| 摘 要： | 选定徐州市中心城区作为研究区域，应用多时相Landsat TM／ETM＋遥感影像为数据源，利用支持向量机（SVM）分类器分别对1994、2000、2005年三个时相的遥感图像进行土地覆盖分类，并在Fragstats3．3景观格局软件平台上，基于景观尺度对徐州市景观格局进行全面的分析，分析结果表明：2005年徐州市景观整体较1994年具有更大的破碎度、更高的多样性和更低的聚集度，景观的类型与格局变化受到人为因素的影响较大；不透水面层逐渐取代耕地和城市绿地。

| Abstract: | In this paper,Xuzhou City was taken as the study area and multi-temporal Landsat TM/ETM+ were used as data source.The SVM classifier of ENVI was used to land cover classification for three temporal remote sensing images.The result indicated that SVM classification had certain reliability.Then,the landscape of Xuzhou was analyzed by the land metrics of Fragstats 3.3.The result,Xuzhou City in 2005 than in 1994 overall landscape greater fragmentation,higher diversity and lower degree of aggregation,landscape c... |
