E601型蒸发站在群库勒水文站的应用探讨

Discussion on Application of E601 Evaporation Station Qunkule Hydrological Station

以新疆阿勒泰地区布尔津县冲乎尔镇群库勒水文站为例,进行测站2019年7月~10月蒸发量人工观测值与E601型蒸发站观测值的比测分析。结果表明,蒸发量人工观测和蒸发站观测绝对误差在0.5 mm及0.2 mm以内的天数分别为109 d和84 d,分别占总观测天数的88.62%和68.29%,符合《水面蒸发观测规范》的要求,而且人工观测和蒸发站观测有效比测数据的相关性分析表明,人工观测和蒸发站观测的日蒸发量值线性相关关系良好,群库勒水文站基本实现了E601型蒸发站在线监测。

Taking the Qunkule Hydrological Station in Chonghu'er Town,Burjin County,Altai Region,Xinjiang as an example,the comparison and analysis of the artificial observation values of evaporation at the station from July to October 2019 and those of the E601 evaporation station were carried out.The results show that the days with absolute errors of evapotranspiration observations within 0.5 mm and 0.2 mm at evaporator stations are 109 days and 84 days,accounting for 88.62%and 68.29%of the total observation days,which meets the requirements of the"Water Surface Evaporation Observation Specification".Moreover,the correlation analysis of the effective comparison data of manual observation and evaporation station observation shows that the daily evaporation value of manual observation and evaporation station observation has a good linear correlation,and the Qunkule Hydrological Station has basically realized the E601-type evaporation station online monitoring.
