摘　　要：提出了基于Internet的空间数据和非空间数据分布存储的空间数据仓库模型,并将其与数据挖掘技术相结合,开发了基于Internet的农产品市场行情时空演变可视化信息系统。该系统由来自Web网页的数据源、驻留Web数据自动抓取工具和非空间数据库的服务器以及驻留空间数据库、具有可视化展示和空间数据挖掘功能的客户机组成。为提高系统客户机的运行效率,系统采用了多种策略,如分布存储策略、瘦客户机策略、模糊匹配以及批处理策略等。系统具有界面友好、操作简便、可视化程度高等优点。This paper proposes a model of spatial data warehousing based on Internet and distributive storage of spatial data and non-spatial data. The model combined with data mining technology, a visual information system of time-space evolution of the agriculture products market is developed. The system consists of data sources from Web, a server where an acquisition tool of Web data and a non-spatial database are located, and a client end where a spatial database, components for data visualization and data mining are included. In order to improve the performance of the client of the system, several strategies are adopted, such as distributive storage, thin client, fuzzy matching, batch processing and so on. The system has the properties of friendly interface, simple operation and high visualization.
