Forest Carbon Sink Measurement in the Demonstration Area of Public Welfare Forest in Guangdong Province
To understand the carbon sink function of public welfare forest in Guangdong province,this pa-per takes 25 demonstration areas of public welfare forest in Guangdong province from 2021 to 2023 as the re-search 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 demon-stration areas of public welfare forest in Guangdong province was 269.69×104 t,most of which were concentrat-ed 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-ma-ture 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 engineer-ing afforestation and comprehensively improve the level of forest management,the demonstration area will con-tinue to play a significant role in carbon sink function.
