摘要
为适应以自动化监测为主的“水文信息化”发展要求,黄家庄水文站引入HY.FFZ-3定量汲水水面蒸发自动测量系统,并与人工观测开展比测。根据该站2020年比测资料,采用差值、相关性分析方法,对人工和自动蒸发、降雨进行对比分析,结果显示:自动测量系统监测结果与人工观测值(降雨、蒸发)相关关系良好,蒸发差值主要集中在-0.5~0.5mm之间。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。
In order to meet the development requirements of hydrological informatization mainly based on automatic monitoring,the automatic measuring system of HY.FFZ-3 quantitative water surface evaporation is introduced in Huangjiazhuang Hydrological Station and compared with manual observation.According to the comparative data of the station in 2020,the manual and automatic evaporation and rainfall are compared and analyzed by difference and correlation analysis methods.The results show that the monitoring results of the automatic measuring system have a good correlation with the manual observation values(rainfall and evaporation).The evaporation difference is mainly concentrated in the range of-0.5~0.5mm.It shows that the system observation results are reliable and meet the accuracy requirements of the water surface evaporation observation specifications.
