| 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的人天混红松林群落演替趋势。结果表明:未透光群落中红松和五角槭属于进展种群,花楷槭属于稳定种群,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、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,都向红松硬阔叶混交林方向发展。

| Abstract: | An experiment was conducted to study the effect of crown thinning(unthinned control,moderate thinning,heavy thinning) on the succession trend of Korean pine plantations with broadleaved auxiliary species in the forest region of eastern Liaoning Province using the line transect method and the layered counting method.Results show that,in the unthinned control community,Pinus koraiensis and Acer mono belong to progressive populations,Acer ukurunduense belongs to a steady population,while Quercus mongolica belo... |
