【摘要】 利用标准样方法研究了孝顺竹林生态系统碳含量、碳储量及其空其间分配格局。结果表明:孝顺竹林乔木层各器官碳含量介于0.4893 g.g-1~0.5222 g.g-1之间,从高到低排序依次为竹秆(0.5222 g.g-1)>竹根(0.5177 g.g-1)>竹蔸(0.5041 g.g-1)>竹叶(0.4967 g.g-1)>竹枝(0.4893 g.g-1);土壤层碳含量随深度增加而降低,0~20 cm为0.0104 g.g-1,20 cm~40 cm为0.0046 g.g-1;生态系统各组分碳含量表现为乔木层(0.5148 g.g-1)>枯落物层(0.4837 g.g-1)>土壤层(0.0076 g.g-1);孝顺竹林生态系统碳储量为44.8599 t.hm-2,空间分布序列为土壤层(41.2518 t.hm-2)>乔木层(3.5965 t.hm-2)>枯落物层(0.0116 t.hm-2),分别占91.95%,8.02%和0.03%。更多还原

【Abstract】 Carbon content,storage and spatial distribution patterns of Bumbusa multiplex forest ecosystem were measured by means of sample plot methods.The result showed that the carbon content in different organs of the arber layer ranged from 0.4893 to 0.5222 g·g-1,which was in order as follows:trunk(0.5222 g·g-1)> root(0.5177 g·g-1)> underground truck(0.5041 g·g-1) > leaf(0.9647 g·g-1)> branch(0.4893 g·g-1).The soil organic carbon content decreased with the increase of soil depth,respectively being 0.0104 g·g-1(0～20 cm) and 0.0046 g·g-1(20 cm～40 cm).The component of Bumbusa multiplex forest ecosystem carbon content ranked as follows:the arber layer(0.5148 g·g-1) > litter layer(0.4837 g·g-1) > the soil layer(0.0076 g·g-1).The carbon storage of Bumbusa multiplex forest ecosystem was 44.8599 t·hm-2,spatial distributions sequence was the soil layer(41.2518 t·hm-2) > the arber layer(3.5965 t·hm-2) > litter layer(0.0116 t·hm-2),accounting for 91.95%,8.02% and 0.03% respectively.更多还原
