Relationship of slope aspect and position on biomass and carbon storage in a Phyllostachys edulis stand
摘要
Abstract
The impact of slope aspect and position on biomass and carbon storage in a Phyllostachys edulis stand was tested by a two-factor analysis of variance (ANOVA). Results of the ANOVA showed: (1) no interaction between slope aspect and position. Stand carbon storage was significant for slope aspect (P <0.05) and slope position (P<0.01) with soil carbon storage and forest carbon storage significant for slope position (P< 0.05). (2) Comparisons of mean index values at different locations showed that forest carbon storage on sunny slopes was larger than on shaded slopes and greater on mid to low slopes than on upper slopes. The maximum mean stand density (3 817 tree-hm"2) and stand biomass (48.705 t-hm"2) were found on sunny, low slopes with the maximum mean soil organic matter content (22.500 g-kg"1), soil carbon storage (107.273 t-hm"2), and forest carbon storage (156.111 t-hm"2) found on sunny, mid slopes. Slope position and shading did not affect the mean diameter at breast height (DBH) or soil bulk density. (3) For spatial distribution, the mean forest carbon storage of 18 sample plots was (101.352 ± 14.980) t-hm"2 (14.78%) of which 20.24% was in the standing biomass, and the remainder was in the soil.
