摘　　要：结合滦河流域2处典型水文站近50a蒸发皿观测资料,对滦河流域水面蒸发变化特征进行趋势显著性检验并对其变化成因进行分析。结果表明,近50a滦河流域水面蒸发总体呈现递增变化,水面蒸发递增率分别为18.9mm/10 a和14.3 mm/10 a,夏季水面蒸发量增大是其年蒸发递增的主因。气温对流域水面蒸发影响较大,不同季节下的相关度均较高。Based on the observation data of evaporation dishes from two typical hydrological stations in the Luanhe River Basin over the past 50 years,a trend significance test was conducted on the characteristics of water surface evaporation changes in the Luanhe River Basin,and the causes of these changes were analyzed.The results show that the overall water surface evaporation in the Luanhe River Basin has shown an increasing trend in the past 50 years,with an increase rate of 18.9 mm/10 a and 14.3 mm/10 a respectively.The increase in water surface evaporation in summer is the main reason for its annual evaporation increase.The temperature has a significant impact on water surface evaporation in the watershed,and the correlation is high regardless of the season.
