基于在线监测浮标的银滩海域水质要素趋势分析

基于布设在北海银滩海域的GX-17号在线监测浮标2019年实施监测的各要素实时数据,分析了银滩海域水质要素变化趋势,探讨了浮标在海洋旅游区环境保护中的应用。监测结果表明,银滩海域海水水温在6-9月维持在30℃左右的较高温度,6-9月pH、溶解氧、盐度均比其它时段较低,pH、溶解氧、盐度与水温相关性较为显著;溶解氧最高值出现在8月,可能受到短时间藻类增殖的影响;无机氮和活性磷酸盐的含量在3月至5月较高,应受夏季降雨和地表径流输入影响较大。

Based on the real-time data in 2019of the monitoring elements of gx-17 online monitoring buoy deployed in the Yintan sea area of Beihai,the change trend of water quality elements in Yintan sea area is analyzed,and the application of buoy in environmental protection of marine tourism area is discussed.The monitoring results show that the sea water temperature in the Yintan sea area is maintained at a high temperature of about 30℃from June to September.The pH,DO and salinity are lower than those in other periods from June to September,and the correlation between pH,DO,salinity and water temperature is significant;the highest value of DO appears in August,which may be affected by algae proliferation in a short time;the contents of inorganic nitrogen and active phosphate are higher from March to May In summer,rainfall and surface runoff input have great influence..
