秦皇岛海域赤潮灾害损失评估系统设计与实现

本文根据已存在的赤潮灾害损失评估技术方法，并针对秦皇岛海域海水养殖业与滨海旅游业等的实际情况，依据业务工作的具体需求以及能够得到的评价数据，并结合地理信息系统技术建立了基于Visual C#和ArcGIS Engine组件的秦皇岛海域赤潮灾害损失评估系统。系统实现了数据输入与管理、GIS数据检测查询、损失评估模型计算、结果制作与输出的功能，并将赤潮灾害损失评估结果以直观、可视化的形式进行表达。评估结果包括海水养殖业损失评估、滨海旅游业损失评估、赤潮灾害应急监测费用损失评估以及处置费用损失评估，并对当地的灾后救援以及经济损失评估起到重要作用，同时也为管理者的相关决策提供科学依据。

Design and implementation of losses assessment system for red tide disasters in Qinhuangdao sea area

Based on the existing losses assessment methods for red tide disasters proposed by the predecessors and the hazard characteristics of red tide disasters, economic loss assessment index of red tide disasters is put forward based on the actual needs and the operational data that can be got in the operational work.The losses assessment system for red tide disasters is based on ArcGIS Engine and Visual C#, established to realize functions of data input and management, GIS data detection query, loss evaluation model calculation, thematic maps production and output, and achieve visualization of assessment results.The results of the assessment include the losses assessment of marine aquaculture industry, the losses assessment of coastal tourism, the assessment of the cost of emergency monitoring and the assessment of the cost of disposal of red tides.It also plays an important role in the local post-disaster rescue and economic losses assessment and also provides the scientific basis for the managers' decision-making.
