摘要: 对色木槭天然次生林群落进行研究,测定了该群落主要乔木树种的重要值,分析了该群落的种类组成,物种多样性。结果表明:色木槭天然次生林乔木层共有16个种群,其中色木槭、蒙古栎、糠椴、山榆占明显优势,为该层的优势种和建群种;径级以<15 cm的株数最多,占总株数的87.82%,林分幼树更新数量充足。群落的Simpson指数为0.833、Shannon-wiener多样性指数为2.101、丰富度指数为2.291、均匀性指数为0.758和生态优势度指数为0.113。乔木层立木以低龄种群在群落中占优势,为了促进群落将向地带性典型植被类型演替,提出了抚育管理的建议。

Abstract: Based on investigating the population structure of natural secondary Acer mono forest in Heilongjiang province, the importance values of main tree species were measured and the floristic composition and species diversity were analyzed. The results showed that there were 16 populations in the arbor layer, A.mono, Querus mongolica, Tilia mandschurica and Ulmus macrocarpa had the obvious advantage in population, being the dominant and constructive species of the arbor layer. The diameter structure was mainly distributed in <15 cm diameter class, with 87.82% of the total numbers. The natural regeneration numbers of the saplings were adequate. The Simpson indices, diversity indices, richness indices, evenness indices, and ecological dominance of the community were 0.883, 2.101, 2.291, 0.758 and 0.113, respectively. The younger populations were dominant in the secondary forest community. The proposition of tending management was put forward for promoting evolution toward the climactic vegetation.

Key words: Acer mono, natural secondary forest, population structure, important value
