Research on Urban entity boundary and virtual boundary based on GIS--Taking Dujiangyan City as an example
2021
Overview
This paper uses the Point of Information (POI) point of interest and population distribution feature data in Dujiangyan City as the basic data, and uses spatial analysis methods, such as nuclear density analysis, contour analysis and standard deviation ellipse, to study the correlation between the entity and virtual boundaries of Dujiangyan. The results show that the urban entity and online activity intensity of Dujiangyan spreads around Xingfu, Guankou, and Puyang. The entity boundaries of the city and the virtual boundary in these three areas overlap basically, except for the city of Dujiangyan. The entity and online activities are not balanced in intensity, and there are obvious dividing lines in the area near Longchi. The entity and virtual boundaries of the city are quite different in Qingcheng Mountain and Juyuan.
