基于土地利用变化的江苏省碳排放时空差异与碳平衡分区
Spatial-temporal differences of carbon emissions and carbon balance zoning in Jiangsu based on land use change
摘要
Abstract
With a case study of 13 cities divided into districts in Jiangsu,China,the CE,carbon absorption and carbon compensation rate were calculated and analyzed based on the(CE)and carbon sequestration estimation methods.Subsequently,the Environmental Gini Coefficient(EGC)was utilized to evaluate the spatial carbon balance characteristics from the economic and ecological perspectives.The results showed that from 2005 to 2020,the CE of LULC in Jiangsu increased from 1421,000,500 tons to 230,153,250 tons,and the carbon absorption fluctuated from 30,393,830 tons to 36,287,030 tons,indicating that Jiangsu Province is the overall carbon source.The carbon emissions and economic development level are in a relatively coordinated state,and the coordination with population aggregation is relatively high.Based on carbon balance analysis,the 13 districts are divided into five types:carbon sink function area,low-carbon conservation area,economic development area,carbon intensity control area,and high-carbon optimization area.It is recommended that the first two zones give full play to ecological advantages and focus on promoting the realization of ecological product value.Other zones should prioritize promoting the low-carbon transformation of industries and the green development of energy.关键词
