Analysis about characteristic of carbon storage and carbon density of arbor in Liuyang city
By using forest resource survey data of Liuyang(2012), the biomass and carbon storage of arbor in Liuyang were estimated with the method of regression equation between biomass and volume in different forest types,calculated and analyzed the carbon storage and carbon density of different sorts of forestand different age-structure and the carbon distribution between plantations and natural forests.The results show that: (1)The carbon storage of Liuyang’s arbor totaled 4 115 652.91 t, average carbon density is 17.10 t/hm2; (2)Carbon storage from big to small in different sorts of forest is timber forest> shelter forest>special using forest>economic forest,special using forest have the highest carbon density(26.99 t/hm2), Other broad-leaves trees have the biggest carbon storage, the proportion is as high as 41.83%,then followed by Cunninghamia Lanceolata forest; (3)The basic regularity on carbon density of different age is half-mature forest> near-mature forest> mature forest> young forest> over ripeness forest. Plantation and natural forest carbon storage in Liuyang city were similar, Natural forest is higher than plantation forest in the aspect of carbon density.
