摘要/Abstract

摘要： 大兴安岭林区是我国重要的森林资源分布区，森林生物量和碳储量巨大，对于维持东北地区生态系统碳平衡具有重要意义。本文基于野外样地调查数据，分析了大兴安岭地区林分尺度上森林生态系统的生物量及其分配特征、生物量各组分间的数量关系，并利用CANOCO 4.5对调查样地进行排序轴分类，划分了7种典型的植物群落，探讨了群落生态系统生物量分配特征差异及其与环境因子的关系。结果表明：大兴安岭地区森林生态系统生物量密度范围为17.83～283.93 t·hm^-2，生物量密度均值由大到小为蒙古栎林＞兴安落叶松林＞樟子松林。相比蒙古栎林，针叶林地下生物量和凋落物层生物量比重较大，且在海拔梯度上，植物群落的地理分布和生物量分配特征差异明显。

Abstract: The Great Xing’an Mountains is one of the most important regions with abundant forest resources. Its large amounts of forest biomass and carbon stocks have significant implications for maintaining the carbon balance of Northeast China. Based on field investigation data, the forest biomass and its allocation characteristics as well as the quantitative relationships among biomass of each component of forest ecosystems at the stand level in the Great Xing’an Mountains were analyzed. Furthermore, the plots surveyed were divided into seven community types by ordination axes clustering analysis with the software of CANOCO 4.5 on species composition, and the biomass allocation characteristics of each of the community types and the relationship with environmental factors were elucidated. The results showed that the total forest biomass in the Great Xing’an Mountains ranged from 17.83 to 283.93 t·hm^-2, and the average biomass density of each vegetation type was in the order of Quercus mongolica forest > larch forest > Pinus sylvestris var. mongolica forest. Compared with Q. mongolica forest, the percentage of underground biomass or litter biomass in coniferous forests was larger. Meantime, the differences of geographical distribution of plant community as well as biomass allocation characteristics were obvious along the elevation gradient.
