摘要
调查表明糯扎渡自然保护区有7个植被型,11个植被亚型,23个群系.保护区植被类型丰富多样,具有从热带北缘向亚热带过渡的显著特征,优势植被为季风常绿阔叶林,植被水平分布特征不突出,但垂直分布特征明显、并具有明显的植被倒置现象.文中以充分的资料补充了云南植被的新类型,指出保护区特殊的澜沧栎林、榆绿木林为落叶季雨林,前者是云南植被的新记录类型;江边刺葵群落则是云南热区河谷植被的新记录类型.
It was showed by investigation and analysis that there were 7 vegetation types, 11 vegetation subtypes, 23 formations in Nuozhadu Nature Reserve, Yunnan, China. The vegetation types in the reserve were abundant, dominated by monsoon evergreen broad-leaved forest, demonstrating typical transitional characteristics from north-tropic to subtropics. The horizontal distribution feature of the vegetations was not so clear but the vertical distribution feature was obvious, showing upside-down distribution phenomenon. Vegetation types in Yunnan were supplemented by this study with sufficient new materials. The Quercus kingiana forest in Nuozhadu Nature Reserve was a newly recorded deciduous seasonal rainforest, Anogeissus acuminata var. lanceolata forest belonged to deciduous seasonal rainforest, and Phoenix roebelenii community was a newly recorded vegetation type in dry-hot valley area of Yunnan Province.
