Soil Organic Carbon Storage on Different Slope Positions in Cunninghamia Lanceolata Stands
摘要
Abstract
Based on the field investigation and laboratory analysis,soil organic carbon was compared between upper and lower slope positions of Cunninghamia lanceolata stands with the aim of understanding the effects of slope position on carbon fixation of Cunninghamia lanceolata stands.The results showed that organic carbon storage of litter layer were 0.9 and 1.1 t/hm2 in upper-slope and lower-slope,respectively,indicating a 32% increase from the former to the latter.Soil organic carbon storage was 149.9 and 174.2 t/hm2,respectively,in the upper-slope and lower-slope.The surface(0—40 cm) layers accounted for 55% and 56% of the total carbon storage(0—100 cm) for upper and lower slopes,respectively.Organic carbon contents decreased with increasing soil depths in both upper and lower slopes.In each layer,the content and storage of organic carbon of the upper slope were greater than those of the lower slope.关键词
