Scientific estimation of carbon storage and carbon density of forest vegetation in Hubei Province , which can provide scientific basis for studying forest carbon sink and carbon potentialat regionalscale . Based on the data of the fifth forest resource census in Hubei Province , the biomass conversion factor method and carbon content of different tree spe- cies were used to analyze the carbon storage distribution characteristics of different land classes , dominant tree species and age groups in the arbor forest in Hubei Province . The results showed that the average carbon density of forest vegetation layer in Hubei Province was 32. 51Mg C/hm2 , the totalcarbon storage was 2. 62×108 t , and the carbon density of differ- ent land types was ranked as tree forest>bamboo forest>woodland>shrub forest. The carbon density and carbon storage of naturalforest were significantly higher than that of plantation forest. With the increase of forest age , the forest carbon storage gradually increased , and the carbon storage of middle-aged and young forests accounted for 83. 59% of the total forest carbon storage in the province . The forest vegetation carbon storage in Hubei Province is mainly distributed in the mountainous areas of northwest Hubei , southwest Hubei and east Hubei , the priority to improve the forest quality in this region willbe conducive to the rapid improvement of the carbon density and carbon storage levelof forest vegetation .
