根据湖南省森林资源二类调查数据,运用生物量清单法和平均生物量法,对湖南省森林植被碳储量分乔木林碳库、竹林碳库、经济林碳库和灌木林碳库4大碳库分别进行估算并分析其空间格局的差异与特征。结果表明：湖南省2016年森林植被碳储量为253.359 TgC,平均碳密度为24.266 t/hm^2。全省14个市州中,怀化市的森林植被碳储量最大,为36.863 TgC,其次是邵阳市、永州市和郴州市,常德市的森林植被碳密度最高,为40.584 t/hm^2;不同森林植被类型中,阔叶树碳储量最大,三杉碳密度最高。

英文摘要：

Basing on the forest resource inventory of Hunan Province, we estimated the forest vegetation carbon storage by biomass inventory method and average biomass method. Furthermore, we analyzed differences and characteristics of the carbon storage spatial pattern. In the present work, the forest vegetation carbon storage of Hunan was divided into four carbon pools, they were high-forest carbon pool, bamboo-forest carbon pool, economic-forest carbon pool and shrub- forest carbon pool. The high-forest carbon pool was estimated by biomass inventory method, carbon pools of economic- forest, shrub-forest and bamboo-forest were estimated by average biomass method. It was shown by the results that carbon storage and carbon density of Hunan forest vegetation in 2016 was 253.359 TgC and 24.266 t/hm2 respectively. Among the 14 states in Hunan, the forest vegetation carbon storage of Huaihua City was the largest with the value of 36.863 TgC, followed by Shaoyang City, Yongzhou City and Chenzhou City. Meanwhile, the forest carbon density of Changde City was the highest with the value of 40.584 t/hm2. Among the 11 forest vegetation types, the forest carbon storage of broad-leaved tree was the largest, while the forest carbon density of mixed taxodiaceae {Metasequoia glyptostroboides, Taxodiumascenden, Taxodiumdistichum （L.） Rich, and Glyptostrobuspensilis） was the highest.
