| Abstract: | The paper introduces a method of land use survey with the assistance of professional RS software,with which we can obtain the land use change information by multi-sources RS fusion technique on the basis of SPOT and ETM+ data in the year 2002 and 2003 and change the rust scope and aimless land use change survey into land survey in purpose,thus realizing the technique of creative land use change survey in the city of Huhehaote,and at the same time providing a new way of land use change survey for other regions in the future. |
