| 摘 要： | 随着中国城市化进程的加快,城镇用地在迅速地扩大,如何快速、准确与客观地提取城镇用地信息,对土地资源的保护和可持续利用具有十分重要的意义.综合运用归一化建筑指数（NDBI）,归一化植被指数（NDVI）和修正型归一化水体指数（MNDWI）进行RGB彩色合成,然后对合成图进行HIS变换,利用H和S分量进行城镇用地信息提取.并利用TM7,TM5,TM1彩色合成图的I和H分量进行裸土噪声去除,最终获得城镇用地信息专题图.专题图的总体精度、Kappa系数、生产者精度和用户精度分别为：92%、0.84、88%和96%,证实该方法是快速提取城镇用地切实有效的方法.

| Abstract: | With the acceleration of urbanization,urban land-use is increasing rapidly in China.Abstracting urban land-use information rapidly,accurately and objectively is very significant for the protection and sustainable exploitation of land resources.In this research,the normalized difference of built-up index(NDBI),the normalized difference of vegetation index(NDVI) and the modified normalized difference of water index(MNDWI) were applied in RGB colour composition.The composed image was then transformed by HIS.Th... |
