摘要: 昆明呼马山公园人工桉树林乔木层树种为单一的直杆桉,林下植被类型有灌木-草本型。草本层紫茎泽兰这一外来物种在整个林地的草本层中占据绝对优势,阳坡林下植被的Shannon-Wiener指数H/和Simpson指数D都比阴坡的要高。灌木层生物量低于草本层的生物量。

Abstract: In Humashan Park of Kunming, tree species of artificial eucalyptus forest was only straight rod Eucalyptus.Under-story vegetation types are shrubs and herbaceous-type,not pure herbal type. This was the initial stage of development of plantation as one of the main features. Eupatorium adenophorum, the alien species in the herb layer took absolute superiority. Since it had strong survival capacity for rapid development,it affected the management of artificial eucalyptus. The biomass of shrub layers was lower than that of herbaceous layer. Shannon-Wiener index H and Simpson index D of under-story vegetation of sunny slope were higher than the ones of shady slope.

Key words: Eucalyptus, under-story vegetation, plant diversity, biomass
