水面蒸发模型的进一步优化

水面蒸发量是水文水利计算、径流分析预测及水资源利用评价的主要内容,针对目前水面蒸发计算模型存在的问题,通过对水面蒸发机理的分析,采用最小二乘回归法,建立了由主要影响因子构成的修正系数函数对由相对次要因子构成的主体函数进行修正的基本模型,经比较,该模型具有较好的拟合精度。

Optimization of water surface evaporation model

water surface evaporation is the main content for water hydrologic calculation,runoff analysis and forecast,and the water resources evaluation.Aimed at the present existing problems of evaporation calculation model,through the mechanism analysis for the water surface evaporation,using the least squares regression method,the paper established the basic model which was modified by the correction factor function composed from the main factors to the main function composed from the relatively minor factor.By co...
