通过对水曲柳(Fraxinus mandshurica)在红松(Pinus koraiensis)、樟子松(Pinus sylvestris Var.mongolica)、落叶松(Larix gmelini)人工林下的天然更新状况的调查分析,对其种群在人工针叶群落下发生发展特点做了比较详细的讨论。(1)在土壤水分条件比较适中的人工针叶群落中,只要在70m范围内有水曲柳种源存在,就能发生水曲柳天然更新种群。(2)现实人工针叶群落中天然发生的水曲柳种群年龄结构、空间结构(包括垂直分层和水平分布)及高生长状况都比较合理,能正常生长发育,进入主林层,与上层林木共同构成人工天然针阔混交林。此外,还对人工针叶群落中水曲柳天然更新种群生态位做了分析和讨论。
Through the investigation and analysis of natural regeneration status of Fraxinus mandshurica in Pinus koraiensis, Pinus sylvestris var. Mongolica and Larix gmelini plantations, Needle leaf community occurred under the development of a more detailed discussion. (1) In the artificial coniferous communities with moderate soil water conditions, as long as there is a provenance of Ash in 70m range, the natural regeneration population of Ash can occur. (2) The age structure, spatial structure (including vertical stratification and horizontal distribution) and high growth status of the naturally occurring species of Artemisia artificial conifers community are more reasonable, can grow normally, enter the main forest layer, and the upper layer Trees together constitute artificial natural coniferous and broad-leaved forest. In addition, we also analyzed and discussed the natural regeneration niche of Manchurian ash tree in artificial coniferous communities.
