摘要
基于2010—2020年土地利用数据、经济增长数据和能源消费数据,采用碳排放系数法和Tapio脱钩模型计算了广西北部湾经济区净碳排放总量,分析了与经济增长的脱钩关系。研究表明,广西北部湾经济区土地利用净碳排放量呈不断增长趋势,净碳排放量和碳排放强度总体呈东北高西南低的空间分布特征;与经济增长的关系在2015年和2020年处于扩张性负脱钩状态,其余年份处于弱脱钩状态,总体脱钩状态良好。
Based on the land-use data,economic development data and energy consumption data from 2010 to 2020,we used the carbon emission coefficient method and the Tapio decoupling model to calculate the total net carbon emission of the Guangxi Beibu Gulf Economic Zone and analyze the decoupling relationship with economic development.The research result shows that the net land-use carbon emission of the Guangxi Beibu Gulf Economic Zone is on the rise,the net carbon emission and carbon emission intensity generally show the spatial distribution characteristics of high in the northeast and low in the southwest.Land-use carbon emission and economic development are in an expansionary negative decoupling state in 2015 and 2020,in a weak decoupling state in the rest of the years,and the overall decoupling state is good.
