Abstract Twenty nine karst drainages are chosen for analysis of the five factors which affect the growth of geomorphologic type,and the choice is based on the TM image,CBERS image and DEM data which are extracted by use of RS and GIS techniques and from the ASTER image of Guizhou Province.This research procedure includes the extraction of 24 indices,data processing and multivariate regression analysis by means of softwares SPSS and MATLAB and proposing the mathmatical models for recognition of different geomorphologic type of karst drainage and then the very good recognational effect can be obtained through varience analysis and sample zone checking.
