高亚洲寒区地理信息系统中积雪数据库系统的研建

A Study of Seting up the Accumulated Snow Database System in the GIS of the High-Asia Frigid Region

随着计算机技术和地理信息系统技术的发展,其应用也日趋广泛,尤其是在地学动态监测与多学科分析方面,它不失为有效手段。根据中国科学院“八·五”特别支持项目——高亚洲冰冻圈动态变化基础研究的需要,进行冰冻圈数据库系统的研究。为适应高亚洲寒区地理信息系统的建设,本文重点就积雪数据库建设的必要性、积雪数据分类及其指标体系、积雪数据库系统的结构和功能设计、分析模型程序库以及积雪数据库的应用进行探讨。

Following the development of computer technology and GIS technique, their application becomes more extensive. Especially in the geography dynamic monitoring and multi-sciences analysis, they are effective ways. Cryospheric database system is studied for the basic researches on the dynamic change of High-Asia cryosphere, which belong to the specially supported project by the Chinese Academy of Sciences during the Eighth Five-Year Plan. For the construction of GIS in the High-Asia frigid region, the accumulated snow database, classification of accumulated snow data and its parameter system, the configuration of the function design of this system, procedure base of analysis model, and the application of this database are discuassed in this paper.
