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。
        Key areas identification,zone division and long-term monitoring is the key for establishing of harmful algae blooms( HABs) early warning system. Based on the historical records of HABs in the coastal waters of Hainan Island,severities of HABs events were evaluated by analyzing the comprehensive information of occurrence frequency,scale,damage degree and toxicity of causative species in different areas. Combining the diffusing capacity and nutrient availability with the severities degrees of historical records,high incidence region,prone region and potential region of HABs were identified in the coastal waters of Hainan Island by using GIS tools. Based on susceptible grades,environmental function zoning of coastal water and field data,the key monitoring regions were determined and graded.
