利用作物生长机理模型) ) ) AquaCro p 模型, 建立作物生长环境要素( 气象、土壤水分等) 与产量之间的定量关 系, 以此构建农业旱灾损失定量评估模型, 并对云南省曲靖市沾益县一季中稻的旱灾损失进行了实例计算。结果表 明, AquaCr op 模型能够客观地评估农业因旱损失, 为旱灾风险分析计算提供灾损数据支撑。 关键词: AquaCrop 模型; 干旱灾害; 农业损失评估; 因旱作物减产率

T he AquaCro p model, based on t he mechanism o f cr op g rowth pr ocess, was intro duced to develop the quantitativ e rela2 tionship betw een cro p environmental facto rs( w eather, so il mo isture, etc) and cr op yields, and t hen to construct a quantitat ive e2 v aluatio n model o f the agr icultural dr ought losses. The model w as a pplied to calculate the ag r icultural dr ought losses o f seaso n rice in Zhanyi County o f Qujing City in Yunnan Prov ince. The results showed that the AquaCro p mo del can assess the agr icul2 tur al droug ht losses objectiv ely and pr ov ide data suppor t for dr ought r isk analysis.
