摘　　要：Saxton模型能估算较多土壤水分特征参数且考虑容重、砾石和盐分影响而被广泛应用于农业、水文等领域。研究基于Saxton模型及IDL(Interactive data language)语言开发土壤水分特征软件平台,利用土壤属性数据进行土壤水分特征栅格计算,实现空间制图,有效解决水文运动模型模拟应用过程中栅格化土壤水分特征参数缺乏问题。该平台软件界面友好,操作简单易行高效,既可为现有模型应用提供输入参数,也可作为单独模块嵌入已有软件中使用,具有较好兼容性。Saxton model can be used to estimate many soil water characteristic parameters and to consider density, gravel and salinity effects. It was widely used in agricultural, hydrology and other domains. This study was based Saxton model, using visualization language IDL （Interactive data language） had developed a software platform, able to use soil moisture characteristics of soil attribute data grid computing, able to spatial mapping, effectively solved hydrological model simulates of the movement lack of grid soil moisture characteristic parameters in application. The platform has a good interface, easy to operating, can provide input parameters for the application of existing models and also be embedded into existing software as a standalone module.
