摘　　要：全面系统了解青藏高原多年冻土本底资源,对青藏高原多年冻土科学研究有重要意义,也为工程建设、资源开发、生态和环境保护提供基础性科学数据。正在执行的科技部国家基础性工作专项"青藏高原多年冻土本底调查"将产出数量大、种类多的冻土本底数据。本系统为该项目设计了一个数据管理和应用的Web系统,同时也考虑了已有数据积累的归档管理。目前包括钻孔、物探、土壤、植被、监测、空间数据等六大类数据,物理实现为23个数据表。系统包括录入、管理、查询、显示、分析与应用5个主要功能模块,提供了列表、图表、地图等一系列数据可视化手段。介绍了系统和功能设计、数据库设计以及关键技术,最后列举了基本的数据应用示例。目前,温泉调查区的数据已经录入该系统,随着项目的开展,将有更多数据进入本系统,数据分析应用也将更为深入。研究结果为今后类似冻土数据库设计和实现提供参考价值。Comprehensive and systematic permafrost background data play an important role in the Qinghai-Xizang （Tibet） Plateau （QTP） permafrost research,offering basic scientific data for engineering construction,resource development, and ecological and environmental protection over the QTP. The ongoing work of National Infrastructure Project funded by the Ministry of Science and Technology of China titled ＂Investigation of permafrost and its environment over the Qinghai-Xizang（Tibet） Plateau＂ will output a large amount of varied data from frozen soil background investigation. The system is specifically designed and developed as a data management Web application for the outputs of this research project, as well as for existing frozen soil data. Currently it manages drilling data, geophysical investigation data, soil profiles, vegetation investigation data, environmental monitoring data （including frozen soil active layer data, flux data, ground temperature, and meteorological observation data）, and spatial data covering the study area. The 6 categories data are physically implemented as 23 data tables. The system includes 5 functional modules, i. e. , data input, management, query, display, and analysis and application modules. A variety of data visualization approaches have been implemented. We present the system and functional design, database design and key technology involved in the system implementation. Exemplary applications are also demonstrated. So far investigational data from the Wenquan field work conducted last autumn have been ingested into the system. More data will come into the system as the project advances. The paper offers a good example to future similar work to implement a frozen ground data and information system.
