中文摘要	通过对寒区旱区资源环境研究中已积累的大量特色数据、应用模式和程序的分析，对分布式网络环境中的数据采集与管理、应用模式和程序的移植集成、应用程序与数据的交互访问等技术进行了讨论，提出建立由数据中心、中间件服务、应用服务、一站式管理组成的数据平台是提高数据利用效率，方便实现数据与应用集成，提高科研效率的一种有效途径之一．对数据平台建设的主要思路及实现技术进行了详细讨论，并在实验基础上，初步建立了基于曙光3000高性能计算环境的寒区旱区资源环境数据平台，为以后的数据网格建设做了一定的技术准备．
英文摘要	A mass of characteristic data, application modes, computing programs and data analysis software has been accumulated in the long-term scientific research on resources and environments in cold and arid regions. How to effectively manage these data and integrate them with application programs, and how to provide an easy platform for scientific researchers to use these data and solve their problems with integrated models must be especially considered. In the distributed network environments, some techniques based on the Dawning 3000 high - performance computer have been studied in this paper, such as data collection and management, transplant and integration of application models and programs, data access between computing programs and database. Through testing, it is suggested that the data platform of resources and environments in cold and arid regions based on high - performance computing environments is a valuable method for improving data application and application models of cold and arid regions. The data platform consists of data center, middleware service, integrated application program service and one stop service. According to data grid concept, the general structures, the main functions and the fulfillment ways of the data platform are discussed in detail. The data in the data center, managed by Oracle database, can be divid-ed into relation data, binary data, text data and spatial data. The middleware service, which supplies an access to the interface between data center and application service, is designed with three sections: message - oriented middleware, data access middleware, and transaction processing middleware. The application services are requested by integrated application models, application modes, and application programs such as MM5, SSIB, SME3, and ANSYS etc. The presentation, management, request, execution of data and their application are fulfilled thought one- stop service, which were built with three - tier architecture of Brower- Compute Service Agent- Server. The input parameters of the application software are packaged in a browser with Java Applet, and then passed to the middle- tier to form a batch of commands, which starts the application software on the server tier.On the basis of tests, a single prototype of data platform is preliminarily established based on a kind of application modes in the high- performance computing environments, and is able to serve the researchers. The data platform, managed by one-stop service, is supported by the data of the distributed environments for researching the resources and environments in cold and arid regions.
