摘　　要：《海道测量标准(S-44)》作为全球海道测量的基础标准,对全球海道测量技术的发展与进步具有重要的指导意义。为促进第6版标准的学习研究及推广应用,着眼于“航行安全测量最低水深标准”内容,就测量等级分类、水深测量不确定度、特征物探测及水深探测覆盖率4个方面内容进行了分析研究,研究表明新版标准在等级分类、水深探测覆盖率方面相关规定更为全面灵活,为我国制定和更新海道测量国家标准提供了重要的基础文件和参考依据。As the basic standard of global hydrographic survey,S⁃44 is of great guiding significance to the development and progress of global hydrographic technology.In order to promote the study and application of the 6th edition standard,this paper focuses on the content of“Minimum water depth standard for navigation Safety Measurement”,and analyzes and studies the survey classification,uncertainty,features detection and bathymetric coverage.The study shows that the new standard is more comprehensive and flexible in terms of classification and bathymetric coverage,which provides an important basic document and reference basis for China to formulate and update the national standard of hydrographic survey.
