中文摘要：

出于保障数据安全的需要,利用安全网闸形成内外网络拓扑结构,是在很多具体的业务应用中的常见手段.如何能够在这类网络结构下,实现不同类型、粒度的数据资源整合与共享,是当前水利数据资源整合工作的难点之一.针对这一问题,以南水北调工程为具体应用背景,重点解决内外网间数据资源整合问题,提出多粒度工况对象模型,并在此基础上建设基于Solr Cloud的分布式整合数据检索引擎及统一资源发现平台.该研究也是推进水利信息资源整合共享进程的有益探索.

英文摘要：

In order to keep the data security, using the network gateway to make up internal and external networks, is used frequently in many water conservancy projects. Under such circumstance, integrating and sharing data resources with different data types and granularity are difficult and it is studied often in many researches. Regarding this specific issue, and in order to integrate data resources separated in internal and external networks, this paper uses the South-to- North Water Diversion project as the application background, proposes a multi-granularity object-oriented data model, and then builds a distributed integrated data index and a uniform resource discovery mechanism based on the Solr Cloud Framework. And it also promotes the process of water conservancy information resources sharing.
