摘  要:
通过调查研究,在红松阔叶林、近熟林和中龄林内调查到的早春植物分别为34,43,50种。这3种林型在早春阶段都以早春植物占主导地位,次生林内先锋草本植物的比重增加。中龄林、近熟林和红松阔叶林的物种丰富度分别为8.098 8,7.426 9,7.383 0;Simpson指数分别为0.616 4,0.753 2,0.863 8,Shannon-Wiener指数分别为2.342 1,2.272 1,2.380 0;生态优势度指数分别为0.383 6,0.246 7,0.174 9。以上分析结果表明:在早春阶段,随着次生演替的发展,群落的物种丰富度下降,生物多样性上升,群落的稳定性增加,逐步接近原始林的水平。

摘  要:
Early-spring herbs are central synusia to the plant community in Korean pine broad-leaved forest.By investigation,the number of species in Korean pine broad-leaved forest,Closely mature forest and Middle-year forest is 34,43 and 50 respectively.These three forest types are dominant by ephemeral plants in early spring,yet the proportion of pioneer herbs in secondary forest increases.The species richness of Middle-year forest,Closely mature forest and Korean pine broad-leaved forest is 8.098 8,7.426 9,and 7.383 0 respectively;the Simpson index is 0.616 4,0.753 2 and 0.863 8;the Shannon-wiener index is 2.342 1,2.272 1 and 2.380 0;the ecological dominance is 0.383 6,0.246 7 and 0.174 9.These results show that as secondary succession develops,the species richness decreases,the biodiversity indices such as Shannon-wiener and Simpson index increase,the stability rises,gradually approaching the level of primitive forest.
