The study of karst collapses is still in macroscopic and qualitative level right now. The PLS Path Model adopts the iteration solution of monogenesis or multivariant linear regression, does not need to hypothesize the probability distribution of observation variables. In this model the requirement of sample point capacitance is very loose, and the problem that the model can not be recognized does not exist, so it is an effective linearity statistics modeling method. In this paper, based on the analysis of the influence factors for karst collapses in Wuhan and GIS technique, the PLS Path Modle is used to forecast the hazard potentiality of karst collapse in Wuhan city with a good results. It is found that the application of this model could get good effictiveness and this model should be adopted widely.
