人口数据空间分布化模型研究

Investigation on the Model for Spatial Distribution of Population Data

分析人口数据地理空间分布化的必要性,针对常用的表示人口分布方法的不足,提出将人口数据分布到规则格网上的数字人口模型(DigitalPopulationModel,简称DPM),并详细阐述了DPM建立的原理及实现的技术方法,以及目标区域格网划分的原则、方法。通过样区实验,证实该方法表示分布人口的准确性、合理性。

The importance of spatial distribution of population data is analyzed in this paper, and the Digital Population Model (DPM),in which the population data are distributed on the grids, is proposed with consideration to the shortages of traditional population distribution methods. Furthermore, the theory, algorithms of establishing DPM and the methods to determine the size of the grids are introduced. At last, the rightness and precision are testified via the experiments.
