中国洪涝灾害发生的频率、范围、损失程度近年来急剧上升,对农业生产、农民生活乃至整个国民经济持续稳定发展造成直接冲击与巨大毁损。恢复力作为描述人类自身响应和发挥主体能力、积极抵御和适应外界变化的指标,与受灾体脆弱性一起构成灾害管理学不可或缺的重要因素。对农业洪涝灾害受灾体脆弱性及灾后恢复力概念进行新的定义,分析二者紧密相连又互为影响的关系,并详细分析阐述气候条件、水系分布、地貌特征、土壤与植被覆盖状况、耕地面积与结构和水土流失状况等自然环境因素,农户收入、劳动力数量、区域经济发展水平、人口规模与密度、水利设施状况、农户心理素质和文化素质等社会经济因素,以及政府组织管理、社会援助等因素对农业洪涝灾害受灾体脆弱性、恢复力的影响,为农业防灾减灾工作提供理论和决策依据。
The frequency and scope of flood disasters and the loss caused by them have risen sharply in recent years, which has directly impacted and hugely ruined the Chinese agricultural production, peasants" life and sustained stable development of the whole national economy. Resilience, as an index which depicts how human beings response, bring their capability of being subject into play and actively resist and adapt to external changes, and vulnerability both are the indispensable important factors of the science of disaster management. The vulnerability of the bodies stricken by agricultural flood disasters and the post-disaster resilience are both redefined; their relationship of mutual connection and mutual influence is analyzed; the effect of natural environmental factors, such as climate, water distribution, geomorphic features, soil and vegetation cover, arable area and structure, soil erosion, etc., that of social and economic factors, such as peasant households" income, labor force, regional economic conditions, population size and density, water facilities, psychological and cultural quality of peasant households, etc., and that of other factors, such as governmental organization and administration, social aids, etc. on the vulnerability and resilience of the bodies stricken by agricultural flood disasters are explained in detail, which provides both disaster Drevention and mitigation. theoretical and decision-making bases for agricultural
