大南昌都市圈土地利用碳排放与新型城镇化的异质性特征及影响强度分析
The analysis of heterogeneity characteristics and influence intensity between land use carbon emissions and new-type urbanization in Nanchang metropolitan area
摘要
Abstract
It is an urgent need to explore the spatiotemporal differences in land use carbon emissions and new-type urbanization level and their interaction relations in metropolitan areas,which is of great significance for reducing the pressure of carbon emission reduction and realizing the"dual-carbon"goal as scheduled in China.Taking Nanchang metropolitan area as the study area,the emission coefficient method,Theil coefficient method and geographical detector model were used to explore the spatiotemporal differences,regional differences and influence degree between land use carbon emissions and new-type urbanization level.The research results showed that the growth of land use carbon emissions in the study area gradually slowed down,while the carbon emissions in the central economically developed areas were larger.While the new-type urbanization level increased steadily,and the overall gap decreased year by year.The impacts of different new-type urbanization factors on the spatial differentiation of land use carbon emissions varied greatly.The effects of land use efficiency and population urbanization level on the spatial differentiation of land use carbon emissions continued to increase,while the effects of economic development level gradually weakened.The combined effects of the new-type urbanization factors were nonlinear,and the combined effects of land use efficiency&economic development level and economic development level&population urbanization level have a greater impact on the spatial differentiation of land use carbon emissions.The optimization and adjustment of land use efficiency and labor flow should be focused during the process of low-carbon urbanization,and different policies and measures should be adopted according to local conditions to optimize urban construction,so that the pressure of urban carbon emission reduction will be relieve and the sustainable development of natural ecological environment and social economy will be promoted.关键词
