贵州省土地利用碳排放与社会经济脱钩关系研究

A Study on the Relationship between Carbon Emissions of Land Use and Socio Economic Decoupling in Guizhou Province

社会经济的快速发展强烈改变了土地利用格局,进而深刻影响碳排放。选择快速发展的贵州作为研究区,基于2000-2020年土地利用和社会经济数据,利用脱钩模型,研究贵州省土地利用碳排放与社会经济之间脱钩关系。结果表明:贵州省土地利用碳排放与人均GDP之间由较理想的弱脱钩逐渐转为理想的强脱钩,土地利用碳排放与人口增长率之间由不可取的强负脱钩转为不可取的弱负脱钩,土地利用碳排放与城镇化率之间由不可取的扩张负脱钩转为较理想的弱脱钩和理想的强脱钩。

The rapid development of social economy has strongly changed the pattern of land use,and has a profound impact on carbon emissions,which is related to regional sustainable development.Based on the land use and socio-economic data from 2000 to 2020,the decoupling model was used to study the decoupling relationship between carbon emissions of land use and socio-economic in Guizhou Province.The results show that the ideal weak decoupling relationship between carbon emissions of land use and per capita GDP in Guizhou Province gradually turns to the ideal strong decoupling relationship.In Guizhou Province,the undesirable strong negative decoupling relationship between carbon emissions of land use and population growth rate changed to undesirable weak negative decoupling relationship.The relationship between carbon emissions of land use and urbanization rate in Guizhou Province has changed from undesirable negative expansion decoupling to ideal weak decoupling and ideal strong decoupling.
