摘　　要：基于森林资源清查资料,结合实地调查校正,估算了浙江安吉县森林的碳储量。结果表明:安吉县森林植被的总碳储量为3.91TgC,平均碳密度为21.02tC·hm^(-2);不同的植被类型当中,碳储量最大的为毛竹林,占植被总碳储量的57.3%,其次为马尾松林,占到了7.9%。竹林和马尾松、经济林和硬阔林的碳汇能力在安吉县占据着主导性作用;安吉县幼龄林、中龄林和近熟林的面积分别占林分总面积的57.94%、26.33%和12.10%,加起来总和占到96.37%,全县森林植被碳储量将处于持续增长中,随着林龄的增大,森林植被碳密度将逐步增大;天然林的碳贮量是人工林的7倍之多,占绝对优势。以中龄林为主要碳贮区的碳汇潜力巨大,减少人类活动对天然森林的破坏及采取森林分区经营管理是稳定和增强安吉森林碳汇功能的有效途径。According to the calculation method and forest inventory data of forest carbon storage,combined with field survey correction,forest carbon reserves in Anji County of Zhejiang were estimated. The results showed that forest vegetation carbon storage in Anji was 3.91 TgC,the average carbon density was 21.02 tC/hm^2. Among different vegetation types, the largest carbon reserves were found in Mao Zhulin, accounted for 57.3% of the total. Bamboo,masson pine,non-timber forest and hardwood forest played leading role in the carbon sink capacity in Anti. The areas of young forest, middle age forest and near mature forest accounted for 96.37% of the total,indicating that the forest vegetation carbon storage in Anji was in its increasing stage. With the increase of forest age, the forest vegetation carbon density would gradually increase. The carbon storage of natural forest was 7 times more than that of artificial plantation, which was in dominant status. Middle age forests presented great potential for carbon sequestration. It was suggested that the effective ways to stabilize and increase forest carbon sink in Anti were to reduce human activities on the destruction of natural forests and to enhance the regional forest management.
