广州市人口密度分布及演化模型研究

Modeling the Spatial Distribution of Urban Population Density and Its Evolution in Guangzhou

根据广州市第三、四、五次人口普查资料,运用GIS技术对空间数据进行提取,然后对广州城市人口密度分布进行数学模拟和比较。结果表明,1982年以来广州市人口密度呈现典型的Clark分布,而且随着时间的推进,其拟合程度越来越高,今后将逐步向Newling模型演变。

On the basis of the third, fourth and fifth population census and implying Geography Information System technique to get spatial data, the author studies and models the distribution of urban population density and its evolution in Guangzhou. It is indicated that the Clark Model can best describe spatial distribution of urban population density and its evolution since 1982 in Guangzhou, and with the lapse of time, fit of the model become better and better. In the future, this Clark Model of population density will evolves into the Newling model.
