摘要
在总结黄土高原生态环境背景与植被营造方面的研究成果与经验的基础上,采用基于Internet的分布式数据库管理系统模式,在计算机网络上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库系统,同时运用数据挖掘技术等对数据库的数据进行深层次的处理应用,研制开发了一个由多专题、多种形式数据组成的黄土高原植被资源数据仓库系统,以期为黄土高原生态环境与退耕还林工程提供科技决策支持。
Research results and experiences of ecological environment changing and vegetation rebuilding on the loess plateau, establishing a compositive database composed of many special topics and forms. The data warehouse is based on the internet, and in the computer internet we establish a vegetation resources data warehouse including loess plateau vegetation distribution, composition and function, vegetation resources bearing capacity, water and fertilizer transferring processes in vegetation rebuilding and others, at the same time the data in the database are also more handled and used with the help of artificial intelligence theory, expert system technique, data mining technique and other technique, for realizing hills and plains beautiful offer scientific information support for macroscopical policies, technology supports and common users.
