【摘要】：南通近岸海域位于南黃海和東海的交界處,灘涂寬闊,由于同時(shí)受到東海的前進(jìn)潮波和黃海的旋轉(zhuǎn)潮波兩個(gè)不同性質(zhì)的潮波系統(tǒng)的影響,幾乎每年發(fā)生的”怪潮”災(zāi)害給南黃海沿海地區(qū)造成的經(jīng)濟(jì)損失與人員傷亡,已對(duì)沿海地區(qū)的經(jīng)濟(jì)建設(shè)與和諧社會(huì)建設(shè)構(gòu)成嚴(yán)重威脅。 因此,加強(qiáng)蘇北沿海地區(qū)海洋災(zāi)害監(jiān)測(cè),獲取海洋即時(shí)信息,研究預(yù)警技術(shù),研制防災(zāi)決策輔助系統(tǒng),發(fā)布準(zhǔn)確的”怪潮”激流災(zāi)情,是保障人民生命財(cái)產(chǎn)安全與社會(huì)穩(wěn)定的迫切需要。 本論文針對(duì)”怪潮”激流災(zāi)害災(zāi)情,根據(jù)現(xiàn)場(chǎng)調(diào)查數(shù)據(jù)和數(shù)值模式的計(jì)算結(jié)果,結(jié)合以往收集的空間數(shù)據(jù)模型資料以及地形資料數(shù)據(jù),確定激流”怪潮”的影響因子,建立激流“怪潮”的災(zāi)害評(píng)價(jià)模型,通過(guò)預(yù)報(bào)數(shù)值與地形數(shù)據(jù)的疊加分析、最短路徑優(yōu)化和動(dòng)態(tài)最短路徑優(yōu)化的方法,根據(jù)災(zāi)害指標(biāo)因子分析模型、模糊模式識(shí)別模型等理論知識(shí),建立”怪潮”易發(fā)區(qū)域?yàn)?zāi)害等級(jí)評(píng)價(jià)標(biāo)準(zhǔn)和災(zāi)害防御、人員撤離應(yīng)急方案,設(shè)計(jì)和實(shí)現(xiàn)”怪潮”災(zāi)害的應(yīng)急預(yù)警方案,使用空間數(shù)據(jù)分析、空間數(shù)據(jù)庫(kù)及空間地理信息系統(tǒng)的再現(xiàn)分析技術(shù)設(shè)計(jì)和實(shí)現(xiàn)了防御”怪潮”災(zāi)害輔助決策系統(tǒng)的研制。實(shí)際應(yīng)用表明系統(tǒng)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.
