摘　　要：在海道测量中,由于无法对测量数据进行多余和重复观测,因而不能精确测定各种误差,同时也几乎没有测量成果质量的控制指标,这正是多波束测深数据质量评估所面临的现实且急需解决的难题。基于国际海道测量规范S-44(5th)的要求,研究了不确定度在多波束数测深数据质量评估中的应用。通过实例分析可知,测量结果的可用性在很大程度上取决于其不确定度的大小,不确定度越小,说明测量结果质量越高,越具有可靠性。因此,将不确定度充分合理地应用于多波束测深数据处理和评估是一种最为理想的途径。In the hydrographic survey,due to the fact that measurement data can not be observed redundantly and repeatedly,the errors can not be measured accurately,at the same time,there are almost no control indexes of the measurement result quality,and this is the reality problem faced in the multibeam sounding data quality assessment which is needed to be resolved.On the basis of the IHO Standards for Hydrographic （S-44）,the paper studies the uncertainty in the application of multibeam sounding data quality assessment.According to the instance analysis,we can know that the availability of the measurement result mainly depends on the uncertainty,and the smaller is the uncertainty,the higher is the measurement result and the better is the reliability.Therefore,it will be an ideal way to reasonably apply uncertainty to multibeam sounding data processing and assessment.
