| 摘 要： | 通过对2种混交林林下物种多样性丰富度进行比较研究,结果表明:(1)落桦混交林(华北落叶松+白桦)灌木丛中榛子是最优势的灌木,而油松+蒙古栎混交林灌木丛以三裂叶绣线菊为最优势的灌木;落桦混交林灌木层主要植被种类与油松+蒙古栎混交林相比较少。(2)落桦混交林草本层草乌头、牛蒡为优势种,油松+蒙古栎混交林具有优势的草本为细叶苔草与林地早熟禾;落桦混交林草本层组成种类较少,而油松+蒙古栎混交林草本层组成植被种类较丰富。(3)落桦混交林物种丰富度比油松+蒙古栎混交林要低,2种林分的灌木层Simpson指数、Shannon-Wiener指数均比草本层要低,说明灌木层的多样性要比草本层低;2种林分的灌木层Pielou指数均比草本层要低,说明灌木层的均匀度要比草本层低。
