摘要
水面蒸发观测是水文要素观测的重要组成部分,传统的器测法需要人工按时记录蒸发器内的水位变化、降水和溢流量,由此得到蒸发量。明光水文站引入FFZ-03型全自动数字水面蒸发器,设备采用了主动定量汲水的工作方式,提高测量准确性。根据该站一年的比测数据,采用误差分析方法,对人工观测数据与自动蒸发器观测得到的数据进行对比分析,结果显示,该数字化水面蒸发设备监测结果与人工观测值一致性关系良好,表明系统观测结果可靠,满足水面蒸发观测规范的精度要求。
Water surface evaporation observation is an important component of hydrological element observation.Traditional instrument measurement methods require manual recording of water level changes,precipitation,and overflow in the evaporator on time,in order to obtain evaporation.The Mingguang Hydrological Station has introduced the FFZ-03 fully automatic digital water surface evaporator,which adopts an active quantitative water suction working mode to improve measurement accuracy.Based on the one-year comparison data of the station,error analysis method was used to compare and analyze the evaporation data collected automatically by the evaporator with the manually observed data.The results show that the monitoring results of the digital water surface evaporation equipment have a good correlation with the manually observed values,indicating that the overall observation results are reliable and meet the accuracy requirements of the water surface evaporation observation specifications.
