Study on Forest Carbon Storage Based on the Fifth Forest Resource Census Data in Hubei Province
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 potential at regional scale.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 32.51 Mg C/hm2,the total carbon 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 natural forest 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 will be conducive to the rapid improvement of the carbon density and carbon storage level of forest vegetation.
