针对针叶林阔叶化改造目标的关键问题,通过大量的调查研究,分析树种间的关联程度、物种多样性程度、森林群落的模糊聚类和自然演替序列,表明针叶林的阔叶化改造目标,要根据演替进程和立地条件,分别确定由于时间和生境不同而产生的阶段目标和环境条件制约下的不同目标群落类型,实行科学分类指导。
mongolica populations was analyzed along four altitude grades, three community types and three latitude grades by using ISSR DNA technique.

In this paper,the community types of broadleaved-Korean pine mixed forest in Northeast China were identified,and the groups of tree relationship were established based on TWINSPAN.
运用TWINSPAN分类方法,对我国东北阔叶红松林群落类型进行划分,对乔木层树种进行聚类,并对东北地区长白山、大秃顶子山、平顶山和丰林保护区4个样点的物种多样性进行对比研究。
With the help of TWINSPAN classification and DCA ordination,the secondary forests were classified into 5 community types,including Fraxinus rhynchophylla community,Quercus mongolica community,Broadleaved stand community,F.
结合DCA排序和TW IN SPAN分类结果,将辽东山区天然次生林划分为5个群落类型:花曲柳林、蒙古栎林、阔叶混交林、水曲柳林、胡桃楸林。
