| 摘 要： | 基于中巴资源卫星遥感影像数据,利用比值植被指数对徐州市2001年,2005年,2008年3年的建设用地覆盖情况进行提取,探究比值植被指数应用于建设用地提取的可行性。通过比较2001—2008年间建设用地变化情况,发现徐州建设用地覆盖呈增长趋势,2005—2008年较2001—2005年增速稍缓。结果表明,利用比值植被指数对遥感影像分析,可以快速地获取建设用地覆盖变化情况,为未来几年发展的预测与规划提供参考。

| Abstract: | This paper discusses the possibility of using ratio vegetation index(RVI) in the analysis of construction land cover change.Based on the CBERS data,the paper uses RVI to extract land cover data of construction land in Xuzhou City in the years of 2001,2005 and 2008.A comparison between the land cover change data from 2001 to 2008,the paper finds out that the construction land cover change of Xuzhou had an increasing tendency from 2001 to 2008 and the increment speed from 2005 to 2008 was less than that from 2001 to 2005.The results show that construction land cover change can be quickly obtained by using the remote sensing images processed by RVI,which provides the reference to the development of Xuzhou in the future. |
