Spatial and Temporal Change of Carbon Fixation and Carbon Emission in Jiangxi Province from 2000 to 2022
Exploring the spatial and space law of carbon fixation and carbon emission in Jiangxi province and grasping its carbon balance situation will help the province to explore a feasible path of energy conservation,emission reduction and energy exchange increase.Based on natural and socioeconomic data,the hotspot analysis method,multiscale geographically weighted regression(MGWR)model and local binary relationship were used to analyze the spatial and temporal distribution rules of carbon fixation and carbon emission in Jiangxi province from 2000 to 2022.The results show that between 2000 and 2022.The carbon fixed value of Jiangxi province presents a spatial distribution pattern of low center and high periphery,opposite,carbon emissions show a distribution pattern of high center and low around.The results of MGWR showed that,in 2000,a significant negative correlation between temperature,GDP,Tiav and POP and carbon fixation,precipitation and Fiav showed a positive correlation with carbon fixation.But by 2022,Tiav and carbon fixation shifted from a negative to a significant positive correlation.The relationship between Fiav and carbon fixation changed from positive correlation to significant negative correlation.From 2000 to 2022,there were four relationships:negative linear correlation,convex shape,unclear and insignificant relationship between carbon fixation and carbon emission in Jiangxi province.The results highlight the dual impact of ecological restoration and economic structure transformation on carbon fixation and carbon emission,and provide an important basis for formulating effective emission reduction policies and sustainable development strategies in Jiangxi province.
