【摘要】 从微现农户角度分析了干旱、农业旱灾和农户旱灾脆弱性的成因。文章认为，自然降水不足或与作物需求匹配不均是造成农业干旱的动力，农户对干旱的应付能力不足是导致干旱成灾的原因。这种应付能力既受区域水资源可利用量的限制，也与农户的作物种植结构、灌溉支付能力、风险认识和对农业的依赖程度有关。农户旱灾脆弱性既与农业干旱有关，又受到人均资源和收入、种植和消费结构、生态环境质量、政策、巾场价格等多重因素的作用。最脆弱的农户是那些人均资源占有量最小且收入最少的农户。更多还原

【Abstract】 Based on the micro -farmhouse management, the paper analyzs the causes offormulation of fannhouses’ agricultural drought disaster vulnerability. It is pointed out that nat-ural restrictions are the root of farInhouses’ agricultural disaster vulnerability. While the differ-ences in labor-capital, risk perception, the structure of crops and consumption, the quality ofecological environment, economic policy and agri-production price etc. have great indirect effects on the vulnerability. The most vulnerable farmhouses are those which both per-capitalnatural resources and income are the lowest. Reducing farmhouses’ economic press, improvingrisk awareness and using the natural resources reasonably are the guarantee of agriculturaldisaster mitigation.更多还原
