本文通过表层水温日变化、误差对比、数字特征值对比以及相关关系对比的统计分析,认为目前所用的传统的海滨浅水区表层水温观测一天采用三次定时观测时次以及02时记录用08时代替的统计方法很有改进的必要,建议有条件的站增加02时观测,对于无条件进行02时观测的站,02时记录应改目前的代替法为内插法,以尽可能降低因时次不足带来的误差,使得资料更趋于合理、准确和具有代表性。 Based on the statistical analysis of diurnal variation of surface water temperature, contrast of errors, comparison of digital eigenvalues ​​and comparison of correlations, the paper considers that the surface water temperature of the traditional coastal shallow water area is observed by using three times of regular observation and 02 hours of time Statistics method is very necessary for improvement, it is recommended to increase the observation station 02 when the conditions for the observation of the station 02 unconditional, 02 records should be replaced by the former method of substitution for interpolation, in order to minimize due to insufficient time zone To the error, making the data more reasonable, accurate and representative.
