海洋工程对觉华岛国家级海洋公园海域生态环境影响研究

文章根据2016—2019年觉华岛周边海域生态环境监测结果,并结合期间大规模海洋开发活动,分析了觉华岛国家级海洋公园海域环境变化趋势。结果表明:2016—2019年,觉华岛周边海域水质要素监测结果均符合《海水水质标准》中的二类标准,沉积物要素监测结果均符合《海洋沉积物质量》中的一类标准。水质与沉积物大部分监测要素的平均含量年际变化呈先降低再上升的变化趋势,生物环境状况整体水平变化情况与水质和沉积物的变化趋势有良好的对应关系,说明海洋工程建设对觉华岛国家级海洋公园海域生态环境造成了一定的负面影响,但影响程度不大。

Study on the Influence of Ocean Engineering on the Marine Ecological Environment of Juehuadao Island National Marine Park

Based on the monitoring results of ecological environment in the sea area around Juehuadao island in 2016—2019,combined with the large-scale marine development activities during the period,the paper analyzed the changing trend of marine environment in sea area of Juehuadao Island National Marine Park.The results showed that the water quality of the investigated areas reached the second-class water quality according as The Chinese National Standard of Seawater Quality in 2016—2019,and the sedimentary quality of the investigated areas reached the firstclass sedimental quality according as The Chinese National Standard of Sediment Quality.The average content of most monitoring elements of water quality and sediment decreased first and then increased,and the overall level of biological environment had a good corresponding relation with the change trend of water quality and sediment,which indicated that the marine engineering construction has a certain negative impact on the marine ecological environment of Juehuadao Island National Marine Park,but the impact was not significant.
