摘　　要：为了实现对公开服务接口的空间资源的统一化集成和发现,对空间资源的统一发现关键技术进行研究;根据空间资源的特征,提出了一种基于CSW的空间资源统一化发现服务实现框架;实现了一个基于该框架的原型系统,并进行了相关实验。实验结果表明,基于CSW的空间资源统一化发现服务能够很好地实现异构空间资源的共享和协作。To implement the integration and unified discovery spatial resources with open service interfaces and serve for resources users, a systematical research of the key technologies is made to construct unified discovery and service of spatial resources; then the features of spatial resources are considered, it a framework of unified discovery and service of spatial resources is designed, based on the CSW （catalogue service for web） specification which is made by OGC（open geospatial consortium） ; Then, a prototype of unified discovery and service of spatial resources is implemented. At the end, a related experiment is carried out, and the result shows that unified discovery and service of Spatial Resources based on CSW can greatly facilitate the share and cooperation of different resources.
