摘　　要：针对"武汉国际长江抢渡挑战赛"中将近三分之二的选手不能成功到达终点这一突出问题,建立了不同斜率赛场条件下时间最优的长江竞渡模型。结合其影响因素,讨论了不同情况下参赛选手所应采取的优化策略,并在MATLAB/simulink仿真平台上运用迭代搜索法求解该实际问题,仿真结果显示了各年竞渡的最优成绩,证明了研究不同赛场条件下长江竞渡优化策略的重要性。该模型简单、容易理解和运用,在实际竞渡、洋流影响的航行及气流影响的飞行领域都具有参考应用价值。In view of the problem that nearly two thirds players cannot successfully reach the object in ＂The Wuhan International Yangtze River Crossing Challenge＂,the paper establishes a model of swimming race across the Yangtze River according to different athletic field conditions.It also discusses the optimized strategy that the swimming race contestant should adopt under different athletic field condition.It solves the actual problem using the iterative search method on the platform of MATLAB/simulink.The simulation results show the best results of each year which prove the importance of this study.The model is simple and easy to be understood and has reference value in the actual swimming race.
