| Abstract: | After some factors affecting geo-hazards occurrence, including natural geological conditions, evocated factors, etc. are discussed, we have established an evaluation index system. On the GIS platform, the statistical weight method and fuzzy comprehensive judgement method are adopted for geo-hazards risk evaluation and division. Then, two prediction results are compared with each other on figures and lists. The ultimate evaluation result is consistent with actual situation. |
