摘　　要：会聚区调查是海洋声传播损失调查的一项重要内容,在调查前大致了解海区中的会聚区分布情况,将给会聚区调查带来极大的便利。针对深海会聚区调查,提出了一种利用射线声学法对会聚区进行预估,从而大大提高了工作效率,降低了调查成本,保证了调查数据的质量。Convergence zone survey is an important part of marine acoustic propagation loss survey. If the distribution of convergence zone in the sea area is known roughly in advance, it will be very helpful for convergence zone survey. A method basing on ray acoustics to predict the distribution of convergence zone is given, which could increase efficiency greatly ,reduce survey cost and guarantee the quality of survey data.
