Forest vegetation carbon storage, carbon density and spatial distribution pattern in 2014 in Hunan province
Regional spatial distribution pattern of carbon storage, carbon density were examined in existing forest vegetation in Hunan province of China, based on forest inventory data in 2014, biomass expansion factors (BEF) and carbon concentration of existing main forest types in this region. The result shows that:(1) carbon storage of arboreal forest vegetation was 145.23×106 tC, the highest carbon storage was found in broad-leaved forest vegetation, accounting for 47.52%, and those of the sapling forest and immature forest accounted for 69.49%of the carbon storage of arbor forest. The average carbon density of arbor vegetation was up to 16.26 tC·hm-2. (2) Carbon storage of existing forest vegetation in Hunan (2014) was 196.95×106 tC, the highest carbon storage reserves was found in the arboreal forest vegetation, accounted for 73.73%of the province’s forest vegetation. Carbon density was 16.31 tC·hm-2 in the province’s forest vegetation, and increased 1.16 tC·hm-2 by compared with 1995. (3) Spatial distribution pattern carbon storage and carbon density of the province’s forest vegetation was not consistent, the higher carbon storage was found in Huaihua and Shaoyang in the west-southern and Yongzhou and Chenzhou in the southern of Hunan province, while the higher carbon density was found in Yiyang, Changde, Shaoyang and Chenzhou. By taking closed forest protection measures to stabilize and improve the carbon storage in the high carbon storage area of forest vegetation, and increasing the zonal tree species, and optimizing the composition and structure of forest stand to improve carbon storage in the low carbon storage area of forest vegetation.
