摘  要:
以黑龙江塔河林业局施业区内的杜香—蒙古栎林和草类—蒙古栎林为对象,对火灾前后碳素的分布和储量进行了研究。结果表明:森林火灾发生后,蒙古栎林地上、地下部分的碳储量均表现为减少。杜香—蒙古栎林碳储量变化量为-33.812 9 t.hm-2,其中:地上部分为-0.499 4 t.hm-2,地下部分为-33.313 5 t.hm-2,贡献率分别为1.5%和98.5%;杜香—蒙古栎林碳储量变化量为-104.944 6 t.hm-2,其中:地上部分为-76.452 7 t.hm-2,地下部分为-28.491 9 t.hm-2,贡献率分别为72.9%和27.1%。蒙古栎林地上、地下火灾前后碳储量的分布与变化同林分类型密切相关。

摘  要:
The carbon amounts and distribution were investigated in Ledum-Querus mongolica forest and grasses-Querus mongolica forest before and after fire.Results showed that the carbon amounts of aboveground and belowground were both decreased after fire.The change of carbon amount was-33.8129 t·hm-2 in Ledum-Querus mongolica forest,-0.4994 t·hm-2 for aboveground,and-33.3135 t·hm-2 for belowground,with 1.5% and 98.5% contribution,respectively.The change of carbon amount was-104.9446t·hm-2 in grasses-Querus mongolica forest,-76.4527t·hm-2 for aboveground,and-28.4919t·hm-2 for belowground,with 72.9% and 27.1% contribution,respectively.The distribution of carbon amount of aboveground and belowground before and after fire were related with the forest type.
