摘　　要：为满足水文观测的自动化要求,给水文站自动蒸发设备的推广使用提供依据,在安塞水文站安装FFH100型自动蒸发设备,统计自动蒸发设备累积观测的与人工观测的日蒸发量数据(共计82组),在分析自动蒸发设备构造及计算原理的基础上,对82组日蒸发量数据进行比对分析,分析观测误差及来源。通过数据定量回归分析及自动蒸发设备实际使用,结果表明:人工和自动蒸发设备观测得到的2个数据变量的相关系数R达到0.988,具备很高的单值对应关系,能够满足水面蒸发观测规范要求,且自动蒸发设备在降雨期间能对蒸发量进行计量并实现自动采集与远程发报,实现蒸发观测的自动无人化,可作为北方地区非冰期水面蒸发自动测量设备选择之一。In order to meet the requirements of automatic hydrological observation and to provide reference for the promotion of automatic evaporation equipment at the hydrological station,FFH100 automatic evaporation equipment has been installed at Ansai Hydrological Station to record daily evaporation data(82 groups in total) from automatic evaporation equipment and manual observation respectively. 82 groups of daily evaporation data are compared to analyze the observation error and source. The results of quantitative regression analysis of data and the use of automatic evaporation equipment show that the correlation coefficient of the two variables observed by manual and automatic evaporation equipment reaches 0.988,which has a high single value correspondence and can meet the requirements of surface water evaporation observation specifications. In addition,the automatic evaporation equipment has the functions of automatic collection and remote reporting,which can realize the automation of evaporation observation,and can keep measuring evaporation during rainfall. It can be used as one option of automatic measurement equipment for surface water evaporation during non-glacial periods in Northern China.
