| 摘 要： | 利用平顶山市1961—2009年蒸发量及温度、日照时数、风速、水汽压等资料,初步分析了平顶山市蒸发量的年代(际)、年、季、月的变化特征、趋势及引起蒸发量变化的因子。结果表明:平顶山市年代、年、季和月蒸发量均存在明显的下降趋势,偏少趋势主要表现在春、夏2季,其中6月偏少趋势最明显;影响蒸发量变化的主要因子有温度、日照、风速、水汽压等,蒸发量与日照时数、平均风速呈显著正相关,与温度、水汽压呈负相关,它们是造成蒸发量变化的主要因子。

| Abstract: | Based on evaporation and temperature,sunshine duration and wind speed,vapor pressure and other materials in pingdingshan from 1961 to 2009,the analysis have been made about the inter-annual,annual,seasonal and monthly variation characteristics,tendency and factors causing of evaporative capacity variation.The results showed that the inter-annual,annual,seasonal and monthly evaporative capacity showed the decreasing trend mainly in spring and summer and the most sensitive month was June.The main factors that affect evaporative capacity changes were temperature,sunlight,wind speed,vapor pressure and so on,evaporative capacity was positively correlated with sunshine duration and average wind speed,but negatively correlated with temperature,vapor pressure,this showed that they were the main factors causing evaporative capacity variation. |
