选取浙江省平阳县气象观测站2010年全年气象观测资料,采用通径分析方法和多元线性回归理论,对平阳县气象站20 cm小型蒸发皿蒸发量及其相关气象影响因子进行分析。结果表明：日蒸发量与日均气温、日均风速和日照时数呈正相关,与日均相对湿度呈负相关。影响日蒸发量的因子中,日照时数无论其单独作用或与除日均风速外的其他气象因子的协同作用都较大;日均气温85%以上主要表现在直接作用上;日均相对湿度与日照时数的协同作用最大;日均风速影响小主要体现在与其他要素的协同作用上。根据影响蒸发量的主要因素,建立相应的多元回归模型,并检验有一定的可靠性。

Based on meteorological data about 2010 in meteorological station of Pingyang County in Zhejiang Province,path analysis and multiple linear regression were applied to understand the changes in pan evaporation and relation with meteorological factors in the paper.The results showed that the factors of evaporation were positive correlation to average air temperature,wind velocity and sunshine durations.The average relative humidity and evaporation were negative correlation.Otherwise the influence of the sunshine durations on evaporation was larger whether its effect directly or synergistic effect with other factors in addition to wind velocity.The influence of the average air temperature was more than 85% in direct effect.The synergistic effect of relative humidity with others was largest.The influence of wind velocity was smaller mainly in synergistic effect with others.On the other hand,multivariate regression model was built on the basis of the main impacting factors about the evaporation,and the test results showed that the model was certain reliability.
