摘要
研究了长白山阔叶红松林内早春植物群落特征 ,为进一步深入研究其在森林生态系统中物质循环和能量流动等生态功能奠定基础。早春植物主要有12种2变种 ,隶属于8属4科。按Raunkiaer生活型分类标准统计 ,早春植物都属于地下芽植物。分别以相对多度、相对频度、相对显著度和重要值为标准对各种早春植物进行排序 ,重要值排在前5位的植物分别是黑水银莲花、朝鲜银莲花、荷青花、五福花、大人字果。早春植物群落物种多样性的Shannon指数为2.5229,群落均匀度为0.9560,生态优势度为0.3212。
The community characteristics of the early-spring herbs in broadleaved-Korean pine forest of Changbai Mountain was studˉied,which was an essential prerequisite in studying material and energy flows in forest ecosystem.There are mainly12species and2mutation plants of early-spring herbs,belonging to8genera and4families.According to Raunkiaer life type classification standard,early-spring herbs all belong to geophytes.The quantity characteristics in sequence of the relative abundance,relative frequency,relˉative distinction and importance were studied.The first5relatively important species are:Anemon amurensis,A.rosii,Hylomecon vernalis,Adoxa moschatellina,and Enemion raddeanum.The diversity based on Shannon index of early-spring herbs is2.5229,the equality is0.9560,and the dominance is0.3212.
