【摘要】：有效选择重点监控区并对其进行长期监测是赤潮预警系统建立的关键。本文研究海南岛近岸海域赤潮发生历史记录,分析不同区域赤潮发生频次、规模、危害程度及原因种毒性,提取赤潮发生的综合信息,评价区域赤潮的严重程度;同时分析近岸海域的营养盐状况及水体的扩散能力,评价水体的富营养程度;利用GIS手段,判断海南岛近岸海域赤潮易发程度,即识别赤潮高发区、赤潮易发区及潜在赤潮发生区。再结合近岸海域环境功能区划,有效划定了赤潮重点监控区,赤潮防控区及赤潮预警区。进一步结合现场大面调查数据对重点监控区进行分级,提高了赤潮的有效监控和预警。
[Abstract]:The key to the establishment of red tide early warning system is to select the key monitoring area effectively and to monitor it for a long time. This paper studies the historical records of red tide occurrence in the coastal waters of Hainan Island, analyzes the frequency, scale, harm degree and toxicity of red tide in different regions, extracts the comprehensive information of red tide occurrence, and evaluates the severity of red tide in different regions. At the same time, the nutrient status and the diffusion capacity of the water were analyzed, and the eutrophication degree of the water was evaluated. The GIS method is used to determine the degree of red tide in the coastal waters of Hainan Island, that is, to identify the high incidence area of red tide, the area prone to the occurrence of red tide and the potential red tide area. Combined with the environmental function zoning of the coastal sea area, the red tide monitoring area, the red tide prevention and control area and the red tide warning area are effectively delineated. In order to improve the effective monitoring and early warning of red tide, the paper classifies the key monitoring area based on the field survey data.
