摘　　要：随着海上化学品运输、转存量的不断增加,化学品泄漏风险也日益增加,对海上泄漏化学品行为进行合理、可信的数值模拟并将其结果直观地显示是目前应急辅助决策和风险评估的关键技术。通过对风场和潮流场的数值模拟,并运用Monte-Carlo法对海气相互作用的研究,确立海洋-大气耦合模型全方位的模拟泄漏化学品在海洋和大气中的行为动态,与GIS集成,形成一个整体。实现对泄漏化学品灾害影响模拟的准确性和直观性。同时提出海上泄漏化学品灾害影响模拟的总体结构和技术路线,阐述其实现的基本原理,构建宁波市海上泄漏化学品灾害影响模拟的初步框架。With the increasing transportation of chemicals in bulk by ships, the risk of the chemicals spill is getting higher and higher. So the reasonable numerical modeling of the spilled chemicals at sea is a key technique for the risk assessment and contingency decision-making. The paper develops the tidal current and the wind＇s numerical simulation, using Monte-Carlo to study the water-air interactive model, so the fate and behaviors of the spilled chemicals at the sea and in the air can be simulated simultaneous, then in- tegrated with GIS, forming an integrated image. Thus achieving the leakage of chemical disasters affects the accuracy of simulation and visualization. Simultaneously the paper puts forward leakage of chemicals on the sea disasters simulation＇s technology route and the overall structure, expresses the basic principles and constructs the preliminary frame of Ningbo ocean leaking speeialty chemicals scourge influence simulation.
