The Carbon Storage of Forest Debris among Different Land-Use Types in North Subtropical Areas in China

Abstract

This study considered organic carbon storage in fine forest debris( extensively managed bamboo > masson pine > natural secondary forest > shrubs > intensively managed bamboo > agricultural cropped land. Organic carbon of fine forest debris was mainly stored in the leaves, followed by the branches, and then the decomposed debris, while the percentage of the amount in the dead herb was less than 10％. In addition, (2)the underground carbon storage in fine debris, of which the amount in different vegetation types was similar, accounted for more than 50％ of the total carbon storage. Meanwhile, as to the coarse debris, underground carbon storage in both bamboo stands was higher (P Chinese fir > masson pine > natural secondary forest> intensively managed bamboo > shrubs > agricultural cropped land.
