基于人地关系的自然灾害风险形成机制分析
Natural Disaster Risk Formation Mechanism Based on Man-land Relationship
摘要
Abstract
Natural disaster risk formation mechanism is the foundation of disaster risk evaluation and risk management,but the research is insufficient.Based on disaster system theory,this paper puts forward that disaster occurred place,disaster force and disaster body work together to affect the occurrence of disaster risk.Firstly,disaster occurred place is the place disaster risk happens.Secondly,disaster force is the force natural events acting on disaster body.Thirdly,the exposure and resistance of disaster body are the decisive factors on disaster risk.And disaster risk is the result by the conflict of human activity and disaster event in the race for space from the view of man-land relationship.When disaster force is more powerful than resistance of disaster body,disaster risk could happen.Risk is determined by disaster force,resistance of disaster body and its exposure.According to man-land conflict theory,the core of disaster risk management is coordination relationship of man and disaster,which can be achieved by coordination relationship of human relation.关键词
