中文摘要:

水面蒸发是表征流域水文循环的重要指标.依据主成分分析原理以及统计学相关分析方法,对海河流域中部平原区的水面蒸发试验观测数据进行分析.结果表明:气温和风速是影响该地区水面蒸发的主要因子.在月时间尺度上,日均水面蒸发量和气温具有的显著的正相关性,而在日时间尺度上与蒸发量的相关性不明显;风速无论在月时间尺度还是在日时间尺度上都与水面蒸发量呈显著的正相关性.此外,风速对蒸发量影响的大小还与蒸发量的基础值有关,基础值越大,风速对其的影响越大.最后,根据观测得到的昼、夜蒸发量数据分析了水面蒸发量的昼夜组成,数据显示该地区昼蒸发量和夜蒸发量的差别不大,分别占日蒸发量的52.2%和47.8%.

英文摘要:

Water surface evaporation is an important indicator of hydrological cycle in specific watershed.Based on the principle of main component analysis and statistical correlation analysis method,the water surface evaporation data was analyzed in the central plain of Haihe River basin.The results showed that air temperature and wind speed were the dominated factors effecting water surface evaporation in this area.In monthly scale,there was significant positive correlation between daily mean water surface evaporat...
