Choosing the surface salinity from SODA database during 1981 to 2010, the climatic distribution characteristics of surface salinity at the continental shelf of the East China Sea for the new 30-year climate reference period (1981-2010) were analyzed, to lay the foundation for further study of climate change. The results showed that: (1) The average salinity of the surface layer in the study area increased gradually from the Yangtze River estuary to the southeast. The isoline has a circular distribution near the Yangtze River estuary, and it is generally northeast-southwest in other sea areas of the study area; (2) In the inter-monthly change, the highest salinity in March is 27.38psu; the 5-8 month is the low salinity season, and the lowest salinity in August is 22.30psu; September-December is the season of salinity rise; (3)The annual amplitude of salinity has two regional changes: the largest positive center is located in the northeast of the Yangtze River estuary, the largest negative center is located in the waters near Hangzhou Bay south of the Yangtze River estuary.
