摘要
文章基于岳阳市2009年森林资源统计数据,对全市森林植被类型的生物量、碳贮量和碳密度进行初步估算。结果表明:岳阳市森林植被碳贮量为9.238Tg,其中,平江县的森林植被C贮量最大,为3.606Tg,占总C贮量的39.03%。各森林类型的C贮量来看,松木林的C贮量最大,为2.754Tg,占总C贮量的29.81%。岳阳市森林植被平均C密度为16.02t.hm-2,各县市区森林植被的C密度为13.39～27.10t.hm-2,森林植被平均C密度最大是云溪区,为29.02t.hm-2,各森林类型中阔叶树的C密度最大,为27.24t.hm-2,是全市森林植被平均C密度的近2倍。
An estimation of total biomass, carbon storage and carbon intensity of all types of forest vegetation in the city was carried out based on the statistics of 2009 forest resource inventory. Results indicated that the total carbon storage of Yueyang Municipality was 9.238 Tg, of which the largest was found in Pingjiang County, with an amount of 3.66 Tg, accounting for 39.03% of the total carbon storage of the municipality. Among the carbon storages of different types of forests, the largest was in pine forests, with an amount of 2.754 Tg, accounting for 29.81% of the total storage. The average carbon intensity of forest vegetation in the municipality was 16.02 t/ha, and the averages of counties were between 13.39-27.10 t/ha, with the largest （29.02 t/ha） in Yunxi District. Among the carbon intensity of different forest types, the largest was found in broadleaved forest, with an amount of 27.24 t/ha, nearly 2 times of the average of the municipality .
