摘要:2005 年12 月初, 对浙江省富阳市7 种不同土地利用类型残体现存有机碳的储量进行了研究。研究表明:①地上部分细残体有机碳储量以杉木Cunninghamia lanceolata 林最多,其次是粗放经营毛竹Phyllostachys pubescens 林、马尾松Pinus massoniana 林、次生林、灌木林和毛竹集约经营林, 农耕地最小;并且以叶片的有机碳储量为主, 其次是枝条和腐解物, 草本植物茎叶和花果树皮等储量均不超过10 %;几种土地利用类型下, 地上部分粗残体的有机碳储量均比较小。②7 种土地利用类型下, 地下部分细残体有机碳的储量均很接近, 且小于2 mm 的细残体有机碳储量均在50 %以上;毛竹林地下粗残体的有机碳储量要比其他几种类型的要高, 次生林、杉木林和马尾松林和灌木林地下部分粗残体有机碳储量非常接近。③7 种土地利用类型下, 以毛竹粗放经营竹林和杉木林的残体有机碳储量为最大, 分别达到了3.20 和3.19 thm-2 , 是农耕地残体有机碳储量的3.4 倍;次生林、马尾松林和集约经营的竹林残体有机碳储量为2.7 ～ 1.6 thm-2 , 也分别比农耕地残体有机碳储量高;农耕地的残体有机碳储量最低, 只有0.94 thm-2 ;不同土地利用类型残体有机碳储量由高到低的顺序为:粗放经营毛竹林杉木林马尾松林次生林集约经营毛竹林灌木林和农耕地。表6 参19

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 .
