Study on Carbon Sequestration Rate of Vegetation Layer of Main Shrub Artificial Forests in Guyang County of Inner Mongolia
In order to investigate the carbon sequestration rate of vegetation layer of different shrub artificial forests in Guyang County of Inner Mongolia,three common shrub artificial forest tree species(Caragana korshinskii,Hip-pophae rhamnoides,and Prunus sibirica)were selected as the research object.Through on-site standard wood sam-pling,biomass models of each tree species were established,and the method of space replacing time was used to measure the carbon content of three common shrub forest tree species in the study area.The carbon density and car-bon sequestration rate of different shrub tree species were analyzed and estimated.The results showed as follows:the carbon sequestration rate of the vegetation layer in the artificial forests of three different shrubs and different for-est ages in Guyang area ranged from 0.12 t·hm-2a-1 to 1.0 t·hm-2·a-1,with the carbon sequestration rate of the vegetation layer in the artificial forests of Caragana korshinskii ranging from 0.12 t·hm-2·a-1 to 0.38 t·hm-2·a-1,the carbon sequestration rate of the vegetation layer in the artificial forests of Hippophae rhamnoides ranging from 0.12 t·hm-2·a-1 to 1.0 t·hm-2 ea-1,and the carbon sequestration rate of the vegetation layer in the artificial forests of Prunus sibirica ranging from 0.22 t·hm-2·a-1 to 0.68 t·hm-2·a-1.
