%X On the basis of the project work for dynamic monitoring of land_use change in mountainous area by utilizing technologies of remote sensing, GIS and GPS, framework of quantitative and statistical analysis procedure is presented in this paper. Attentions has been paid to core technical issues such as band selection for image subtraction and changing threshold selection, in order to derive proper change information from TM image data. Compare between basic approaches for image change detection, i.e., comparative analysis of multitemporal classified data, and simultaneous analysis of multitemporal data, is also provided. In the research process, GPS surveying data has played an important role.
