摘要：
利用Morlet小波变换方法，对连云港海域1965—1994年的海水盐度时间序列变化的周期特征进行了综合分析。结果表明，这30年连云港的盐度变化具有14年和5年左右的周期变化，多年均值为29.39，盐度变化的阶段性特征明显。
关键词: 盐度, 小波变换, 周期
Abstract:
We employ Morlet wavelet transform to analyze the periodical characteristic of salinity change in Lianyungang coastal sea area from 1965 to 1994, Results indicate that salinity change in Lianyungang coastal sea area has periods of 14 years and 5 years for the past 30 years. Salinity mean value is 29.39. It is obvious for the periodic characteristics of salinity change.
Key words: salinity, wavelet transform, periodicity
