摘　　要：基于广东省2007年森林资源清查档案数据,采用材积源生物量法,量化广东省森林植被碳储量,研究广东省森林植被碳储量空间分布格局。结果表明,广东省森林植被碳储量为246.35Tg,碳密度为22.96mg·hm-2。受人为干扰和环境因素的影响,广东省森林植被碳储量在不同经济区和流域空间分布格局严重不均。就不同经济区而言,粤北及周边经济区森林植被碳储量最大,达180.22Tg;珠三角经济区次之,为34.60Tg;接着是粤西沿海经济区,为21.49Tg;粤东沿海经济区最小;仅为10.04Tg。在不同流域方面,森林植被碳储量依次为:北江流域>东江流域>西江流域>韩江流域>其他流域。广东省乔木林碳储量为202.85Tg,以中幼龄林为主,占77.1%;乔木林龄组结构与碳密度近乎成正比关系,存在较大的相关性。Based on the forest resource inventory data of 2007 in Guangdong province, the carbon storage was quantified by using volume-derived method and the spatial distribution pattern of forest vegetation carbon storage in Guangdong province was studied. The study result showed that the forest vegetation carbon storage in Guangdong province was 246.35 Tg. The forest vegetation carbon density was 22.96 mg·hm-2. The forest vegetation carbon storage in Guangdong province was unevenly distributed in different economic regions and different drainage areas resulting from the disturbance of human beings and other possible enviroments. In respect of different economic regions, the forest vegetation carbon storage in north Guangdong was the largest with a mean of 180.22 Tg , while the order of the other three economic regions was The Pearl River Delta（34.60 Tg） west Guangdong（21.49 Tg） east Guangdong（10.04 Tg）. While in respect of different drainage areas, the forest vegetation carbon storage showed the order of the Bei-jiang River basin the Dongjiang River basin the Xijiang River basin the Hanjiang River basin the other river basins. The forest carbon storage in Guangdong province was 202.85 Tg. The percentage of young and middle forest was 77.1%. The age struc-ture of forest showed direct proportion with carbon density approximately.
