摘　　要：选取我国沿岸18个海洋观测站,对SBF3-1、SBF3-2、LPB1-2、SZF型自动测波仪器与目测、岸用测波仪两种非自动测波方式的海浪观测参数进行了比较分析。研究发现,与非自动测波方式相比,SBF3-1型浮标观测波高无明显变化,观测周期具有显著变大的特点;SBF3-2型浮标观测波高多数情况下具有变小的特点,观测周期保持不变或趋于变大;LPB1-2型声学测波仪观测波高有微弱变大的特点,观测周期无明显变化或微弱变大;SZF型浮标观测波高和观测周期既存在明显变大的情况,也存在明显变小或变化不明显的情况,无明显共性观测特点。By selecting 18 marine stations in offshore of China,intercomparison of wave data measured from visual instruments and automatic instruments were carried out.Compared with visual measurements,the mean wave heights of SBF3-1 are always similar with visual measuring wave heights.Nevertheless,the wave periods of SBF3-1 are always larger than visual measurements.In most cases,the mean wave heights of SBF3-2 are smaller than visual measurements,the wave periods of which are not less than visual measurements.The mean wave heights of LPB1-2 are slightly larger than visual measurements,the mean wave periods of which are consistent with visual measurements.There are no obvious common features for SZF.
