中文摘要	随着黑河流域时空数据的快速增长,已有的黑河信息系统在共享效率、数据分析及平台架构等方面存在缺陷,已无法满足现实的需要。本研究针对目前平台的缺陷重新设计新版数字黑河信息系统(NDHRIS)的整体框架,从观测、数据及模型三个角度实现新版数字黑河信息系统的新功能。首先从基础设施、服务及应用三个层面介绍系统整体设计,其次详细阐述系统实现的关键技术及功能改进,最后,讨论了该系统仍然存在的问题及未来发展方向。目前该系统已业务化运行,数据量超过5 T,共1 058条元数据,向大约100个研究所和50个项目提供了大约8 TB数据集和5 000个数据服务,有效提升了黑河流域科学数据的共享效率,支撑全球寒区监测计划的实施。
英文摘要	TheDigital Heihe River Basincan be considered as an implementation of the Digital Earth concept in the Heihe River basin,the second largest inland river basin of China. The Digital Heihe River Basin is composed of an information infrastructure and its applications. The former is further built up by a data integration platform,a modeling system and an automatic observing system,and the latter are various applications using integrated models and decision support systems. With the rapid growth of the spatio-temporal data of Heihe River basin,some existing Heihe information service systems have defects in the aspects of sharing efficiency,data analysis and platform architecture,etc.,which can no longer meet the practical needs. In this study,the overall framework of the new digital Heihe information system(NDHRIS)is redesigned to address the defects of the current platform,and the new functions of the new digital Heihe information system are realized from three aspects:observation,data and model. In this paper,the overall design of the system is introduced from three levels:infrastructure,service and application. Secondly,the key technologies and functional improvements of the system are described in detail. Finally,the existing problems and future development directions of the system are discussed. At present,the system has been operational and includes a lot of data with key variables of cold and arid regions in China,such as glacier,snow,frozen soil,desert,model datasets such as surface atmospheric forcing,soil texture,plant functional type map,eco-hydrology remote sensed products,and comprehensive dataset in Heihe River basin. It has a data volume of more than 5 T and a total of 1 058 metadata,providing about 8 TB data sets and 5 000 data services to about 100 research institutes and 50 projects,effectively improving the sharing efficiency of scientific data in Heihe River basin and supporting the implementation of the global cold monitoring plan.
