农业旱灾承灾体恢复力的影响因素——基于野外土地利用测量与入户调查

恢复力作为刻画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，在灾害学领域的引入进一步丰富和明晰了灾害承灾体的性质，与脆弱性具有同等的重要性。但当前对灾害恢复力的研究不足，如何界定灾害恢复力的特征、诊断和定量评价恢复力尚存在较大的探讨空间。在湖南鼎城高排河流域野外土地利用现状测量与入户调查所得数据和气象数据的基础上，应用数学统计方法重点分析了土地利用、农户经济、文化素质状况等因素与农业旱灾承灾体恢复力的关系。结果表明，地貌类型与海拔高度从较大尺度上决定了农业旱灾承灾体恢复力的大小，水源地位置及其蓄水能力、水田与旱地的比例关系、劳动力文化水平、农户实际年收入和非农收入比例是影响农业旱灾承灾体恢复力的主要因素。

ON INFLUENCE FACTORS OF AGRICULTURAL DROUGHT RESILIENCE——ANALYSIS BASED ON LAND USE INVESTIGATION AND HOME INQUIRY DATA

As an index of abilities of response,resistance and adaptation to the change of environment,resilience,which play the same role with vulnerability(another attribute of hazard-affected body),enriched and defined exactly the characteristics of hazard-affected bodies when it was introduced to the field of natural disaster.It is urgent to study on resilience,such as how to define natural disaster resilience,diagnose and evaluate it,because of little researches on them at present.Based on land use investigation ...
