摘要
以1988年、1992年及2001年3个时相的Landsat TM/ETM+遥感影像为数据源,分别提取了3个年份的焦作市建成区范围和面积,并叠加分析得到了1988-2001年间建城区的空间扩展情况.研究结果表明,1992年后焦作市进入快速发展阶段,城市大幅度向南部高新区扩展;由于焦作市受到北部太行山限制和东西两翼煤矿区的影响,建城区在空间扩展方向上形成其特殊的形态:整体发展趋势呈现以向南为主、向东西适度发展的"T"字形格局.
The boundary and area of urbanization of Jiaozuo are obtained respectively from three - stage Landsat images of 1988, 1992 and 2001. The expansion of urbanization area acquired and compared by means of GIS overlaying analysis. The results show that Jiaozuo had a fast development since 1992. The urban area expanded quickly towards the new hi -tech zone, and the spatial expansion of Jiaozuo urbanization area take on a special ＂T＂ configuration. The expansion is mainly toward the south and moderately toward the east or the west, because it is blocked off by the northward Tai - hang mountain and coal mining area in the east - west.
