摘要
主要以当前南沙大开发下的生态保护为背景,提出了以“三库一体模式”实现基于ArcGIS的南沙生态数据库系统的思路,即首先建立南沙多源海量生态数据库,然后以生态模型为主导,调用生态分析方法,提取数据库中的数据进行相关计算,对模型进行求解,辅助专家进行决策。同时数据库中各类数据以及决策分析结果可以通过网络发布,以达到信息共享的目的。
This paper aims at the ecological protection in the process of Nansha construction, and proposes a solution on how to realize the Database System of Nansha Ecology on ArcGIS on the basis of three warehouses of integrative modes. Firstly, it builds the huge multi - source Database of Nansha ecology. Then it takes ecological model as the leading factor to transfer ecological analysis method, query the relevant data and calculate it, solve the problem of model and assist the expert to make decision. The data and analysis result can be published using the lnternet for data sharing.
