摘　　要：风险性、脆弱性、恢复性和适应性是自然灾害4个最重要的特性,也是灾害研究的主要方向。灾后恢复作为减灾管理的关键环节具有重要的研究意义。基于自然灾害系统理论,归纳整理了重庆旱灾报刊数据库,构建并分析了重庆旱灾系统,探讨了其灾后恢复性模式。结果表明:(1)重庆2006年特大旱灾百年一遇,伏旱是导致灾情累加形成巨灾的直接原因;(2)旱灾后的连续降雨是提高灾后恢复力的重要因素;(3)灾民的外出打工实现了旱灾的风险转移和经济补偿,减小了损失。这些研究结果为水田农业区的伏旱型旱灾系统研究和恢复性措施提供了新的思路和实证。Risk,vulnerability,resilience and adaptability are the most important natures of disaster,and they are the main research content in disaster field.As a key step in disaster reduction management,disaster resilience has an important meaning.Based on disaster system theory,this paper sums up and sorts out Chongqing's drought system database,constructs and analyzes Chongqing's drought system and discusses the drought resilience model.The results are as follows:(1) The drought spread in Chongqing in 2006 is a severe event happening once a century,and the summer drought is the direct cause that lead to accumulative disaster situation and catastrophe formation;(2) Continuous rainfall is the important factor that improves the ability of resilience after drought;(3) Victim's going out to work as a casual labourer brings about risk transfer and economic compensation and reduces losses.The research provides a new thought for the study on disaster system and resilience measure of the continuous summer drought caused by sustained high temperature in paddy planting area.
