【摘要】：南通近岸海域位于南黄海和东海的交界处,滩涂宽阔,由于同时受到东海的前进潮波和黄海的旋转潮波两个不同性质的潮波系统的影响,几乎每年发生的”怪潮”灾害给南黄海沿海地区造成的经济损失与人员伤亡,已对沿海地区的经济建设与和谐社会建设构成严重威胁。 因此,加强苏北沿海地区海洋灾害监测,获取海洋即时信息,研究预警技术,研制防灾决策辅助系统,发布准确的”怪潮”激流灾情,是保障人民生命财产安全与社会稳定的迫切需要。 本论文针对”怪潮”激流灾害灾情,根据现场调查数据和数值模式的计算结果,结合以往收集的空间数据模型资料以及地形资料数据,确定激流”怪潮”的影响因子,建立激流“怪潮”的灾害评价模型,通过预报数值与地形数据的叠加分析、最短路径优化和动态最短路径优化的方法,根据灾害指标因子分析模型、模糊模式识别模型等理论知识,建立”怪潮”易发区域灾害等级评价标准和灾害防御、人员撤离应急方案,设计和实现”怪潮”灾害的应急预警方案,使用空间数据分析、空间数据库及空间地理信息系统的再现分析技术设计和实现了防御”怪潮”灾害辅助决策系统的研制。实际应用表明系统是有效的,合理的。
[Abstract]:The Nantong coastal waters are located at the junction of South Huang Hai and the East China Sea, and the tidal flat is wide. At the same time, because of the influence of two different nature tidal wave systems, the advancing tidal wave in the East China Sea and the swirling tidal wave in Huang Hai, The economic loss and casualties caused by the "strange tide" disaster that occurs almost every year in the coastal areas of southern Huang Hai have posed a serious threat to the economic construction and harmonious society construction in the coastal areas. Therefore, it is necessary to strengthen the monitoring of marine disasters in the coastal areas of northern Jiangsu, to obtain immediate marine information, to study the early warning technology, to develop a disaster prevention and decision support system, and to issue an accurate "strange tide" torrent disaster situation. It is the urgent need to ensure the safety of people's life and property and social stability. In this paper, according to the disaster situation of "strange tide" torrent, according to the field investigation data and the calculation result of numerical model, combined with the data of spatial data model and topographic data collected in the past, the influence factors of "strange tide" are determined. The disaster evaluation model of "strange tide" is established. Through the superposition analysis of forecast numerical value and topographic data, the method of shortest path optimization and dynamic shortest path optimization, according to the disaster index factor analysis model, Fuzzy pattern recognition model and other theoretical knowledge, the establishment of "strange tide" prone area disaster grade evaluation criteria and disaster prevention, personnel evacuation emergency plan, design and implementation of "strange tide" disaster emergency warning plan, using spatial data analysis, The reappearance and analysis technology of spatial database and spatial geographic information system (SGIS) has been designed and realized to develop the auxiliary decision system for defending "strange tide" disaster. Practical application shows that the system is effective and reasonable.
