Based on the results of the national forest inventory and annual government reports,the regional distribution and assess-ment of potential forest ecosystem carbon sink from 2015 to 2020 in Fujian Province were analyzed.The results indicated that:the carbon sink capacity of Fujian's forest from 2015 to 2020 improved compared to the past 40 years;from 2015 to 2020,the carbon sink capacity of Fujian's forest ecosystem ranged from 46.9 to 21.7 million t·a-1,and the maximum value was distributed in Nan-ping.Carbon sink per area(CPA)ranged from 7.09 to 19.17 t·a-1·hm-2,and the maximum value was distributed in Fuzhou;the high values of carbon sink capacity and carbon sink per capita(CPC)were concerned in the northwest of Fujian Province,while the high values of CPA were concerned in the northeast;the total economic value of forest ecosystem carbon sink capacity in Fujian was 45.76 billion yuan·a-1,ranging from 20 to 930 million yuan·a-1 in different prefectures,and the average was 508 million yuan·a-1;the ratios of economic value of forest ecosystem carbon sink to GDP were higher in cities with lower GDP.The great regional differ-ences in potential forest ecosystem carbon sink in Fujian Province may be related to the differences in natural endowments.
