Stock and Distribution of Carbon in Acacia cincinnata Plantation
摘要
Abstract
Carbon stock and the distribution of an 8-year-old Acacia cincinnata plantation in Nanning,Guangxi,China,were investigated based on field sampling data.The results showed that carbon content in different organs of A.cincinnata ranged from 465.8 to 508.2 g · kg-1,and it was distributed in a descending order as follows:stem ＞ leaf ＞ branch ＞ root ＞ bark.Carbon content in the soil (0-80 cm) was 8.44 g · kg-1 which declined with soil depth.The carbon stock in A.cincinnata plantation ecosystems was 126.07 t · hm-2,which distributed among the tree layer with a stock of 28.76 t · hm-2,shrub layer 5.35 t · hm-2,herbaceous layer 1.25 t · hm-2,litters 1.69 t · hm-2,and the soil layer (0-80 cm)89.02 t · hm-2.Annual net productivity ofA.cincinnata plantation was 10.15 t · hm-2 · a-1 and annual carbon storage was up to 5.64 t · hm-2 · a-1.关键词
