长白山多源空间数据集成研究

摘要

As an international boundary mountain between China and North Korea,Changbai Mountain has been highly concerned in international community by its special geographical location,famous vertical distribution belts of vegetation and ecological sensitivity.In the light of multi-source attribute of Changbai Mountain spatial data,the source of multi-source spatial data and the function to be realized by Changbai Mountain multi-source data integration,this paper compares the commonly used modes of multi-source spatial data integration,discusses the feasibility of integrating Changbai Mountain mulit-source spatial data using Geodatabase model by ERSI company,and forecasts the prospect of multi-source spatial data integration.%长白山作为中、朝两国界山其特殊的地理位置,以及罕见的植被垂直分布景观格局,向来是国际上高度关注的生态敏感地区（如图1所示）。本文针对长白山空间数据的多源性特征,多源空间数据的来源及长白山多源空间数据集成要实现的功能,对常用的几种多源空间数据集成模式进行比较,提出了采用ESRI公司的Geoda-tabase数据模型进行长白山多源空间数据集成的可行性,并对多源空间数据集成的前景进行了展望。
