【摘要】：以GIS为软件平台,基于3个时期(1987年、2000年、2009年)的遥感影像和5个年代的历史地图,利用扩展强度指数、放射状指数和空间重心转移模型等方法,计算1912～2009年呼和浩特市区城市空间形态参数,在时间和空间上定量分析呼和浩特市近百年来城市扩展时空特征、城市形状演化特征和空间重心转移特征,进而研究呼和浩特市的城市形态演化过程及其特征.研究结果表明,1912～1948年呼和浩特市区从西南到西北方向缓慢发展,城市形状由"正方形"趋向星形;1948～1973年,随着城市化进程的发展,市区一直向东北快速发展,城市形状从星形向圆形演化;1973～1987年,市区空间向西南方向加速发展;1987～2000年,城市空间向东北逐渐发展;1973～2000年,城市形状在圆形和矩形之间浮动,变化相对稳定;2000～2009年,城市建设再次进入快速扩展期,市区向东南方向扩展,城市形状趋于矩形.
[Abstract]:Based on the remote sensing images of three periods (1987, 2000, 2009) and the historical maps of five decades, the extended intensity index, radial index and spatial barycenter transfer model are used in GIS software platform.The spatial parameters of urban space in Hohhot from 1912 to 2009 were calculated, and the spatial and temporal characteristics of urban expansion, the evolution of urban shape and the transfer of spatial center of gravity in Huhhot were analyzed quantitatively in time and space.Then the evolution process and characteristics of urban morphology in Hohhot are studied.The results show that the urban area of Hohhot develops slowly from southwest to northwest from 1912 to 1948, and the shape of the city moves from "square" to "star" from 1948-1973. With the development of urbanization, the urban area has been developing rapidly to the northeast.Urban shape evolves from star to circle from 1973 to 1987, urban space accelerates to southwest direction from 1987 to 2000, urban space gradually develops to northeast from 1973 to 2000. The shape of city fluctuates between circle and rectangle, and the change is relatively stable from 2000 to 2009.Urban construction once again entered a period of rapid expansion, urban expansion to the southeast direction, the shape of the city tends to rectangle.
