为快速简单确定新疆库尔勒市包头湖研究区盐碱土土壤水分特征曲线，采用张力计法对研究区土试样进行了水吸力和对应水含量的测量。基于 RETC 主要的4种模型，分别模拟计算得到了盐碱土的土壤水分特征曲线，并对模型的拟合值与实测值进行线性回归分析，确定了最优土壤水分特征曲线拟合模型为 van Genuchten (VG)。

To quickly and easily obtain the soil water retention curve in Xinjiang Baotouhu test area,the tension method was applied to measure water suction and corresponding water content in soil samples in the test area.Based on 4 models in RETC software,the soil water characteristic curve of salinealkali soil were obtained by simulation analysis respectively,and simulated accordance value and measured value were analyzed with linear regression egation.It was concluded that accordance model of optimal soil water char-acteristic curve was van Genuchten (VG).
