浅析浙中地质灾害风险评价与风险管理

Analysis on Risk Evaluation and Risk Management of Geological Disasters in Central Zhejiang

浙江省以丘陵山地为主,同时地处沿海常年受梅雨、台风等影响,地质灾害频发,种类也较多。如何科学地开展地质灾害防治并优化人类与自然之间的关系是目前需应对和提升的问题。因此本文在地质灾害风险评价和风险管理定义基础上,运用地理信息系统(GIS)评价方法和基于地质灾害风险防范区管理方法,并举以实际案例,对地质灾害风险评价和风险管理在浙中地质灾害领域的应用进行研究分析并得出结论。

Zhejiang province is mainly hilly and mountainous, and located in the coastal area, which is affected by plum rain and typhoon all the year round. Geological disasters are frequent and there are many types. How to scientifically carry out geological disaster prevention and optimize the relationship between human and nature is a problem that needs to be addressed and improved at present. On the basis of the definition of geological hazard risk assessment and risk management, this paper applies the Geographic Information System (GIS) assessment method and the management method based on the geological hazard risk prevention zone, and takes the actual case, simultaneously analyzes the geological disaster risk assessment and risk management of geological hazards field of central Zhejiang, and finally draws a conclusion.
