摘　　要：高精度高分辨率全球海底地形模型是研究地球形状及内部结构的重要基础数据,在海底板块运动研究、海啸监测预警、深海资源勘探、海底工程建设、航海安全保障和海洋国土划界等方面具有重要价值。广袤而深邃的海洋使得人类精准测绘海底地形面临艰巨挑战,由于卫星测高技术具备全球覆盖、高精度高分辨率和周期性重访海洋动态观测能力,已成为全球海底地形测绘的主要手段。本文概述了利用卫星测高数据反演全球海底地形的研究现状与最新进展,研究内容主要包括卫星测高数据反演海底地形的基本原理、主要卫星测高模式与任务、海洋重力场反演、海底地形反演方法及模型产品等。最后,展望了构建高精度动态全球海底地形模型的发展趋势,并从卫星测高数据、船测水深数据和海底地形反演技术等方面开展了可行性分析。High-precision,high-resolution global seafloor topography models are critical foundational datasets for studying the Earth’s shape and interior structure.They are significant in multiple domains,including seafloor plate movement research,early tsunami monitoring,deep-sea resource exploration,underwater marine construction projects,ensuring maritime safety,and delineating marine territorial boundaries.The extensive and profound realms of the oceans present a formidable challenge for meticulously mapping the seafloor topography.However,satellite altimetry,with its global coverage,high precision,high resolution,and the ability to conduct regular observations of ocean dynamics,has emerged as the primary method for obtaining global bathymetric data.This paper provides an overview of the current state and recent developments in recovering bathymetry from satellite altimetry-derived data.It encompasses fundamental principles,major modes,and missions in satellite altimetry,marine gravity field inversion,methods for seafloor topography inversion,and seafloor topography model products.Additionally,the paper provides insights into the trends and prospects for constructing high-precision,dynamic global seafloor topography models.
