在陆地生态系统中,森林生态系统是最大的碳库,其碳贮量约为1146PgC(PgC指1米深度的土壤有机碳总质量,1pg=109t),占全球陆地总碳贮量的46%。
In terrestrial ecosystems, forest ecosystems are the largest carbon stocks with a carbon storage of about 1146 PgC (PgC is the total mass of soil organic carbon at 1 m depth, 1 pg = 109 t), accounting for 46% of the total terrestrial carbon storage in the world .
