对大兴安岭呼中林区主要植被类型、兴安落叶松不同林型内粗木质残体贮量进行对比研究,并利用除趋势典范对应分析对其环境梯度进行定量分析.结果表明:云杉林粗木质残体贮量较高,为0.20m3·hm-2,且不同植被类型之间呈显著性差异;兴安落叶松不同林型粗木质残体贮量在0～0.28m3·hm-2,其中偃松群落最高,为0.28m3·hm-2,泥炭藓-杜香-落叶松林最低(0),且各林型之间差异不显著.粗木质残体贮量分布格局较复杂,受多因素交叉影响;海拔、坡位等地形因子和林分年龄、郁闭度等林分条件是影响森林粗木质残体贮量的主要环境因子,二者综合作用表达了该地区森林粗木质残体贮量的空间生态梯度. The main vegetation types in Huzhong forest area of ​​Daxing’anling and the storage of coarse woody debris in different forest types of Larix gmelinii were compared and their environmental gradients were quantitatively analyzed by corresponding analysis in addition to trend.The results showed that the coarse woody The residual volume was high, 0.20m3 · hm-2, and there was a significant difference between different vegetation types. The storage volume of coarse woody debris of Larix gmelinii forest varied from 0 to 0.28m3 · hm-2, The highest values ​​were 0.28 m 3 · hm -2 for Pinus massoniana and Pinus densiflora-Larix gmelinii, and no significant difference was found between the different forest types.The distribution pattern of crude woody debris storage was complex and affected by multiple factors The topographical factors such as altitude, slope position, stand age, canopy density and other stand conditions are the main environmental factors affecting the storage of crude woody debris in the forest. The combined effect of these two factors expresses the stock of coarse woody debris in the region Space ecological gradient.
