Preventive resettlement and risk reduction strategy analysis in disaster risk management system

摘要

Preventive resettlement is one of the effective measures to prevent geological disasters. However, there is a lack of definite theoretical system to guide how to deal with the potential disasters and risks and provide migration decision-making. The paper selects disaster risk management as the theoretical guidance and the risk assessment of the framework system as the focus to explore hazard identification and characterization, identification of exposed elements, vulnerability assessment and determination of risk levels, through which the paper gets risk cognition and obtains the basis for risk management. Besides, the paper combines with the different characteristics and factors of geological disasters to expound on the strategy of risk reduction and put forward the possible solutions to avoid and alleviate risks. Furthermore, under certain conditions, the disaster-avoiding migration strategy is adopted.
