以黑龙江省晨明林场为例,从群落组成与物种多样性、遮荫植物、生活型、伴生植物的重要值等4个方面对平贝母伴生蒙古栎林群落进行了调查分析。结果表明:(1)该群落乔、灌、草发育比较完善,物种多样性较高,共有高等植物50科88属100种;(2)主要遮荫植物为蒙古栎、胡枝子、榛等11种乔灌木;(3)生活型谱以地面芽(37%)和隐芽植物(31%)比例最高,与本地区冬季漫长寒冷、干燥的温带大陆性气候特征相一致;(4)蒙古栎(IV=25.418)、胡枝子(IV=11.155)、黑桦(IV=9.140)等14种植物是群落中最重要的伴生种。
Taking Chenming Forest Farm in Heilongjiang Province as an example, the communities of Quercus mongolica and Quercus mongolica were surveyed from four aspects, such as community composition, species diversity, shady plants, life forms and important values of accompanying plants. The results showed that: (1) The community of Qiao, Shrub and grass developed well and the species diversity was high. There were 100 families of 88 genera and 50 species of higher plants in the community. (2) The main shady plants were Quercus mongolica, Lespedeza, Hazel and so on. (3) In the life spectrum, the highest proportion of ground buds (37%) and cryptophytes (31%) is consistent with the long cold and dry temperate continental climate in the winter of this region; (4) (IV = 25.418), Lespedeza davidiana (IV = 11.155) and Black birch (IV = 9.140) were the most important companion species in the community.
