Description
Summary:Monitoring land use status timely is the basis of rational management of land resource, and the important gist for planning agriculture or even the whole national economy. Possessing the advantages of macroscopic information, real time, periodicity and integrity, remote sensing provide the possibility for monitoring land use quickly, objectively and precisely. This research uses CART algorithm to draw knowledge automatically, and extracts classification image of the trial zone to analyze land use change in Xiangxi river watershed. It was concluded that Land use was unreasonable utilized at Xiangxi River basin in recently years, vegetation and the maintenance of water and soil were destroyed in a certain extent.
