The vulnerability of hazard bearing bodies is the key to reveal the drought disaster mechanism and risk mechanism.From the micro perspective of households,based on survey on 210 households farmers affected in the southwest area,and by using ordered choice model,effects of five major household livelihood assets by the inte-gration of household characteristics on household drought vulnerability are studied.The research results show that:drought vulnerability of households is significantly affected by natural,human,financial and material assets.A-mong them,the first three ones have a significant negative effect on household drought frail,but there is a negative correlation between material assets and household drought vulnerability.%承灾体的脆弱性是揭示旱灾成灾机理和灾害风险机制的关键，从农户家庭的微观视角出发，以西南地区的210户受灾农户的调查为基础，采用排序选择模型，研究由农户家庭特征整合而成的五大农户生计资产对农户家庭的旱灾脆弱性的影响。研究结果显示：自然、人力、金融、物质资产对农户家庭的旱灾脆弱性有显著性影响。其中，自然、人力和金融资产对农户家庭旱灾脆弱性有显著负效应，而物质资产与农户家庭旱灾脆弱性存在负相关关系。
