摘  要：
采用样带网格调查法和分层株数法,研究了不同抚育强度下人天混红松林群落的演替趋势。结果表明:未透光群落中红松和五角槭属于进展种群,花曲柳属于潜在稳定种群,而蒙古栎属于衰退种群;半透光群落中红松、水曲柳和假色槭属于潜在进展种群,花曲柳和五角槭属于稳定种群,而蒙古栎属于衰退种群;全透光群落中红松、花曲柳、五角槭和灯台树属于潜在进展种群,裂叶榆、青楷槭和花楷槭属于潜在稳定种群,而蒙古栎属于衰退种群。不同林分均呈现出进展演替趋势,都向着红松硬阔叶混交林方向发展。

摘  要：
Using both the line transect method and the layered counting method,the effect of crown thinning on the succession trends of Pinus koraiensis plantations with broadleaved auxiliary species were studied.The results show that in the un-thinned control community,Pinus koraiensis and Acer mono belong to progressive populations.Fraxinus rhynchophylla belongs to a steady population,while Quercusm mongolica belongs to a declining population.In the moderate thinning community,Pinus koraiensis,Fraxinus mandshurica and Acer pseudo-sieboldianum belong to progressive populations.Fraxinus rhynchophylla and Acer mono are steady populations,while Quercusm mongolica is a declining population.In the heavy thinning community,Pinus koraiensis,Fraxinus rhynchophylla,Acer mono and Conus controversa belong to potential progressive populations.Ulmus laciniata,Acer tegmentosum and Acer ukurunduense belong to potential steady populations,while Quercusm mongolica belongs to a declining population.All succession trends in different forest stands indicated the direction of mixed pine with broad leaved auxiliary species.
