Study and Application of Landslide Disaster Refinement Forecast System in District Level Based on GIS

摘要

Landslide is one of the most serious geological disasters, and the most effective way to prevent Landslide disaster is forecast. In this paper, landslide disaster regionalization model induced by effective precipitation is used through analyzing in-depth landslide disaster risk rating regionalization models, and implemented landslide disaster refinement forecast system in district level based on GIS secondary development approach. The main function of system is to achieve the result of landslide disaster risk rating forecast and landslide disaster information management. The forecasting results obtained by the system can provide a scientific basis for the local government departments such as planning measures on prevention and mitigation disaster. While the forecasting results are also published to the public, which can help the public take response timely and reduce losses.
