分析了国内外各种自然灾害评估系统的研究现状以及赤潮灾害风险评估的研究成果,赤潮灾害风险评估的指标体系、评估模型已经初步建立,并获得了较好的可行性和正确性,建成了赤潮管理信息系统。在此基础上提出了建立赤潮灾害风险评估系统的初步设想。系统建成后,基于GIS的空间分析功能,结合赤潮灾害风险评估数据库,可以快速、实用、准确地提供专门的赤潮灾害风险成果,为有关部门的灾害预测预报以及选取有效而科学的防灾、减灾和救灾措施提供依据。
The research status of various natural disaster assessment systems at home and abroad, the research results of the risk assessment of red tide disasters, and the index system of the assessment of the risk of red tide disasters are analyzed. The assessment model has been initially established and has obtained good feasibility and correctness. Red Tide Management Information System. Based on this, a tentative idea of establishing a risk assessment system for red tide hazard is proposed. After the completion of the system, the spatial analysis function based on GIS, combined with the database of red tide hazard risk assessment, can provide special results of red tide disaster risk quickly, practically and accurately, and provide effective and scientific disaster prevention and forecast for relevant departments and selection of effective disaster prevention and mitigation And disaster relief measures to provide the basis.
