Abstract:
At the time scale of three census, the quantity change, spatiotemporal characteristics and influential factors of floating population in Shaanxi province were studied based on the date of floating population and socio-economic indicators by using three-dimensional simulation, global spatial autocorrelation analysis model and local spatial autocorrelation of ArcGIS. The results showed that the number of floating population in Shaanxi province is increasing and the proportion of floating population to the resident population is growing evidently. The spatial distribution of floating population is unbalanced, and its relative gravity center moved northward gradually. Floating population distribution appears autocorrelation gradually, and its spatial aggregation enhanced and formed three gathered zones, that is, high-high density in northern Shaanxi province, high-low density in Guanzhong and low-low density in southern Shaanxi province. The development of mineral resources, three industrial development and favorable living conditions of inflow place mainly affect spatiotemporal differentiation of floating population in Shaanxi province.
