摘要
The landslide factors have been extracted in Tianshui area by statistic method. According to the parameters from mulvariate logistic regressive formula, it is utilized for the function of spatial analysis and modeling to establish the model for landslides in research area, to measure the influence degree of landslide factors, and to draw the map showing the risk assessment for landslide in Tianshui. The landslide factors will increase accordingly when resolution are changed from 1
