| Abstract: |
| To understand the carbon sink function of public welfare forest in Guangdong province, this paper takes 25 demonstration areas of public welfare forest in Guangdong province from 2021 to 2023 as the research objects, measures the carbon sink capacity of the demonstration areas based on the data from the Second
-Class Survey Forest Resources Inventory, and analyzes the differences of carbon storage and carbon density in
different regions, forest age classes, and forest types. The results indicate that the carbon storage of 25 demonstration areas of public welfare forest in Guangdong province was 269. 69×10
4
t, most of which were concentrated in northern Guangdong, mainly middle-aged forest and broad-leaved mixed forest, accounting for 42. 6%
and 70. 1%, respectively. The average carbon density was 53. 23 t·hm
-2
, and the carbon density of near-mature forest and over-mature forest was 105. 8 times that of Litchi chinensis (Dimocarpus longan). The young
and middle-aged forests account for about 64. 66% of the forest area of 25 demonstration areas of public welfare
forest. As the demonstration areas of public welfare forest continue to promote key forestry ecological engineering afforestation and comprehensively improve the level of forest management, the demonstration area will continue to play a significant role in carbon sink function. |
