Carbon Reduction Potential of Construction Waste Recycling and Spatial-Temporal Heterogeneity of Influencing Factors
The resource utilization of construction waste is a key area for synergistic efficiency reduction and carbon reduction.Based on the calculation of carbon reduction potential of construction waste in China from 2006 to 2021,exploratory spatial analysis and geographically weighted regression model were used to study the spatial-temporal characteristics,spatial correlation,and spatial-temporal heterogeneity of carbon reduction potential of construction waste.The results show that there are significant spatial differences in the carbon reduction potential of construction waste,presenting a clear spatial clustering pattern in China.the carbon reduction potential of construction waste in China has an overall pattern of"high in the east and low in the west"and"high in the south and low in the north"..The R2 values of the GWR model are higher than those of the OLS model,and the GWR model can better explain the impact mechanism of carbon reduction potential of construction waste.The regression results of GWR indicate significant spatial-temporal heterogeneity of the influencing factors of carbon reduction potential.
