摘要
根据新疆叶尔羌河流域地下水均衡场裸地潜水蒸发的试验观测资料，提出了进行潜水蒸发系数计算的反Ｌｏｇｉｓｔｉｃ公式，同时采用可变多面体法对公式进行了非线性拟合。该公式较全面地反映了潜水蒸发系数的变化规律，简单实用。
Based on the experimental data of phreatic evaporation from bare soil in the groundwater balance station in Yerqiang River Basin in Xinjiang , the Inverse-Logistic Formula is presented. Variable Polyhedron Method is applied for the nonlinear regression. The results show that this formula can reflect the change of Phreatic Evaporation Coefficient more exactly and it is easy for application. Therefor, It is fit for the estimation of phreatic evaporation in this area.
