摘　　要：以浑河上游植被为研究对象,运用二元指示种分析法(TWINSPAN)对研究地区植被进行群落分类,对各群落类型特征进行分析。在提出河岸带植被生态功能适应性指标的基础上,对河岸带植被进行了生态功能适应性分组。研究发现,浑河上游河岸带植被可划分为香蒲草丛、球子蕨草丛、灯心草草丛、柳属灌丛、珍珠梅灌丛、核桃楸阔叶混交林、家榆阔叶混交林、长白落叶松林和油松林等9个群落类型,群落类型表现出突出的多样性特征,且物种组成复杂;研究地区9个群落类型可以划分为强入侵性功能组、弱入侵性功能组和高逃避性功能组3个生态适应性功能组,不同生态适应性功能组的群落中的主要物种具有明显的不同的生态对策。The vegetation in the upper reach of Hunhe was studied and the community types and its characteristics were analyzed by TWINSPAN method. Riparian plants were divided into different functional groups based on the eco-functional adaptation indices of the riparian vegetation. The riparian vegetations in the upper reach of Hunhe watershed were classified into 9 community types： Typha angustata herb community, Onoclea sensibilis vax. interrupta herb community, Juncus effusus herb community, Salix spp. shrub community, Sorbaria sorbifolia shrub community, Ulmuspumila＋broadleaved mixed community, Juglans mandshurica ＋broad-leaved mixed community, Larix olgensis forest community and Pinus tabulaeformis forest community. The community types were diverse and species compositions were complicated. 9 community types could be grouped into 3 eco-adaptation functional groups： strong invasion group, the weak invasion group and the strong avoiding group. The dominant species in each eco-adaptation functional group possessed different eco-strategy.
