摘　　要：重磁测量在海岛礁及其邻域的应用与研究中不可或缺。由于海岛礁及邻域重磁场空间分布的梯度和幅度变化较大,又受地理环境与技术的限制,获取该区域高分辨率、高精度的重磁测量信息较为困难,导致测量成果质量不高且产品单一,亟需科技创新来扭转此局面。本文系统分析了海岛礁及其邻域地理环境、重磁特征和相关测量技术方法的发展现状,针对存在的问题,深入探讨了该领域的新技术、新方法及应用研究,并对未来发展方向作出展望:(1)加强重磁测量技术方法的研究,构建高水平的立体观测系统;(2)深化多源数据融合处理技术方法研究,丰富测量成果的输出方式;(3)充分利用海岛礁作为定点的中长期观测平台的天然优势,开展地球物理场的融合研究,拓展其应用与研究领域。Gravity and geomagnetic measurements play an indispensable role in the research of islands and reefs and their surrounding areas.Due to the large gradient and amplitude variations in the spatial distribution of gravity and geomagnetic fields,as well as the complex geographical environment in the islands and reefs and their surrounding areas,it is difficult to obtain highresolution and high-precision gravity and geomagnetic measurement information in this area with traditional gravity and geomagnetic measurement technologies and methods.This has led to a prominent problem of low-quality and limited-variety gravity and geomagnetic measurements results.Therefore,in response of national demands and based on the current development status of gravity and geomagnetic surveying and platform technologies in China,it is necessary to resolve this situation through scientific and theoretical innovations and the application of interdisciplinary and multi-technology integrated research tools.The following are some prospects for future development.Research on gravity and geomagnetic measurement technologies should be strengthened to provide technical support for high-performance scientific payloads on various detection platforms in the space,air,sea,and underwater domains.Furthermore,researchers should continuously improve the spatial resolution and accuracy of survey data,eliminate the gravity and geomagnetic measurement blind spots in marine areas,and enrich the scientific attributes of gravity and geomagnetic measurement information,thereby building a high-level,three-dimensional observation system.Research on multi-source data fusion processing technologies should be enhanced to improve the accuracy of data processing.Furthermore,the local gravity and geomagnetic field functions should be gradually refined,thus achieving comprehensive description of the gravity and geomagnetic field information of islands,reefs,and their neighboring areas.High-precision models and reference maps of Earth's gravity field/geomagnetic field,ca
