人口密度影响因素的可视化分析——以重庆市教育文化产业为例

Visual Analysis of Influencing Factors of Population Density——The Education and Culture Industry as an Example in Chongqing

随着城市化发展的推进,城市人口密度越大,越来越多的人涌入城市。在城市人口密度大的当今社会,一些因素往往会引起局部地区人口密度增加,形成局部人口密集区域。引起人口密度增加的因素很多,教育文化产业就是原因之一。近年来对于人口密度的分析,主要是通过对DMSP/OLS夜间灯光数据进行分析,对人口密度影响因素的研究很少。而本文通过热力图和灯光数据对人口密度进行分析,确定教育文化产业分布情况对人口密度有着重要的影响。

With the development of urbanization,the density of urban population is increasing.More and more people are pouring into the city.In today’s city with a large population density,some factors often lead to the increase of population density in some areas,and form a densely populated area.There are many factors that lead to the increase of population density,and education and culture industry is one of the reasons.In recent years,the analysis of population density,mainly through the DMSP/OLS night light data analysis,the impact of population density factors are very few.In this paper,the population density is analyzed by thermal chart and lighting data,and the distribution of education and culture industry is determined,which has an important impact on population density.
