摘要
Geological hazard evaluation is an objective need for sustainable development of small towns.The essay took Yuzhong County in Gansu Province as an example to introduce establishment of three-grade fuzzy mathematical model for evaluation of geological hazard,and a comprehensive and detailed system of evaluation index.By means of this geological model,the author made an assessment of to the identified geological disasters including landslides,avalanches,landslides and unstable slopes in study area.The results show that Yuzhong County fall into the high-prone areas of geological disasters if the possibilities of assessed hazards are classified into four classes: non-prone,low-prone,prone and high-prone,it is consistent with the actual situation.
