湖南省森林生态系统碳储量、碳密度及其空间分布
Carbon storage, carbon density and spatial distribution of forest ecosystems in Hunan Province
摘要
Abstract
Based on the field investigation and forest resource inventory in 2014,we estimated carbon density,carbon storage and their spatial distribution of forest ecosystems in Hunan Province.The results showed that the average carbon density of forest ecosystems in Hunan Province was 130.69 t · hm-2,of which 28.36,1.77,0.90,1.36 and 98.30 t · hm-2 were in trees,shrubs,herbs,litter,and soil,respectively.Carbon density of vegetation layer and litter layer were positively correlated with that of soil,and the carbon densities of different forest types were found in the following decreasing sequence:broad-leaved forest (175.26 t · hm-2) ＞ Chinese fir forest (136.81 t · hm-2) ＞ masson pine forest (133.84 t · hm-2) ＞ Cupressus funebris forest (124.88 t · hm-2) ＞ bamboo forest (117.29 t · hm-2) ＞ poplar forest (95.08 t · hm-2) ＞ economic forest (80.94 t · hm-2) ＞ slash pine plantation (64.71 t · hm-2) ＞ shrub (63.73 t · hm-2).The total carbon storage was 1572.02 Tg C in the forest ecosystems in Hunan Province,of which 341.18,21.29,10.78,16.36,1182.38 Tg C were in trees,shrubs,herbs,litter,and soil,respectively.The carbon storages of different forest types were found in the following decreasing sequence:broad-leaved forest (545.77 Tg C) ＞ Chinese fir forest (419.91 Tg C) ＞ masson pine forest (275.58 Tg C) ＞ bamboo forest (127.76 Tg C) ＞ shrub (74.44 Tg C) ＞ economic forest (71.25 Tg C) ＞ Cupressusfunebris forest (25.81 Tg C) ＞ slash pine plantation (22.39 Tg C) ＞ poplar forest (9.11 Tg C).Among 14 cities at prefecture scale,the highest carbon storage (267.43 Tg C) in the forest ecosystem was found in Huaihua,while the lowest (28.12 Tg C) was found in Xiangtan.Spatial distribution of carbon storage was ranked as the order of southwestern Hunan ＞ southern Hunan ＞ northern Hunan ＞ central Hunan.Broad-leaved forest,Chinese fir forest,and masson pine forest acted as the main contributor in carbon storage of the forest ecosystems in Hunan Province,accounting for 34.72％,26.71％,and 17.53％,respectively.关键词
