人口普查地理区域自动划分技术研究

Research on automatic division of population census district

针对中国现阶段人口普查模式和基础地理数据的拥有现状,该文总结归纳了国际上现有人口普查地理区域划分的技术和方法,比较了它们各自的优缺点,提出了基于Delaunay三角网对人口普查区域自动划分的技术。介绍了Delaunay三角网的特性及其空间划分的理论基础,论述了基于Delaunay三角网的人口普查区域划分技术、方法、过程和步骤,最后给出了该技术实验和应用实例。

Aiming at current status of China's current census model and basic geographic data,based on the theory and technology of Delaunay triangulation dividing,the census district was automatically divided with line feature as constraint condition.The characteristic of Delaunay triangulation was introduced,the technologies,measures and processes of census district division were discussed in the paper.The application example was given finally.
