舟山六横岛附近海域盐度监测管理数据

六横岛拥有大量的水产养殖基地，通过监测六横岛及其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，为六横岛海水养殖、海洋工程建设等工作提供数据支撑。通过计算六横岛附近海域历年平均数值，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”。

Liuheng Island boasts numerous aquaculture bases. This dataset monitors data from various observation stations in and around the waters of Liuheng Island, to grasp salinity variation trends and abnormal conditions in the ocean, as well as to monitor and evaluate the marine ecological environment, thereby providing data support for marine aquaculture, offshore engineering construction and other related work in Liuheng Island. By calculating the multi-year average values of the adjacent sea area of Liuheng Island as the historical salinity baseline data of the sea area, the salinity index for the current month in this sea area is obtained by comparing the monthly average salinity value with the historical salinity baseline, i.e., (monthly average salinity value / historical salinity baseline). Specifically, a salinity index between 0.9 and 1.1 is defined as "Normal"; a salinity index between 1.1 and 1.2 or 0.8 and 0.9 is defined as "Alert"; and a salinity index below 0.8 or above 1.2 is defined as "Abnormal".
