Abstract :
The statistic analysis mothed is used to analyze the region landlside susceptibility in landslide hazard analysis. In the mothod, landslide invetntory and the data of enviromental factors which induce landslides are essential. The Cameron Highlands of Malaysia was selected as the experimental studying area. Based on GIS and the Bivariate statistical analysis mothod, the relationships among landslides and environmental factors were analyzed. Then, Probability Index Model and Distance Evaluation Model were developed. The comparison and assessment of two models show that they have higher prediction precision and universality. The effect of Distance Evaluation Model is better than that of Probability Index Model.
