文章分析了国外对地观测数据处理中心的发展趋势，指出了我国对地观测数据管理中存在的问题与差距，提出了我国对地观测数据中心的建设方案：建立数据处理中心并提供深层次服务；建立数据共享机制，促进数据共享与服务；资源优化与整合。为了促进陆地观测数据共享与应用，必须建立国家陆地观测数据中心，建立的数据中心包括数据处理、归档、分发与服务。国家对地观测数据中心必将改善对地观测数据共享与应用，满足对地观测数据的需求。

This paper discussed the developing trend of the foreign land observation data processing center and the problems of our country land observation data management. The developing trend of the foreign land observation data processing center are: building up the concentrative data processing center and providing comprehensive service;building up the data sharing mechanism, improving the data sharing and servicing;reforming and integrating data resources. In order to improve the land observation data sharing and applications, it is necessary to build up the national land observation data center. The construction of the national land observation data center includes the facility of comprehensive data processing, archiving, distributing and service and so on. The national land observation data center will improve the land observation data sharing and application; satisfy the requirement of land observation data.
