摘　　要：以广东省1979—2012年森林资源连续清查数据为基础,结合广东省当地分树种生物量扩展因子方程,对广东省近30 a的森林碳储量和碳密度进行估算。结果表明:广东省森林碳储量从1979年的2.766 47×10~7t增加到2012年的1.673 778×10~8t,年均增加4.366×10~6t,年变化率5.45%;平均碳密度从7.57 t/hm^2增加到23.01 t/hm^2。乔木林对森林碳储量的贡献占据主导地位,其中阔叶林贡献比较突出,且增长较快;在林龄结构上,幼龄林和中龄林面积和碳储量都占有较大比例。According to the national forest inventory data collected in Guangdong Province since 1979 to 2012 and the regional and tress species dependent biomass conversion equations, we estimated forest carbon storage and density. The total carbon storage of forests in Guangdong Province was increased continuously from 2.766 47× 10^7 tol.673 778× 10^8t, and the annual variability was 5.45%, with an annual increment of 4.366×10^6t. The carbon density was increased from 7.57 to 23.01 t/ hm2. Arbor forest, especially broad-leaved forest played a dominant role, which contributed most to the total forest carbon storage. In terms of age structure, young forests and mid-aged forests occupied a large proportion in area and carbon star-age.
