摘要
通过现有实测资料的插补和延长,用水面蒸发折算系数法估算了民丰县地表水面蒸发量。并根据蒸发量计算结果,分析了水面蒸发的区域分布、年内和年际变化等情况。结果表明,在低温湿润地区,水面蒸发量小,高温干燥地区,水面蒸发量大;蒸发的年内分配不均匀,水面蒸发量年际变化较稳定。
By the interpolation of the measured data and to extend the existing, using evaporation from water surface conversion coefficient method to estimate the venture the surface of the water e- vaporation. And evaporation from water surface is analysed according to the result of evaporation ca- pacity calculation of regional distribution, years and interannual variability, and so on and so forth. Results show that the low temperature wet regions, water surface evaporation quantity is small, high temperature and dry area, water surface evaporation; Uneven distribution of evaporation of the years, the water evaporation interannual variability is stable.
