Study on the Temporal and Spatial Patterns of Environmental Quality in China and Its Influencing Factors Based on Two Perspectives of Pollution and Absorption

Based on the two perspectives of environmental pollution and environmental absorption, combined with the regional differences of environmental quality influencing factors, SDM model is used to analyse the influencing factors and spatial effects of environmental quality in China and all regions. The research shows that the spatial agglomeration characteristics of environmental quality are obvious, and the problem of regional imbalance is prominent. The environmental quality and economic development in the eastern region are gradually harmonized, but population agglomeration has a greater negative impact on the environment. The development model of "high investment, high energy consumption, high pollution and low efficiency" in the central and western regions has become a constraint to improve environmental quality.
