| 摘 要： | 对天然次生林的群落生活型、结构、红松天然更新、群落演替进行调查。结果表明：浑河源森林公园植物种类以乔灌木为主，即天然森林与杂木林种类居多，占所有种类的近50％，有较大优势，同时反映出该地气候条件比较湿润；柞树出现的点数最多，相对频度最大；核桃楸在天然次生林中重要值为第2位。红松幼树天然更新良好；乔木树种中，假色槭、红松在更新层出现且频率较高，为进展种。核桃楸、落叶松和水曲柳在更新层没有出现，在主林层具有一定的分布，为衰退种。

| Abstract: | Forest community living-types,structure,natural regeneration of P.koraiensis and succession of nature secondary forest was surveyed.The results showed that the plant species of Hunhe River Source forest park are mainly shrub.Natural forests and broad-leaved species are in the majority,which have reached nearly 50%,meanwhile reflecting the climatic condition is humid in this district.The relative frequency of Quercus is the largest,which shows that Quercus distributes well-proportioned.The importance value of Juglans mandshurica is for the second in the nature secondary forest.Natural regeneration of younger P.koraiensis is good;A.pseudo-siebodianum and P.korsiensis are in the updated and the frequency is higher so that they are progress species.There were no J.mandshurica;Larix olgensis and Fraxinus mandshurica in the updated and distribute in the main story,so they are recession species. |
