文章以中科院兰州文献情报中心开发的CSpace DR为研究对象，主要介绍和研究了CSpace DR所应具备的专业领域知识资源整合功能。研究发现，尽管CSpace DR通过知识发现和知识组织向用户提供多维度的异构知识资源整合服务，但CSpace DR对于异构知识资源的实体规范处理以及知识资源遴选评价体系构建方面还有待提高之处。

Taking CSpace DR developed by Lanzhou Literature and Information center of the Chinese Academy of Sciences as the research object, this paper introduces and studies the integration function of knowledge resources in the professional domain that CSpace DR should have. It is found that although CSpace DR provides users multi-dimensional heterogeneous knowledge resource integration services through knowledge discovery and knowledge organization, CSpace DR has yet to improve the entity specification processing of heterogeneous knowledge resources and the construction of knowledge resource selection evaluation system.
