Abstract

This study considered organic carbon storage in fine forest debris ( 2 , 2 -5 , 5 -10 and 10 -25 mm in diameter)and coarse forest debris ( 25 mm in diameter) of different vegetation types , namely stands of Chinese fir (Cunninghamia lanceolata), extensively managed bamboo (Phyllostachys pubescens), masson pine (Pinus massoniana), natural secondary forest (hardwood stand), and intensively managed bamboo (Phyllostachys pubescens), as well as shrub land , and agricultural cropped land , in Fuyang City , Zhejiang Province .The forest debris includes falling leaves , twiggy branches , fruits , dead herb , half-decomposed products , and decomposed debris .Results showed that (1) organic carbon storage in fine forest debris from greatest to least was Chinese fir extensively managed bamboo masson pine natural secondary forest shrubs intensively managed bamboo agricultural cropped land .Total carbon of fine forest debris was mainly stored in the leaf , followed by the branch , and then the decomposed debris , while carbon storage in the dead herb was less than 10 %.In addition , (2) the underground carbon storage in fine debris , which for the different vegetation types was similar , accounted for more than 50 % of the total carbon storage .Meanwhile , for the coarse debris, underground carbon storage in both bamboo stands was higher (P 0.05) compared to other vegetation cover types .Also , (3) carbon storage in debris of the extensively managed bamboo (3.20 thm-2)and Chinese fir (3.19 thm-2) stands was 3.4 times more than agricultural cropped land (0.94 thm-2);whereas natural secondary forest masson pine , and intensively managed bamboo stands were between 2.7 to 1.6 t hm-2 , which was also higher than that of the agricultural cropped land .Overall , carbon storage in total debris was ranked :extensively managed bamboo Chinese fir masson pine natural secondary forest intensively managed bamboo shrubs agricultural cropped land .
