| 摘 要： | 应用指标回归法和定性（风速和相对湿度）定量（吹程）资料，建立了蒸发皿系数Kp计算方程，并用黄河下游引黄灌区48个观测站实测资料进行了验证计算。计算结果表明，应用该方程，可大大改善Kp值的计算精度。

| Abstract: | Evaporation is an important factor of the hydrologic cycle.Its accurate estimation is necessary for many hydrology studies.An equation for predicting K P was developed using the indicator regression approach with both categorical(wind speed and relative humidity)and quantitative(fetch length)data.The verification shows that the predicted K P values by developed equation are better than the existing equations. |
