| 摘 要： | 该研究采用材积源生物量法及广东省1994—2003年森林资源档案数据，量化10年间森林植被恢复过程中碳储量动态变化.其中OBPA是指疏林、竹林、经济林和四旁林.研究结果如下: 1994—2003年广东省森林植被共固定碳41.67 Tg，碳密度增加了1.58 Mg/hm2；林下层和凋落物层碳储量占总碳库的38%～44%，凋落物层碳储量略大于林下层；不同类型森林的碳储量排列如下:针叶林阔叶林OBPA针阔叶混交林；马尾松林碳储量在11种林型中最大，南洋楹林最小；10年中近熟林、成熟林、过熟林碳储量皆有增长，幼龄林碳储量大幅度减少，中龄林碳储量小幅度波动，其碳储量始终高于其他4个龄级；阔叶林固碳率大于针叶林和针阔叶混交林，10年间的波动范围是0.19～1.36 Mg/(hm2·a).

| Abstract: | The study was carried out using volume derived method and forest resource inventory from 1994 to 2003 of Guangdong Province. The authors quantified the carbon accumulation of forest vegetation in the process of forest restoration during the 10 years. OBPA included open forest, bamboo forest, production forest and ambient trees in this paper. Results were as the followings: the whole forest vegetation had accumulated carbon 41.67 Tg during this period. Forest carbon density increased by 1.58 Mg/hm2 at the same time. Carbon storage of litterfall and understory occupied 38%-44% of the total carbon pool. Carbon storage of litterfall was a little more than that of understory. The result of comparing four carbon pools is as followings: coniferous forests>broadleaved forests>OBPA>mixed forests. Carbon storage of P. massoniana forests was the biggest among the 11 forest types and Albizia falcataria (Linn.) Fosberg forest was the smallest. Carbon storage of maturescent forest, mature forest and post mature forest increased but young forest diminished. Carbon storage of middle-aged-forest had little changes and it was always the biggest among the five groups. Carbon accumulation rate of broadleaved forests was the highest among broadleaved forests, coniferous forests and mixed forests in Guangdong Province, with the rate ranging from 0.19 to 1.36 Mg/(hm2·a) during this period. |
