[0060] see Figure 1-7 .
[0061] Such as figure 1 As shown, a population data spatialization method based on partition modeling provided in this embodiment includes the following steps:
[0062] S101. Collect the permanent population data of the research area and the original data sources that affect the spatial distribution of the population, and perform data preprocessing;
[0063] Specifically, for step S101, the original data sources such as permanent population data, natural and socio-economic factors affecting the spatial distribution of population, etc. are collected from 106 streets in Yuexiu District, Haizhu District, Liwan District, Tianhe District, Baiyun District, and Huangpu District in Guangzhou. . Such as: land use data, DEM, POI data, road network distribution, night light data, residential housing prices, building area, etc.
[0064] S102. Perform grid processing on the preprocessed data based on the geographic detector model, standardize the correspondin...

[0124] see Figure 3-8 .
[0125] Such as Figure 8 As shown, this embodiment also provides a population data spatialization system based on partition modeling, including:
[0126] The data preprocessing module 100 is used to collect the resident population data of the research area and the original data sources that affect the spatial distribution of the population and perform data preprocessing;
[0127] The identification factor module 200 is used to perform grid processing on the preprocessed data based on the geographic detector model, standardize the corresponding population distribution impact indicators after obtaining them, and preliminarily screen out the population distribution impact factors;
[0128] The screening factor module 300 is used to divide the research area into several subregions, and according to the differences in natural and socioeconomic factors between the subregions, on the basis of the preliminary screening, the impact on the population distrib...
