| 摘 要： | 造成水面蒸发气象要素变化的因素多而复杂，用单一的线性关系选择预报因子建立预报方程有可能把较好的预报因子漏掉。根据成因分析的方法，寻找预报对象与预报因子之间的物理联系，采用单相关系数的计算、比较，确定优化预报因子建立多元回归预报方程，这样选择到的预报因子更符合实际，建立的预报方程具有较好的拟合效果。

| Abstract: | There are many factors which cause the change of water surface evaporation elements. When the prognostic equation is set up with forecasters selected by single linear relationship, the better forecaster maybe missed. This paper bases on the cause of formation, searches the physics of relation in forecast object and forecaster, adopts the calculation and contrast method of single correlation coefficient, establishes the multiple regression equation by using various types of functions to compute the correlation coefficient. The forecaster selected by this method will be more conformable to reality and the prognostic equation will be of fitter results. |
