Study on Forest Carbon Storage and Carbon Density in Hefei City
摘要
Abstract
Use the seventh forest resource inventory data,based on the established regression equation between forest volumes and biomass for the different forest types,the forest area,volumes,biamoss,carbon storage and carbon density were estimated in Hefei.The results showed that forest was mainly distributed in three county(Feixi county,Feidong county and Changfeng county),with large proportion of young and middle age.The forest areas were 47 983.4 hm^2,forest volumes were 523 239 m3,forest biamass were 231 260.87 t,forest carbon stocks were 115 630.43 t and forest carbon density was 2.41 t/hm^2.The area of Populus L.and the biomass,volume and carbon storage of Pinus massoniana were the biggest.The young forest area was the biggest,as the age increased the forest area decreased.The volumes,biomass and carbon storage of middle-aged forest were the greatest,and increased firstly with increasing age and then decreased.The carbon density of near-mature forest was the highest,reaches 12.45 t/hm^2,but the carbon density of young forest was only 0.32 t/hm^2.The carbon density of Populus L.in its life was relative bigger,which was beneficial to carbon storage,but the carbon stock was smaller because the age was young and the rotation was short.Therefore,the focus on strengthening the tending and management of existing forests,selecting adapated tree in a long time was need to society sustainable development.关键词
