摘要
针对传统方法解决城市内部人口空间分布问题的困难和不足,在分区建模基础上,提出了将兴趣点引入多元逐步、地理加权、混合地理加权方法,以天津市15区为实验区,进行模型验证。结果表明,兴趣点可以有效地反映人口空间分布现状,地理加权方法能更好地模拟人口的空间分布。
Aiming the difficulties and shortcomings of conventional approaches in solving the spatial distribution of urban population,this study adopts partition modeling to raise the idea of introducing interest points to multi-dimensional stepwise,geographical weighting and mixed geographical weighting.The 15 districts within the jurisdiction of Tianjin were selected for the trial to validate the model.As revealed by the results,the interest points were effective in indicating the current state of how the population is distributed from a spatial perspective and the geographical weighting method is superior in the simulation of spatial distribution for population.
