The development and construction of regional landslide stability intelligent assessment system in order to achieve effective risk assessment and management of landslide hazard are subject of great theoretical value and practical significance.Based on Matlab graphical user interface development environment（GUIDE）

fuzzy comprehensive evaluation was used as the main algorithm of the assessment system.Eight evaluation parameters such as rock strength

rock integrity coefficient

groundwater

precipitation

slope angle

blasting vibration

weathering and alteration

as well as human activities factor were chosen and their weights were assigned respectively.Gaussian function and S-shaped function were chosen as the membership functions of the parameters.The regional landslide stability GUI evaluation system was developed and applied to Wangjiaping landslide engineering for evaluation demonstration.The results show that the system implements the multiple factors′ comprehensive evaluation on Wangjiaping landslide stability and classifies the level of landslide hazard.The system provides a new processing tool for regional landslide engineering analysis evaluation.
