中文摘要：根据2016年枯水季、丰水季和平水季海南岛近岸海域表层海水现场调查资料,对该海域表层海水中溶解无机磷(DIP)的时空分布特征进行研究,评价其污染水平和营养盐结构,分析该海域富营养化程度,并探讨了研究区域DIP的主要来源及与环境因子之间的关系.结果表明,海南岛近岸海域表层海水DIP的平均浓度为(0.008±0.006) mg/L,浓度范围为0.000~0.062mg/L,万宁小海海域是3个水季的主要污染区域;平水季研究海域DIP污染水平高于枯水季与丰水季;富营养化指数变化范围为0.00~3.94,平均为(0.21±0.46),总体上海南岛近岸表层海水富营养化程度较低,但局部海域富营养化问题依然突出.

外文摘要：Based on the field investigation data of surface seawater along the Hainan Island coastal water in dry, wet and normal flow seasons of 2016 year, the spatiotemporal distribution characteristics of dissolved inorganic phosphorus(DIP) were studied. The DIP pollution level, nutrient composition and eutrophication were evaluated. Meanwhile, the main source of DIP and the relationship between DIP and environmental factors were also discussed. The results showed that the average concentration of DIP was(0.008±0.006) mg/L, ranged from 0.000 mg/L to 0.062 mg/L in the surface seawater along the Hainian Island coastal area. The high concentration of DIP was distributed around the Xiaohai adjacent coastal water of Wanning city in all seasons. The pollution level of DIP in normal flow season was higher than that in wet and dry flow seasons. The eutrophication index ranged between 0.00 and 3.94, with an average value(0.21±0.46). The overall eutrophication of Hainan Island adjacent seawater was relatively low, but the eutrophication problem in some local coastal water areas was still outstanding.
