With the development of technologies and the implementation of large quantity of astronomical observation projects, astronomy faces data avalanche and has entered an information era. A basic aim of the Virtual Observatory is to provide uniform access to highly distributed, complicated, huge astronomical datasets, and to realize federation of global astronomical data resources, so that astronomers can obtain required data efficiently and conveniently for their research. China Virtual Observatory (China-VO) project designs and implements astronomical data access services based on Grid technology, and provides uniform interface to Grid client application. In this paper, we introduce the data access service toolkit development using Globus Toolkit, the Grid services encapsulation of catalogs according to the latest astronomical data standards recommended by International Virtual Observatory Alliance, the implements of catalog Cone Search access service. Furthermore, we also introduce how to construct other Grid services using above data access services.
