摘要
利用英吉沙国家气象观测站二级站1965—2009年小型蒸发皿蒸发量资料,采用气候倾向率和气候趋势系数方法分析了英吉沙蒸发量的变化趋势及引起蒸发量变化的气象因子,结果表明,英吉沙年和各季蒸发量均存在明显的减小趋势。影响蒸发量变化的因子主要有日照、风速、相对湿度和降水量。
Based on the evaporation data of Yingjisha weather station from 1965 to 2009, we analyzed the variation trend of evaporation and the factors caused the evaporation variation with the methods of climate trend coefficient and climate tendency ratio. The results showed that the annual, seasonal and monthly evaporation variation had presented obvious downtrend in recent 45 years. The main impact factors were the sunshine, wind speed, relative humidity and precipitation.
