Abstract: Statistical analysis of Fe abundances gradients is one of the important parts of chemical evolving research of the Galaxy under grid environment and is one of exemplifications of deep-going analysis and process based on physical data resources for virtual observatory application system. Statistical analysis of Fe abundances gradients in the Galaxy based on grid environment implements grid services including registry service, data service, stellar orbit calculating service and visualization service. All these grid services constitute an integrated grid application system. This paper describes the design and implementation of grid data service, stellar orbit calculating service and visualization service in detail. By this demonstration, it shows how to promote resources sharing via grid service under distributed, heterogenous and dynamic grid environment.
