舟山六横岛附近海域无机磷监测管理数据

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，了解海洋中的无机磷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来测得的无机磷的平均数值，，作为海域无机磷历史基准数据，将当月该海域平均的无机磷数值与无机磷基准数据作比（海域当月平均无机磷数值/海域无机磷历史基准数据），得到该月该海域的无机磷指数，如无机磷指数在0.9-1.1的，则定义为“正常”，无机磷指数在1.1-1.2或0.8-0.9的，则定义为“预警”，无机磷指数在0.8以下或者1.2以上的，则定义为“异常”。

Liuheng Island boasts a large number of aquaculture bases. This dataset collects data from various monitoring stations on Liuheng Island and its adjacent sea areas to analyze the changing trends and anomalies of inorganic phosphorus in the ocean, as well as to monitor and evaluate the marine ecological environment. The dataset provides data support for mariculture, marine engineering construction and other related sea-use projects on Liuheng Island. Specifically, the average inorganic phosphorus concentration measured in the waters near Liuheng Island over the years is calculated as the historical baseline data for inorganic phosphorus in the waters. The inorganic phosphorus index for the current month is derived by dividing the monthly average inorganic phosphorus concentration in the waters by the historical baseline data, i.e., (monthly average inorganic phosphorus concentration of the current month in the waters / historical baseline inorganic phosphorus concentration of the waters). The index is categorized as follows: "normal" when the value ranges from 0.9 to 1.1; "early warning" when the value ranges from 1.1 to 1.2 or 0.8 to 0.9; and "abnormal" when the value is below 0.8 or above 1.2.
