摘要
以徐州城市为例,将城市区域划分为东、西、南、北、中、东北、西北、东南、西南9个空间单元,运用多时相卫星遥感TM图像和Matlab软件技术,对建成区扩展的动态变化数据进行了监测.结果表明,徐州城市建成区总面积在不断扩展,1994年前徐州西部矿区建成区扩展程度在城市扩展贡献上占有重要地位,但1994年后徐州南部因无污染源又是人文景观区而成为城市扩展上的优势区域.
Taking Xuzhou city for example, probing the method of dividing the urban region in 9 spatial units that is east, west, south, north, center, northeast, northwest, southeast and southwest, their dynamic changes of construction area growth were monitored using the techniques of multi-temporal landsat thematic mapper (TM) satellite remote sensing images and matlab (matrix laboratory).The results indicate that the total construction area of Xuzhou urban is growing continuously, the construction area growth of west mining area in Xuzhou makse up important poison before 1994, but after 1994, the south in Xuzhou urban region due to not only no pollution source but also human landscape spot, and become the superior region for urban growth.
