| 摘 要： | 我国北方灌溉农田区土壤水分空间差异较大,一维水分模型无法计算土壤水分的空间分布,本研究在V isualBasic环境下结合ArcOb jects控件技术,利用ArcG IS的空间分析能力,开发出一个基于G IS的三维区域土壤水运动模型。该模型以R ichards方程和Van Genuchten公式为基础,通过简单的数据输入及参数设定便能快速的计算出土壤含水量、土壤导水率和土壤水势,对土壤水分空间运动进行模拟,并分别利用参考文献数据及实测数据对模型进行验证,证明计算结果可靠。

| Abstract: | The spatial variation of soil moisture in irrigation field is often significant in the North of China.However,one-dimension model of soil water movement can not describe the spatial distribution of soil moisture.This study developed a three-dimension model of soil water movement using capability of spatial analysis in ArcGIS,which was built on Visual Basic and ArcObject.The Richards' equation and Van Genuchten formula were used to calculate the soil water retention,soil hydraulic conductivity and soil water potential,respectively,through simple data input and parameter setting,and afterwards the spatial movement of soil water was simulated.The model was validated using both experiment data and corresponding data from literature to confirm the reliability of the calculating flow. |
