Abstract:: In order to promote the carbon sequestration of urban forest and enhance the function and value of urban forest ecosystem, based on the second-class survey data of forest resources in the city-encircling forest belt of Wuhan in 2008 and 2018, the biomass continuous expansion factor method and carbon coefficient method were adopted to estimate the forest carbon storage and carbon density of the city-encircling forest belt, and its changes in decade were compared. The results showed that:(1)the carbon storage and carbon density had increased significantly in the past 10 years; the carbon storage and carbon density in the city-encircling forest belt had increased from 64 692.413 3 t and 27.389 7 t/hm² to 119 789.961 3 t and 47.243 4 t/hm², respectively; by 2018, the theoretical value of forest carbon storage in the city-encircling forest belt was about 9.878 5 million yuan;(2)by 2018, the section with the largest forest carbon storage was the Jiangxia District, but the carbon storage difference between the sections was narrowing; the section with the highest carbon density had changed from the Dongxi Lake District to the Caidian District;(3)the forest carbon storage showed a trend of gathering to a few community types; by 2018, camphor forest had become the community type with the largest carbon storage in the city-encircling forest belt;(4)the carbon storage and carbon density of near-mature and mature forests increased significantly, but young forests were still most of the carbon storage in city-encircling forest belt. The forest carbon storage in the city-encircling forest belt had great potential for increasing carbon storage, but accurate forest tending should be carried out in time to ensure the effective release of carbon storage potential and promote the structural balance of carbon storage.
