欧亚大陆山地垂直带谱数字集成框架

A Framework for Digitally Integrating Mountain Altitudinal Belt Spectra in the Eurasian Continent

欧亚大陆是山地垂直带谱多样性和复杂性最集中的区域,在世界山地垂直带谱体系中具有十分重要的地位。针对当前山地研究数据集成相关的研究计划和山地垂直带谱研究中存在的问题,指出进行欧亚大陆山地垂直带谱数字集成的必要性和重要意义;探讨了欧亚大陆山地垂直带谱数字集成的框架体系,包括数字集成的方法、数据库框架结构与内容、技术流程等;详细阐述了数据收集与预处理、分类系统的建立、数据提取、元数据建设、数据存储方式等技术流程;建立了欧亚大陆山地垂直带谱数据库,包括5个专题空间数据库和元数据库;指出了该数据库对山地垂直带谱及相关研究的意义;总结了数据库建设过程中需注意的问题;展望了进一步的发展方向。

Eurasian continent is considered to be the best study area for mountain altitudinal belt spectra （MABS） researches thanks to its MABS＇ magnitude and diversity. By analyzing the recent tendency in mountain research field and requirements of MABS related research field, this paper points out that it is urgent to spatially integrate the MABS data accumulated in literatures. For this, the paper presents a framework for digitally integrating the MABS in Eurasian continent. Three elements of the framework, including integration method, architecture designing and technical process are discussed. Then the paper illustrates several key procedures of technical process, including data collection and preprocessing, construction of a classification system, data standardization, metadata creation and data storage solution, etc. A spatial database for MABS of Eurasian continent which contains five thematic dataset and metadata is established. At last the paper summarizes problems during database construction and shows the prospects of further study.
