Abstract Abstract The purpose of this paper is to describe the techniques of urban land use classification of TM image for land use investigation in Zheng Yuan county, Guizhou Province, where is a typical karst mountain area, with many land use types scattering in. The authors also discuss the result and its accurate, and introduce some simple methods of improving the accurate of classification. A geographical information system for land management (SK set 2.0) was set up and the result of the investigation was compared and examinated. It shows that the accurate of the investigation is good.
