中文摘要：	信息资源整合是目前信息资源管理的研究热点，本研究提出运用信息可视化方法指导信息资源整合，采用信息可视化思维进行信息资源整合，实现信息资源的有效增值。 本研究采用文献调查法，研究了国内外信息资源整合的相关文献，发现信息资源整合的不同层面需要不同的技术，这些技术实现了不同的功能，它们相互关联、相互作用、相互促进。利用信息可视化可以实现信息资源表现层的整合。信息可视化实现信息的知觉化、感知化，用于更好地理解大规模信息及其本质、更方便地操纵信息。在处理信息的可视化空间内，可以显示和观察信息的属性，被显示对象之间的隐藏关系变得显而易见。但是目前研究基于信息可视化的信息资源整合的文章较少。 在信息系统设计模式中，框架是一个系统全部或者部分的可复用设计。本研究拟对现有情况进行梳理，找出目前信息资源整合项目的普遍性和共同点，提出信息资源整合框架。在此基础上，根据信息可视化的实现过程，提出基于信息可视化的信息资源整合框架。从信息资源描述可视化、信息检索可视化、信息提供可视化三个方面分析了信息可视化在信息资源整合中的功能实现。 信息资源整合是一项系统工程。本文分析了目前图书馆信息资源整合对象、技术，根据提出的框架，将信息可视化应用于图书馆信息资源整合，提高图书馆信息资源的利用效率。设计了一个应用信息可视化进行馆藏数据库和电子图书的整合系统。关于元数据的整合，利用863字段实现。信息可视化视觉设计选择了用树形图表示，用空间定位体现书目信息之间的关系，用空间节点的临近度和布局表达主题词之间的相关度，用节点连接线表示主题词之间的层次关系。
英文摘要：	Information resource integration is a distinctive field in which more and more people who engaged in information resource management take interest． The author plans to use information visualization to integrate information resource in this study． In this study, the author uses a method of literature survey． The author have studied the relevant literatures of information resource integration at home and abroad and have found that different technologies are required at different levels of information resource integration to achieve different functions． Those technologies achieve different functions and they are interrelated and interactional and promoted each other． Information visualization can achieve the performance of information resource integration at representation layer． Information visualization can actualize perception of information, give you a better understanding of large-scale information and the nature of information and manipulate information more convenient． In visual information space, you can display and observe information attributes． So you can find the relationship hided in the information resource． However, there is lack of researches about information resource integration based on information visualization． In the model of the design of information system, the framework is all or part of a system of reusable design． In this study, the author wants to make a pectination about the existing situation in order to find the universality of current projects of information resource integration． The author gives a framework of information resources integration on this basis． In accordance with the realization process of information visualization and based on this framework, the author puts forward the framework of information resource integration based on information visualization． The author analysis how to achieve information visualization in process of the information integration from three aspects visualization for information description, visualization for information retrieval, visualization for information access． Information resource integration is a systematic project． At last this paper analyzes the object of information resource integration in library and technologies． According to the proposed framework, information visualization is applied to integrate library information resource． The author designs integration system of OPAC and e-book database based on information visualization． 863 fields are used to achieve the integration of meta-data． Shape of tree is chosen as the method of visual design． Spatial location reflects the relationship between information about books． The layout of space nodes embodies correlation of subject． The links of the node incarnate the level of relations between subject words．
