嵊山-枸杞附近海域盐度监测管理数据

嵊山-枸杞拥有全国最大的贻贝养殖基地，通过监测嵊山-枸杞附近海域各观测点数据，了解海洋中的盐度变化趋势和异常情况，并对海洋生态环境进行监测和评价，为嵊泗贻贝养殖及海洋大数据服务平台等提供数据支持。通过计算嵊山-枸杞附近海域历年盐度平均数值，作为海域盐度历史基准数据，将当月该海域平均的盐度数值与盐度基准数据作比（海域当月平均盐度数值/海域盐度历史基准数据），得到该月该海域的盐度指数，如盐度指数在0.9-1.1的，则定义为“正常”，盐度指数在1.1-1.2或0.8-0.9的，则定义为“预警”，盐度指数在0.8以下或者1.2以上的，则定义为“异常”。

Shengshan-Gouqi hosts the largest mussel farming base in China. This dataset collects data from multiple observation stations in the sea area adjacent to Shengshan-Gouqi, to track marine salinity change trends and anomalous conditions, monitor and evaluate the marine ecological environment, and provide data support for services including the Shengsi mussel farming industry and marine big data service platform. Specifically, the multi-year average salinity values of the adjacent sea area are first calculated as the historical salinity baseline data of the region. Then, the monthly salinity index of the sea area is obtained by dividing the current month's average salinity value by the historical baseline data, i.e., (monthly average salinity value / historical salinity baseline data). The salinity index is classified as follows: "Normal" when the index falls within the range of 0.9 to 1.1; "Alert" when the index ranges from 1.1 to 1.2 or 0.8 to 0.9; and "Abnormal" when the index is below 0.8 or above 1.2.
