舟山六横岛附近海域溶解氧监测管理数据

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，了解海洋中的溶解氧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，并为相关用海项目提供数据支撑。通过计算六横附近海域历年平均数值，作为海域溶解氧历史基准数据，将当月该海域平均的溶解氧数值与溶解氧基准数据作比（海域当月平均溶解氧数值/海域溶解氧历史基准数据），得到该月该海域的溶解氧指数，如溶解氧指数在0.9-1.1的，则定义为“正常”，溶解氧指数在1.1-1.2或0.8-0.9的，则定义为“预警”，溶解氧指数在0.8以下或者1.2以上的，则定义为“异常”。

Liuheng Island has numerous aquaculture bases. By monitoring data from various observation points on and around Liuheng Island and its adjacent sea areas, this dataset is established to understand the changing trends and abnormal occurrences of dissolved oxygen in the marine environment, monitor and evaluate the marine ecological environment, and provide data support for mariculture, marine engineering construction and other related sea utilization projects on Liuheng Island. Specifically, multi-year average values of the adjacent sea areas are calculated as the historical baseline data for dissolved oxygen. The dissolved oxygen index for a certain month is obtained by dividing the monthly average dissolved oxygen concentration of the sea area by its historical baseline dissolved oxygen data. The index is classified as follows: "Normal" when the value ranges from 0.9 to 1.1; "Alert" when the value is between 1.1–1.2 or 0.8–0.9; and "Abnormal" when the value is below 0.8 or above 1.2.
