碳生态补偿是对碳汇区域付出碳汇成本和牺牲发展机会的经济补偿,差异化精准各县(市、区)之间碳生态补偿,对各省市在"双碳"目标下,促进碳减排,实现区域发展的均衡化、可持续化具有重要意义.该文基于石家庄市2010、2015、2020年土地利用分类结果,运用遥感解译和碳排放系数法测算各年份碳排放,并对2020年石家庄20个县(市、区)的碳生态补偿分区分级.结果表明:(1)研究区碳排放时间上先升后降,空间上在2010年呈南北低中心高分布,在2015、2020年呈中部高于南北,北部高于南部的特点.(2)2020年灵寿县、桥西区等中心城区为碳生态补偿支付区,且中心城区南部等级高于北部;平山县、井陉县等外围县区为碳生态补偿受偿区,且西部等级高于东部.(3)管理类型级别中严格管控区分布在东部平原县域及中心城区,西部山区县域多为轻松管控区.
Analysis on Characteristic of County Scale Carbon Emission and Carbon Offset Zoning and Grading
Carbon ecological compensation involves providing economic compensation for the carbon sink region,covering the cost of carbon sequestration and forgoing development opportunities.Tailored and precise carbon ecological compensation among different counties(cities,districts)is of significant importance for provincial and municipal efforts to promote carbon reduction and achieve balanced and sustainable regional development under the"dual carbon"goals.Based on the land use classification results of Shijiazhuang in 2010,2015 and 2020,carbon emissions were measured by remote sensing interpreta-tion and carbon emission coefficient method,and carbon ecological compensation in 2020 from 20 counties(cities and districts)of Shijiazhuang area was divided into zones and grades.The results indicated carbon emissions in the study area in-creased and then decreased over time,with a spatial distribution characterized by"low in the north and south parts and high in the center"in 2010,while in 2015 and 2020,it showed a pattern of"higher in the center than in the north and south,and higher in the north than in the south".In the year 2020,regions such as Lingshou County and Qiaoxi District and in the central urban areas have been designated as carbon ecological compensation payment zones,and the southern parts of these central areas possessing a higher status than the northern.Peripheral counties like Pingshan County and Jingxing County are deemed as carbon ecological compensation beneficiary zones,and the western regions holding superiority over the eastern.In terms of management types and levels,the eastern plains and central urban areas are subject to strict control,whereas the western moun-tainous counties are largely classified under a relaxed control regime.
