摘　　要：广西是我国重要的矿产基地,面临着严重的矿区生态环境问题。本研究采用固碳速率法和市场价值法核算广西矿区固碳量和固碳经济价值。研究发现,广西整体的固碳量为1.19×10^(8) t·CO_(2)/a,固碳经济价值为6.53×109元,约占广西2021年GDP的0.264%;进一步剖析矿区的空间分布,发现崇左市、百色市、梧州市的固碳量和固碳经济价值排名前三,其中崇左市和百色市的固碳经济价值对GDP贡献超过1个百分点。结合测算结果,提出以下政策建议:(1)加强固碳工作的组织领导和监督考核;(2)加强废弃矿区生态修复;(3)完善碳交易市场的机制体制。Guangxi Province is an important mineral base in China,which is facing serious ecological and environmental problems in mining areas.This study uses the carbon-fixing rate method and the market value method to calculate the carbon sequestration amount and economic value of the mining area in Guangxi Province.The study finds that the overall carbon sequestration amount of Guangxi Province is 1.19×10^(8) t·CO_(2)/a,the economic value of carbon sequestration is 6.53×109 RMB,accounting for about 0.264%of Guangxi Province s GDP in 2021.Further analysis of the spatial distribution of the mining area finds that Chongzuo City,Baise City,and Wuzhou City ranked the top three in carbon sequestration and economic value,among which Chongzuo City and Baise City have a contribution of more than one percentage point to GDP from carbon sequestration value.Based on the calculation results,some policy suggestions are proposed at the end of the study:(1)To strengthen the organization,leadership and supervision of carbon sequestration work;(2)To enhance the ecological restoration of abandoned mines;(3)Improve the mechanism and system of carbon trading market.
