皖南山区森林碳储量及其动态变化
Forest carbon storage and dynamic change in the mountain region of southern Anhui
摘要
Abstract
Based on data from the 7th,8th and 9th Chinese continuous national forest inventory in Anhui Province, forest carbon storage and dynamic change in the mountain region of southern Anhui were estimated with variable biomass expansion factor function (BEFF) method. The result showed that the total forest carbon storage in the mountain region of southern Anhui was increased continuously from 4 491.01×104t in 2004 to 6 223.13×104t in 2014,and the annual average increment was 173.21×104t,with the annual average increment rate 3.86%. Arbor forest played the leading role in the forest carbon storage,with a continuously increased proportion,from 74.99% in 2004 to 79.85% in 2014. The middle aged forest played a dominant role in carbon storage and area in the arbor forest. The carbon storage and density of young forest, middle age forest and mature forest was increased, with the decreased area of middle aged forest and increased of young forest and mature forest.The carbon density of eight main species played a increasing tendency on the whole.The area and carbon storage of Cunninghamia lanceolata,broad-leaved forest,Pinus massoniana, coniferous and broad-leaved mixed forest,Quercus spp. played an advantage role in the arbor forest,with the outstanding increment of broad-leaved forest and a little decrement of Cunninghamia lanceolata, Pinus massoniana. On the whole,the arbor forest carbon sink was still not in the high level. Therefore,it still required to take proper management measures to promote continual improving of forest quality and carbon sink level at the same time of expanding forest area in the future.关键词
