| Abstract: | In order to understand the water quality of the artificial reef area,the seawater environmental conditions of the Xiangyun Bay Marine Ranch was investigated from 2019 to 2020.The results showed that the salinity of the seawater did not change much,with an average of 30.91‰,and the transparency of the reef area was lower than the control area.The dissolved oxygen content was the highest in September,with a range of 8.10~8.81 mg/L.The COD content was the highest in March and the lowest in September,and the concentration range was 0.83~1.48 mg/L.The range of active phosphate content was 0.01~0.02 mg/L,and the DIN content in the reef area was higher than that in the control area.The marine environment is at a potential eutrophication level with moderate phosphorus restriction. |
