摘要

APPIA 是用于非饱和土壤物理特性数据处理的专用软件，可快速分析非饱和土壤持水曲线和导水曲线并给出相关参数。系统分析了 APPIA 的数理基础，并对不同方法分析的结果进行了比较。结果表明：用 APPIA 程序可获得较为准确的非饱和土壤物理参数，应广泛推广使用。

Abstract

APPIA is a special software for unsaturated soil physical properties determination

and can rapidly analyze unsaturated soil water retention curve

and conductivity curve and provide with relative parameters. The mathematical and physical base of APPIA is analyzed and the results predicted by different method are compared. The result shows corrected unsaturated soil physical parameters can be got by APPIA. So the software of APPIA should be spreaded widely.
