摘要
本文主要研究城市人口空间分布模型在长春市区的应用,目的在于模拟长春市区人口的空间分布情况。本文参考前人研究的基于城镇面积的城市人口密度系数模型,同时考虑交通网对城市人口分布的影响,提出适合长春市区人口空间分布的模型,生成100m(100m网格的人口数据空间分布图。为验证该模型的准确性,将建模所得数据与人口统计数据以街道为单位进行对比,发现模拟结果与调查数据基本相符。
Taking Changchun city as an example, this paper mainly studies the spatial distribution model of urban population. Changchun＇s population is simulated by a mathematic model, and a spatial distribution grids with the cell of 100m - 100m is built. To validate the veracity of this model, the paper compares the result with census data, and finds that this model can almost exactly simulate the spatial distribution of Changchun＇s population.
