摘　　要：如今基于GIS的水利应用往往存在海量数据的分布式存储杂乱、平台构建难度大、并发访问需求大等问题,要解决这些问题,可考虑将GIS与云计算相结合,利用云计算的弹性、多租户模式、易维护等特性,以及GIS的数据平台统一管理、空间数据存储方便、可共享性高等特点,构建水利地理信息服务平台。从云GIS基本理论出发,结合虚拟化技术及云的3种服务模式,提出江苏省水利地理信息服务平台的原型设计方案,并初步实现水利信息资源共享机制,旨在为今后地理信息系统在水利行业的建设摸索一条可行之径。Now water conservancy applications based on GIS have the problem of disorderly distributed storage for huge amounts of data, difficult platform construction and the large demand of concurrent access. To solve these problems, the combination of GIS and cloud computing is considered, to build water conservancy geographic information service platform.GIS has the features of flexibility, multi-tenant model, easy maintenance and other features. And GIS has features as unified platform for data management, facilitate spatial data storage, sharing high, and has been widely used in water conservancy informationization. From the basic theory of Cloud GIS, combining with three service models of virtualization technology and cloud, and selecting CloudStack as cloud platform, the prototype design of Water Conservancy Geographic Information Service Platform of Jiangsu Province is proposed. It initially realizes the water resources information sharing mechanism, aiming to explore a feasible path for the future of GIS construction in water conservancy industry.
