摘要/Abstract

摘要： 运用无偏对应分析(DCA)、群落本质多样性排序和方差分析的方法,研究了东北过伐林区吉林省汪清林业局境内的四种森林类型--针阔混交林、阔叶混交林、柞木林和长白落叶松人工林的林分层次的植物物种多样性间的差异.从种类型下层植被多样性指数的比较结果来看,针阔混交林最高,阔叶混交林和落叶松人工林次之,柞木林最低.最后提出了部分经营建议.

Abstract: Four forest types, which include mixed coniferous and broad-leaved forests, mixed broad-leaved forests, Mongolian oak forests and larch plantations, were investigated in Wangqing forestry bureau, Jilin Province, an over-logged forest area in Northeastern China. Plant species diversity was studied by Detrended Correspondence Aanalysis(DCA), community intrinsic diversity ordering and variance analysis. Results showed that species diversity index of mixed coniferous and broad-leaved forests was the highest, that of mixed broad-leaved forests and Larix plantations the next, and that of Mongolian oak forests the smallest. The paper put forward silvicultural practice suggestions for maintaining and conserving diversity of these forests.

Key words: Phototactic behavior, Dark-adapted time, Helicoverpa armigera 
