摘要:
长期以来,鄱阳湖水温测验工作一直采取人工观测方式,这种方式易于保证测验质量,但工作量大,且效率低下。本文以鄱阳湖星子水文站为例,基于自记水温计与人工观测水温的同步观测资料,探讨两者之间的关系,并建立几种水温关系模型,分析比较各模型优缺点,分析误差产生的原因。结果表明:混合模型法精度最高,模拟值与真值误差在0.4℃以内,自记水温计观测数据经过换算后,可以用于湖区水温资料的整编。表明自记水温计可为水文巡测工作提供有效的支持,并在水文巡测中起到一定的作用。

Abstract: Human observation of water temperature can ensure the quality of data, but the work is in effective. Based on synchronous temperature data from the recording temperature and human observations, this paper analyses their relationship and establishes relationship models. The strength and weakness of these models are discussed. Test results show that the hybrid model has the highest precision and the simulation values are consistent with the true values. The maximum absolute error is less than 0.4˚C. Recording temperature data after conversion can be used in Poyang Lake water temperature data base. It is suggested that recording thermometer can provide effective support of hydrological survey work.
