自动蒸发水面高度测量检查和评定方法探讨

蒸发是自然界水量平衡三大要素之一，水面蒸发是水文监测的重要项目。随着科学技术的快速发展，现代化技术在水文监测领域得到广泛应用，水面蒸发监测由传统的人工观测方式逐渐被自动监测所取代，但现行的《水面蒸发观测规范》（SL630-2013）等相关规范规程对水面蒸发自动监测技术中蒸发器水面高度测量精度野外检查和评定方法尚无明确规定。为了探索水面自动蒸发系统野外检查方法，以高沙水文站为例，采用人工取水模拟水面蒸发的方式进行了试验研究，并进行人工和自动观测蒸发数据对比分析。经试验研究，该站水面蒸发自动监测系统的水面高度测量精度满足规范要求，检查和评定方法可为其他类似水面蒸发自动监测仪器设备水面高度测量安装调试提供参考，为今后水面蒸发观测规程规范修编提供了依据。

英文摘要:

Evaporation is one of the three elements of the natural water balance and water surface evaporation is an important project of hydrologic monitoring.With the rapid development of science and technology,modernization has been widely used in hydrologic monitoring and the traditional manual methods of monitoring of water surface evaporation are gradually being replaced by automatic monitoring.However,it is not clearly defined about the standard for observations of Water Surface Evaporation Code（SL630-2013）and other related specifications on the evaporator surface height measurement accuracy of field testing method in automatic monitoring technology of water surface evaporation.In order to explore the precision test method of water surface automatic evaporation system,taking Gaosha hydrological station as an example,an experimental study was carried out by simulating evaporation of water surface with artificial water intake and a comparative analysis of evaporation data between artificial and automatic observation was made.The results show that the surface height measurement accuracy of field testing method is in accordance with the requirements.The testing and evaluation method can provide a reference for other similar surface height measurement accuracy of testing method in automatic monitoring technology of water surface evaporation as well as a scientific foundation for the revision of the observation of water surface evaporation specification of order.
