黄土高原植被资源数据网络共享系统

Information Sharing System of Vegetation Resource on Loess Plateau

在总结黄土高原生态环境与植被营造方面成果与经验的基础上,研发了一个由多专题、多形式数据组成的黄土高原植被资源数据仓库系统。本系统采用基于Internet的分布式数据仓库技术,在网络环境下建立一个包括黄土高原环境背景、植被种质资源、植被营造技术、植被与水保措施减沙效益等内容的植被资源数据共享系统,同时运用数据挖掘等原理与技术对数据库中的数据进行深层次的处理,使系统具有数据查询功能、决策支持功能和维护功能,为黄土高原生态环境改良提供宏观决策层面、技术支持层面、普通用户层面上的信息支持。

By summarizing the research results and experiences on ecology environment changing and vegetation rebuilding in the loess plateau, this paper established a compositive data warehouse consisted of many special topics and data forms. The information sharing system is designed based on the internet network and distributed share system techniques, and including much more vegetation resource data of loess plateau, such as vegetation distribution, composition, function, vegetation resources bearing capacity, water and fertilizer transferring processes in vegetation rebuilding and so on. At the same time, by using of the data mining and other technique, the data in the data warehouse has been more precessed. So the system can offer scientific support for macroscopical policies decision, technology supports and common users for realizing hills and plains beautiful in the loess plateau.
