A Study on the Spatial and Temporal Distribution of Population in Yunnan Province Based on BigDate

Based on the data collected from the fourth, fifth and sixth census of administrative units at county level in Yunnan Province, the temporal and spatial distribution of its population is studied and analyzed with the spatial analysis function of ArcGIS and the method of geostatistics. The normal distribution of population density data is explored and analyzed with the help of histogram, normal QQ chart and Voronoi chart. From the results, it can be found that the population distribution of Yunnan Province is not balanced. The population distribution of central Yunnan, mainly in Kunming, is concentrated, while the population distribution is relatively concentrated in northeast and Southeast Yunnan and relatively sparse in northwest and Southwest Yunnan.
