【摘要】 自然灾害不是简单的自然事件或过程,它是致灾因子和承灾体的脆弱性共同作用的结果。从本质上看,自然灾害是人地耦合系统失衡的表现,是人地关系不协调的反映。灾害导致的人口迁移是人类面临灾害风险的一种适应性对策。灾害移民可分为灾前移民和灾后移民,或可返回性移民和不可返回性移民。自然灾害并非必然意味着人口迁移。灾害移民是受诸多宏观因素和家庭因素影响,在灾害诱导下产生的一种人口被迫迁移。在汶川8.0级地震灾后重建过程中,可运用相关灾害移民理论指导灾区移民和人口安置工作。更多还原

【Abstract】 Natural disasters are not simply a natural event or process,but the result of destructive agents imposed on hazard bearer in vulnerable conditions.In essence,natural hazards are an embodiment of the unbalanced combined man-environment system and a reflection of disharmony in man-environment relations.Migration has been a major adaptive strategy for humans when facing hazard risks.Natural hazards can never mean migration at all.Hazard-induced migration is triggered by hazards under certain macro-conditions and influenced by household characteristics.During post-disaster recovery after Wenchuan Earthquake,past theories on hazard-induced migration may be relevant for resettlement work.更多还原
