长白山针叶混交林群落特征分析——以和龙市为例

Analysis on Community Characteristics of Coniferous Mixed Forest in Changbai Mountain——Taking Helong City for Example

为有效掌握长白山的针叶混交林森林群落,在和龙市采取大样地调查方法选取典型样地,进行乔木、灌木、草本的现地调查。结果表明:乔木林中,以红松、臭冷杉等针叶树种为优势种,株数和蓄积量所占百分比分别为58.62%和68.67%,伴随紫椴、槭树类阔叶树种,株数和蓄积量所占百分比分别为29.15%和18.93%;灌木以长白忍冬、暴马丁香、柳叶绣线菊为优势种,株数占38.75%;草本以山芹、白毛羊胡子草为优势种,株数占66.32%,表明该森林群落物种多样性丰富,群落结构稳定。

In order to effectively grasp the coniferous mixed forest community in Changbai Mountain, the large-scale plot survey method was adopted to select typical plots in Helong City for on-site investigation of trees, shrubs and herbs. The results showed that conifer species, such as Pinus koraiensis and Abies nephrolepis, were the dominant species in the arboreal forest, and the percentages of the plant number and the volume were 58.62 % and 68.67 %, respectively. The percentages of the plant number and the volume of broad-leaved species, such as Tilia amurensis and Acer, were 29.15 % and 18.93 %, respectively. The dominant shrub species were Lonicera ruprechtiana, Syringa reticulate var. amurensis and Spiraea salicifolia, and the percentage of the plant number was 38.75 %. The dominant herb species were Ostericum sieboldii and Eriophorum vaginatum, and the percentage of the plant number was 66.32 %. The species diversity of the forest community was rich and the community structure was stable.
