在环境地学研究中应用GIS急需解决的问题分析
Problems of the Application of GIS in Geo-environment Study
【摘要】 地理信息系统已经成为环境地学的常用工具 ,但主要被用来存储和显示地图 ,没有发挥其应有的功能。本文认为多源空间数据集成、空间数据分析和挖掘以及模型集成等是其中三个最主要问题。多源环境数据集成是基础 ,空间分析是连接多源数据集成与模型集成的桥梁和纽带 ,数据通过这个桥梁传输给模型 ,模型对环境系统进行模拟和仿真。这些问题的解决有利于更好地在环境地学中应用地理信息系统
【Abstract】 GIS is becming a common tool in the geo environmental study,which is used to display and store data for geo environment.But some problems have not been sloved.The paper discusses three main problems needing to be solved,that is spatial data integration,spatial analysis and method integration spatial data integration is the base,spatial analysis is the bridge between method and integration,method could simulate the run of the geo environment system.If those problems were solved,it would do good to use GIS in geo environment study.
【Key words】 GIS; eco environment; data integration; spatial analysis; method integration;
