舟山六横岛附近海域无机氮监测数据

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，了解海洋中的无机氮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。通过计算六横岛附近海域历年平均数值，作为海域无机氮历史基准数据，将当月该海域平均的无机氮数值与无机氮基准数据作比（海域当月平均无机氮数值/海域无机氮历史基准数据），得到该月该海域的无机氮指数，如无机氮指数在0.9-1.1的，则定义为“正常”，无机氮指数在1.1-1.2或0.8-0.9的，则定义为“预警”，无机氮指数在0.8以下或者1.2以上的，则定义为“异常”。

Liuheng Island hosts a large number of aquaculture bases. This dataset collects data from various observation points on and near the waters surrounding Liuheng Island, to identify the changing trends and abnormal conditions of inorganic nitrogen in the marine environment, as well as to monitor and evaluate the marine ecological environment. It provides data support for marine aquaculture, marine engineering construction and other relevant sea-use projects on Liuheng Island. The multi-year average values of the adjacent waters are calculated as the historical baseline data for inorganic nitrogen in the local waters. The inorganic nitrogen index for a specific month is obtained by dividing the monthly average inorganic nitrogen concentration of that month by the historical baseline inorganic nitrogen concentration of the waters, i.e., (monthly average inorganic nitrogen concentration / historical baseline inorganic nitrogen concentration). The index is classified into three levels: "Normal" if the index falls within 0.9–1.1; "Early Warning" if the index ranges from 0.8–0.9 or 1.1–1.2; and "Abnormal" if the index is below 0.8 or above 1.2.
