Correlation characteristics and prospects of construction land and population changes in Shanghai
The systematic study of the spatio-temporal coupling relationship between construction land and population serves as a theoretical basis for optimizing and adjusting policies related to construction land and population,ultimately enhancing the efficiency of land resource utilization.Utilizing four sets of census data since 1990 and multi-temporal land use remote sensing monitoring data,this study analyzes the spatial and temporal changes and coupling relationships between construction land area and population in Shanghai's urban area and its 16 administrative districts from 1990 to 2020,based on the population-construction land change rate model.The research findings are as follows:(1)Over the past 30 years,both construction land and population in Shanghai have expanded significantly,marked by intense change intensities,and exhibiting typical sprawl characteristics.(2)The population and land use changes in all 16 districts of the city simultaneously show spatial differentiation and geographic adjacency features.(3)While the intensity of changes in the suburban and outer suburban areas first increases and then decreases,some central urban areas experience a decrease in both population and land use.The results of the study reflect a phased characteristic of"compensatory initiation,expansive development,and contraction equilibrium"in the population and land use changes in Shanghai over the past 30 years.The study introduces concepts and calculation methods such as change intensity and elasticity for the first time,and incorporates geographic information to enhance result visualization.The research conclusions provide an evaluation method and value orientation for the relationship between people and land in mega-cities,offering reference for relevant policy formulation and planning.
