摘要
以Landsat TM/OLI遥感影像为数据源,将武汉市土地利用分类情况主要分为建成区、植被、水体三类。通过统计对比2003~2015年的各类土地面积变化发现,武汉市建成区的面积呈逐年增加的趋势。结合分析各类统计数据得出影响武汉市城区扩张的驱动力因子中,地理环境、交通因素和人口因素为其扩张的基础条件,经济结构的转变是推动主城区向外扩张的内在动力,宏观规划政策的调控起着外在的引导作用。
Based on Landsat TM ／OLI remote sensing imagery, the land use conditions of Wuhan are supervised classified to buih -uparea, vegetation area and water area. The change of various kinds of land area are counted and compared. The built - up area of Wu-han was increasing every year. Combining with the analysis of various kinds of statistical data from the driving force factors of Wuhanurban expansion, the geographical environment, traffic and population factors are the foundation factors are the foundation conditionsin urban expanding, the transformation of economic structure is the inner motive power of push the main outward expansion, macroplanning policy out regulation plays a guiding role.
