Abstract

Abstract: The carbon storage, carbon density and carbon sink of the dominant tree species and age group in the public welfare forest arbor layer were studied in Shaoguan city. The results showed that the carbon storage of Shaoguan public welfare forest arbor was 190.06 Tg, and the dominant tree species for total carbon sequestration were broad-leaved. The average carbon density was 34.73 t·hm–2, and the carbon density of tree species generally increased with the increase of age group; the carbon sink of public welfare forest arbor was 239 000 t·a–1, it was mainly carbon sink of young and middle-aged forests. Increasing the stock volume per unit area of broad-leaved forests and young and middle-aged tree species was the main way to increase the organic carbon storage and carbon sink function of public welfare forests.

Key words: public welfare forest, carbon storage, carbon density, carbon sink, dominant tree species, forest age

摘要： 对韶关市公益林乔木层的优势树种和龄组的碳储量、碳密度和碳汇量进行分析。结果表明，韶关公益林乔木林碳储量为190.06 Tg，固碳总量优势树种以阔叶林为主，龄组以中幼林为主；平均碳密度为34.73 t·hm–2，随着龄组增加，树种的碳密度普遍呈增加趋势；公益林乔木林碳汇量为 23.90 万t·a–1，以中幼林的碳汇为主。提高阔叶林和中幼龄树种的单位面积蓄积量，是增加公益林有机碳储量和碳汇功能的主要途径。
