全自动水面蒸发监测系统在官良水文站的应用分析

Application Analysis of Automatic Water Surface Evaporation Monitoring System in Guanlinang Hydrological Station

水面蒸发是水循环过程中的一个重要环节,是水文监测的重要要素。为了提高水文监测能力,官良水文站引进MKHY.FFZ-03型全自动水面蒸发监测系统,该系统采用主动定量汲水控制模式和先进的传感器测量技术,改变传统的溢流测量模式,能够解决溢流过程测量不准确的问题。根据官良水文站2020年10月至2021年3月的水面蒸发比测资料,对人工观测和自动监测的蒸发值进行日蒸发误差分析、旬蒸发误差分析、月蒸发误差分析。通过比测分析,全自动水面蒸发监测系统各项评定指标符合要求,能够替代传统的人工观测水面蒸发,提高了水文测验的工作效率,向智慧水文建设目标迈进一步。

Water surface evaporation is an important link in water cycle and an important element of hydrological monitoring.In order to improve hydrological monitoring capabilities,Guanliang Hydrological Station introduced the MKHY.FFZ-03 fully automatic water surface evaporation monitoring system,which adopts active quantitative water pumping control mode and advanced sensor measurement technology,changing the traditional overflow measurement mode,and can solve The problem of inaccurate measurement of the overflow process.According to the water surface evaporation comparison data of Guanliang Hydrological Station from October 2020 to March 2021,the daily evaporation error analysis,ten-day evaporation error analysis,and monthly evaporation error analysis are carried out on the evaporation values of manual observation and automatic monitoring.Through comparison and analysis,the evaluation indicators of the fully automatic water surface evaporation monitoring system meet the requirements,which can replace the traditional manual observation of water surface evaporation,improve the efficiency of hydrological testing,and take a step toward the goal of smart hydrological construction.
