基于信息关联的城市人口空间分布建模方法研究

以福州市三环以内及周边范围的户籍人口数据为样本,探讨城市人口空间分布建模方法与相关的数据处理流程.运用Arc GIS的空间分析功能,得到实际人口分布状况的可视表达;采用可能出现的7种函数表达式拟合实际的人口分布曲线、对比各函数表达式的拟合误差.结果表明,利用指数函数与加幂指数函数建立的福州市的人口空间分布模型具有相对优势.

The research on methods of modeling spatial distribution of urban population and their application

Take the registered population data within the range of Fuzhou Sanhuan road and its surrounding as sample, this paper discusses the methods of modeling spatial distribution of urban population and related data processing flow. Firstly, using the spatial analysis function of ArcGIS to get the visual expression of actual population distribution; then using seven kinds of possible function expressions to fit the actual population distribution curve, comparing with the fitting error of each function expression,the results show that using the exponential function and add-power exponential function to establish the population spatial distribution model of Fuzhou have a comparative advantage.
