云南省水、陆面蒸发量计算方法的初步研究

A Preliminary Study on Calculation Method for Water and Land Surface Evaporative Capacity in Yunnan Province

采用本文提出的方法 ,计算了全省各站历年各旬的水面蒸发量、历年各月的陆面蒸发量。计算结果的精度能达到水文部门的乙级标准 ,表明文中所涉及的地面太阳总辐射量的计算、海拔高度对蒸发影响的订正、参数Ct的确定以及布德科公式适用范围的修改 。

Based on the climate data from 1951 to 2000 in the 125 meteorological stations in Yunnan Province, the water and land surface evaporation capacities were calculated, by using the method developed by the authors in this paper. The precision of the calculated results reached at the second standard promulgated by hydrological authorities. The results showed that the method had an application value in the calculation method of total solar radiation, revising of evaporation by altitude, selection of Ct and revising of suitable application conditions of the Buderk formula.
