| 摘 要： | 利用双因素方差分析法研究坡向、坡位对毛竹Phyllostachy edulis林生物量与碳储量的影响。结果表明：①坡向、坡位对毛竹生物量、竹林生态系统碳储量及其空间分配均有一定程度的影响，坡位影响比坡向更显著。具体地，坡向对植被碳储量影响显著（P＜0.05），对土壤碳储量和生态系统碳储量影响较显著（P＜0.10），坡位对植被碳储量影响极显著（P＜0.01），对土壤碳储量和生态系统碳储量影响显著（P＜0.05），但两者交互作用不显著；②不同水平上的指标均值分析显示，毛竹林生态系统碳储量阳坡大于阴坡、中下坡大于上坡。其中阳坡下坡的林分密度（3 817株·hm－2）和林分生物量（48.705 t·hm－2）均值最大，阳坡中坡的土壤有机质质量分数（22.500 g·kg－1），土壤碳储量（107.273 t·hm－2）和生态系统碳储量（156.111 t·hm－2）均值最大，平均胸径和土壤容重均值变化不明显；③在毛竹林生态系统碳储量组成方面，18个样地生态系统碳储量均值为（101.352 ± 14.980） t·hm－2（变异系数为14.78%），其中植被占20.24%，土壤占79.76%。图3表4参19

| 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. |
