摘要
从物种组成、多样性及重要值3个方面对山坡次生蒙古栎林和山间谷地杂木林2种生境下野生平贝母的伴生物种进行了调查分析。结果表明:蒙古栎林计有伴生植物50科88属100种;杂木林有伴生植物47科96属104种。蒙古栎林中乔木、灌木和草本层的物种多样性指数(H)和均匀度指数(E)依次增加,而杂木林中灌木层多样性指数和均匀度指数均低于乔木和草本层。2种生境中伴生植物的丰富度指数(R)排序均为草本>乔木>灌木。在蒙古栎林中蒙古栎的重要值最大,为25.418,显著大于其它物种,是群落中的优势种。在杂木林中主要植物的重要值则差异明显。
Based on survey and analysis on species composition,diversity and important value,the traits of Quercusmongolica forest and shaw of Fritillaria ussuriensis Maxim.were studied.The results showed that,100 higher plant species belong to50 families 88genera were found in Quercus mongolicaforest,and that of shaw was 104 speices belong to 47 families 96genera.Tree,shrub and herb diversity indices and evenness increase by degress in Quercus mongolicaforest.However,shrub diversity indices and evenness was lower than that of tree and herb in shaw.Richness index in both habitats were herbshrubtree.Quercus mongolica（IV=25.418）was considerably important than other accompanying species in Quercus mongolicaforest.However,important value of species in shaw had no significant difference.
