摘要: 小麦是我国重要的粮食作物之一,小麦干旱灾害严重影响我国粮食安全,因此对小麦干旱的评估显得尤为重要。自然水分亏缺率模型是评估小麦干旱状况的主要模型之一,该模型涉及数据类型多,模型计算复杂,影响模型的实际应用。本文利用GIS建模工具ModelBuilder建立自然水分亏缺率模型的GIS逻辑计算模型。研究结果表明:基于GIS的小麦自然水分亏缺干旱评估模型,将复杂的数学模型转变为方便快捷的GIS栅格计算,实现了模型计算过程的自动化、一体化、空间可视化,同时模型逻辑关系清晰,便于数据修改维护。

Abstract: Wheat is one of the important food crops in China.Wheat drought disasters affect food security seriously in China.Assessing wheat drought is particularly important.Nature water stress model is one of the main model of the evaluation of wheat drought conditions.This model involves lots of data types,model calculation is complicated,affecting the actual application of the model.The natural water stress model is established into GIS logical calculation model by ModelBuilder.The results showed that the natural water stress drought evaluation models based on GIS transformed complex mathematical model into simple GIS grid computing.It realized counting process automation,intergration,spatial visualization.And the model has a clear convenient for modification,maintenance of data.

Key words: GIS, drought, nature water stress model, ModelBuilder
