| 摘 要： | 为了探讨本溪山区水面蒸发量的变化特征和影响水面蒸发的主要气象因子，利用本溪市草河口气象站1953-2010年E601小型蒸发皿蒸发量、气温、降水、日照时数、相对湿度、风速和水汽压等气候资料，运用灰色关联度分析法对影响蒸发的主要气象要素进行统计分析。结果表明，本溪山区水面蒸发与气温、降水和水汽压关系比较密切，与日照时数、相对湿度和风速相关较差。影响水面蒸发的主要气象因子从大到小的排列顺序为：气温＞水汽压＞降水量＞日照时数＞相对湿度＞风速。如果年平均气温升高1℃，年水面蒸发将增大66 mm；年降水量增大10 mm，水面蒸发将减少2.7 mm；年相对湿度增大1%，水面蒸发将减少16 mm；年平均风速增大1 m/s，水面蒸发量将减少154 mm。本研究揭示了主要气象因子对本溪山区水面蒸发量的影响程度，为山区水资源进一步合理开发利用提供科学的依据。

| Abstract: | In order to explore characteristics of change of the water surface evaporation in Benxi mountainous area and the main meteorological factors affecting the evaporation of water surface,based on climate data of E601 evaporation tank,temperature,precipitation,sunshine duration,relative humidity,wind speed and vapor pressure in Caohekou weather station in Benxi from 1953 to 2010,by using gray relational analysis and statistical analysis of the main meteorological factors affecting evaporation..The results showed that the evaporation of water surface and temperature,precipitation and vapor pressure relations were more closely,and sunshine hours,relative humidity and wind speed related to poor in Benxi mountainous area.The evaporation of water surface in the main meteorological factors in descending order as follows：temperature vapor pressure precipitation sunshine duration relative humidity wind speed.If the annual average temperature increases 1℃,the annual evaporation of water surface would increase by 66 mm;annual precipitation increased by 10 mm,the surface evaporation would reduce 2.7 mm;1% annual relative humidity increased,the evaporation of water surface would be reduced by 16 mm;annual average wind speed increased to 1 m/s,and surface evaporation would be reduced by 154 mm.This study revealed the main meteorological factors on the degree of influence of surface evaporation in Benxi mountainous area,water resources for further rational development and utilization to provide a scientific basis. |
