The purpose of Grid is to build a platform for Clients sharing the different resources. The precondition of resources sharing is to describe, store resources information such as location, attribute, usability etc and to provide the interface for accessing. All these are very important problems in the field of Grid Research, which is called "Grid Information Services". The main functions of Grid Information Service are to discovery, register, query and modify the resources information, providing a actual and real-time dynamic reaction in the Grid computing environment. The information it processed is description of every resource (includes: data resources, computing resources etc), services and other entities in the Grid computing environment. As the important role in the Grid Application, The Grid Information Services System is the core in Grid Design.The foundation of the Grid resource information services is the structure of resource information services, Services-oriented Grid application services and their interfaces. This paper firstly introduces the framework of the Grid resource information services based on the Globus and correlative technology, does the research on the resources discovery mechanism combined the Globus with P2P networks, which is considered either the features of Grid resources or the effective search technology in the P2P networks. Then we bring forward a new Grid information model used P2P to extend the GT4 information services, and make the particular design of the resource discovery services in this model, including the main components design of the model in a Grid runtime supported environment, the approach and interfaces design. At last we did the model simulation and compare it with other systems. It could improve the efficiency of the resource discovery and realize the resources sharing better than others.
