长白山云冷杉针阔混交林两个演替阶段乔木的种间联结性

摘要: 基于2×2联列表和方差比率,通过χ2统计量检验和种间联结系数值计算,对杨桦次生林和云冷杉针阔混交林阶段林分总体种间联结性进行了分析。结果表明:杨桦次生林群落内出现的12个乔木树种之间的总体关联性方差比率为0.932,接近1,表现为无相关性;在针阔混交林阶段,群落主要种间的总体关联性表现为正相关,说明该阶段的群落已处于和该地区环境条件相适应的稳定阶段,群落总体正关联性随着演替进程而加强。竞争的最后结果将导致杨桦退出先锋树种阶段,并被地带性顶级树种云冷杉代替。多树种间总体联结性反映了群落内各树种间相关性的总体趋势,树木种群的关联关系进一步说明该群落处于杨桦次生林向云冷杉针阔混交林过渡的阶段。
