武汉城市圈土地利用碳排放时空演变及驱动因素
Spatial and Temporal Evolution of Land Use Carbon Emissions and Analysis of Driving Factors in Wuhan Metropolitan Area
摘要
Abstract
[Objective]The concentration of industries and increase in population cause large resource consumption and high carbon emissions.The research on carbon emission at metropolitan area can provide reference for carbon emission reduction policies and methods.[Methods]The spatiotemporal evolution of land use carbon sources/carbon sinks in the three periods of Wuhan metropolitan area(2000,2010,and 2020)was explored through establishing the carbon emission estimation model and spatial-temporal geographic weighted regression model based on remote sensing image data and economic and social data.[Results](1)The carbon emissions in Wuhan metropolitan area increased from 31,296,900 tons in 2000 to 145,905,100 tons in 2020,with an average annual growth rate of 8.45％.(2)The main influencing factors of carbon emissions in the Wuhan metropolitan area were industrial structure,technology level,and the proportion of construc-tion land.(3)The influencing factors of carbon emissions in Wuhan metropolitan area showed an obvious spatial heterogeneity,and the impact of various factors on carbon emissions varied widely across regions.[Conclusion]Carbon emissions in urban areas have significant spatial and temporal heterogeneity,and the level of resources and focus of development varies greatly from city to city,which lead to changes in carbon emission levels.When formulating regional carbon emission reduction policies and allocating carbon emission reduction tasks,factors such as the economic level and industrial structure of each region should be fully considered.关键词
