摘要/Abstract

摘要： 利用始于1953年的蒙自气候站小型蒸发器和始于1986年的E-601B型蒸发器蒸发量观测资料，计算两种蒸发器蒸发量的折算系数，并与相关分析及线性拟合的结果进行对比分析。结果表明：蒙自站小型蒸发器与E-601B型蒸发器蒸发量的时程分配基本一致，两者之间具有较好的相关关系，线性拟合的线性系数与折算系数较为一致，且检验结果较为接近，推算出该地区两种仪器年蒸发量的折算系数为0.65。研究结果可用于本地区的气候评价、水量平衡分析、水资源调查等。

Abstract: Based on an evaporation data from small evaporation pan since 1953 and an E-601B pan since 1986 at Mengzi station, conversion coefficient between them was calculated. Correlation analysis and linear fitting were also applied to estimate the conversion coefficient, and conversion coefficients calculating by two methods were compared. The results show that evaporation characteristics are identical based on small evaporation pan and E-601B pan at Mengzi, and both correlations are significant. Their linear coefficients and conversion coefficients are also same, and testing results are close. Conversion coefficient of annual evaporation between two pans is 0.65 at Mengzi. The results from this study could be used in climate evaluation, water balance analysis and water resources investigation and so on in this region.

Key words: Evaporation, Conversion coefficient, Linear fitting, A E-601B evaporation pan, Mengzi region
