利用作物生长机理模型---AquaCrop 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， AquaCrop 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。
利用作物生長機理模型---AquaCrop 模型，建立作物生長環境要素(氣象、土壤水分等)與產量之間的定量關繫，以此構建農業旱災損失定量評估模型，併對雲南省麯靖市霑益縣一季中稻的旱災損失進行瞭實例計算。結果錶明， AquaCrop 模型能夠客觀地評估農業因旱損失，為旱災風險分析計算提供災損數據支撐。

T he AquaCrop model, based on t he mechanism of crop growth process, was introduced to develop the quantitative rela-tionship betw een crop environmental factors( w eather, soil moisture, etc) and crop yields, and t hen to construct a quantitat ive e-valuation model of the agricultural drought losses. The model w as applied to calculate the agricultural drought losses of season rice in Zhanyi County of Qujing City in Yunnan Province. The results showed that the AquaCrop model can assess the agricul-tural drought losses objectively and provide data support for drought risk analysis.
