| 摘 要： | 研究了一种遥感监测城市边缘区的方法.首先利用遥感影像提取城市用地.其次,用窗口平滑算法计算城市用地比例.再次,将城市用地比例作为分级标志,依据洛斯乌姆的区域城市结构理论,对城市结构进行划分.最后,从划分结果中提取城市边缘区.研究利用北京市1984—2007年间8期的Landsat5TM影像,应用本文的方法,对城市边缘区进行了界定,验证了方法的可行性.

| Abstract: | A method to divide urban fringe by remote sensing was designed.Urban land was extracted from remote sensing data;its proportion was calculated using a smoothing window algorithm;Urban structure was divided based on the regional city structure theory of L.H.Russwurm;Urban fringe was extracted from divided urban structure.This method was used to divide urban fringe in Beijing by using 8periods of Landsat5TM images from 1984to 2007.Data showed that the present method is quite practicable. |
