,利用断裂点理论得到兰州中心城区到周边8座相邻城市的断裂点位置,然后连接各断裂点确定兰州市的引力吸引范围,再分别计算周边8座城市对兰州市的空间辐射强度,并依据兰州市城市吸引范围与已规划兰州都市圈范围不重叠区域的面积大小以及形态走势,分析兰州都市圈空间向外拓展的主要发展趋势,最后,根据兰州市引力范围与都市圈空间发展趋势的趋同特征,提出了兰州都市圈空间结构优化的构想.Based on the breaking point theory which has been widely used in the field of urban research,this paper takes Lanzhou metropolitan area as the main research object and tries to quantitatively optimize the spatial structure of Lanzhou metropolitan area proposed in “Urban System Planning of Gansu Province(2013~2030)”.Firstly,the location of the breaking points from the central area of Lanzhou to eight neighboring cities is obtained by using the breaking point theory.Then,the attraction range of Lanzhou is determined by linking the breaking points,and the spatial radiation intensity of the eight neighboring cities to Lanzhou is calculated respectively.According to the area size and shape trend of non overlapping area between Lanzhou attraction area and planned Lanzhou metropolitan area,the main development trend of Lanzhou metropolitan area outward space expanding is analyzed.Finally,based on the convergence characteristics of Lanzhou attraction area and the spatial development trend of the metropolitan area,the idea of spatial structure optimization of Lanzhou metropolitan area is put forward.
