摘　　要：基于重力测量信息化建设的目的,在对重力场信息深入分析的基础上对多元化重力场信息服务及其应用进行了研究。建立了以多元化重力场信息为基础,集数据存储、处理、分发和应用于一体的服务体系。研究结果表明,构建基于多元化重力场信息数据库的重力场信息服务系统,能够使海量重力场信息的管理更科学、使用更高效、空间分布特性表现更直观;满足了重力场研究和应用部门的数据服务要求;实现了海量重力数据获取、处理和管理的自动化;提高了工作效率。Aiming at the information construction of gravity surveying, this paper made a detailed study of the multi-source information service of the gravity field as well as the applications through a thorough analysis of the gravity field information, and built a service system which integrateed data storage, processing, distribution and application based on multi-source gravity field information. The research indicated that the construction of the information service system based on multi-source gravity field information enableed the management of enormous gravity field data to be more effective, the use to be more efficient, and the spatial distribution characteristics to be more intuitionistic, and satisfies the requirements of gravity field research and application departments, which realized the automation of the collection, processing and management of enormous gravity data and enhanced work efficiency.
