摘要
在一个生长季节内,每月中旬对原始红松阔叶林草本植物调查5次,共调查到草本植物125种。调查结果显示,草本植物季节变化较明显,5~9月草本植物的种数分别为34,65,61,59,40;占优势的物种因月份而异;Simpson多样性指数各个月份依次为0.8638,0.9459,0.9349,0.9039,0.8865;Shannon-wiener指数依次为2.3799,3.2931,3.1643,2.8490,2.6086;均匀度指数依次为0.6749,0.7888,0.7697,0.6987,0.7071;一年内草本植物垂直结构有明显的分层现象。
The diversity of woodland herbs is one of the most striking features of Korean pine broad-leaved forest.According to 5 times of investigation in a whole growth season,the diversity has a great change in different months.There are about 125 species of herbs in this type of forest.From May to Sep,the number of species is 34,65,61,59 and 40 respectively;the Simpson index is 0.863 8,0.945 9,0.934 9,0.903 9 and 0.886 5;the Shannon-wiener is 2.379 9,3.293 1,3.164 3,2.849 0 and 2.608 6;the Evenness index is 0.674 ...
