中文摘要：

随着多波束测深技术的广泛应用以及人们对高精度海底地形测量的迫切需求,海洋测深已由离散、低精度、低效率向全覆盖、高精度、高效率的方向发展,传统的技术设计已不能满足对海底精细描述的要求。而测线布设作为海区技术设计的一个重要环节,其设计方法仍相对滞后。基于这一现状,在深入分析测线布设对测量成果的影响机制基础上,提出了一种全新的多波束测线布设优化方法,并详细给出流程图。整体研究结果表明：该优化方法是合理可行的,体现了逐步优化设计的思想,更符合实际测量需求。

英文摘要：

With wide application of multibeam echosounder systems and urgent need for high-precision bathymetric survey, traditional technical design is no longer able to meet the demand of accurate seafloor topographic survey. The development trends of marine bathymetry are featured by full coverage, high accuracy and high efficiency. As an important link in technical design, the survey line layout technique has not been fully developed in China. On the basis of analyzing the effect mechanism of survey line layout on surveying results, a newly optimized method of multibeam survey line layout is presented, with a detailed flow diagram given in this paper. The results from the overall research indicate the feasibility of this optimizing method, which embodies the gradual design idea, well suited to practical surveying requirements.
