Abstract
Urban spatial structure is one of the major research fields in urban planning and development.Currently,regional economies are becoming the main form of urban development in urban agglomeration comprehensive development.The capital circle is a typical city group,which has a center of the capital.Many scholars have selected this region as the objective for carrying out researches on urban pattern fields.In this paper we analyzed the major cities along Beijing-Tianjin-Tanggu,Beijing-Tangshan-Qinhuangdao and three axes of the capital circle based on remote sensing technology.The urban spatial structure from 1980s to 2008 is analyzed in three aspects,i.e.the spatial structure of the cities and towns system,spatial distribution of road infrastructure,and dynamic analysis of urban expansion.The three aspects of the dynamic urban expansion are discussed in detail,including the quantitative description of urban expansion and spatial variation,occupation of land areas for expansion characteristics,and the evolution trend of urban spatial form.The paper reveals the spatial law of urban development,and provides support for international city construction of Beijing and its regional development planning.The results show that all the cities and towns along the three axes extended from the center of the city.Expansion and concentration between the cities have showed significant radiation effects and directionality.Spatial patterns of urban expansion have been increasingly complex.At the same time,urban expansion and development along the three axes have been different.The cities and towns along south-west axis of Beijing-Baoding-Shijiazhuang have been the most densely distributed.The means of transportation along the axis of Beijing-Tianjin-Tanggu have been most developed.And obvious changes occurred in the scale and rate of urban expansion along the axis of Beijing-Tianjin-Tanggu,followed by the south-west axis of Beijing-Baoding-Shijiazhuang.
