摘要
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。
The AquaCrop model, based on the mechanism of crop growth process, was introduced to develop the quantitative relationship between crop environmental factors（weather, soil moisture, etc） and crop yields, and then to construct a quantitative e- valuation model of the agricultural drought losses. The model was 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.
