摘  要：
澜沧江省级自然保护区位于澜沧江中游临沧市境内。该区域植被类型随海拔升高而呈垂直分布规律。在以往的研究中忽视了澜沧江两岸低海拔区域植被的研究。文章以临沧市临翔区邦东乡沿江两岸低海拔植物群落为主要对象,分析该区域植被类型及其物种组成,以期为该区域生物多样性管理提供依据。研究发现,在沿江两岸海拔750～1 400 m区域,共计发现7个植被型、8个植被亚型、8个群系及8个群落类型。除季风常绿阔叶林外,其他7个植被亚型均为本次调查新发现,其中热带季雨林与暖热性针叶林是研究区域主要的植被类型,而暖热性针叶林与季风常绿阔叶林则受破坏较大,分别产生暖热性稀树灌木草丛和干热性稀树灌木草丛,而干热灌丛则小面积分布。并根据澜沧江周期性枯水期出现的狗牙根群落,新提出河流消落带植被类型。

摘  要：
Lancangjiang Provincial Nature Reserve is located in Lincang City, the middle area of Lancang River. The vegetation types in this area are vertical distribution with the increase of altitude. The previous study often has neglected vegetation types of lower altitude both sides of Lancang River. This paper analyzed the vegetation types and species composition of the low-altitude plant communities along the river in Bangdong Town, Linxiang District, Lincang City, in order to provide the basis for biodiversity management in the region. A total of 7 vegetation types, 8 vegetation subtypes, 8 formations and 8 community types were found in the area with altitude ranged from 750 to 1 400 m. Except for the monsoon evergreen broad-leaved forest,the other 7 vegetation subtypes were firstly found in this survey. The tropical monsoon forest and warm coniferous forest were the main vegetation types in the study area,while warm coniferous forest and monsoon evergreen broad-leaved forest were greatly damaged,respectively producing warm sparse shrub and grass and dry hot sparse shrub and grass which was distributed in a small area.Based on the Cynodon dactylon community in the Lancang River during the periodic dry season,this vegetation was proposed in the hydro-fluctuation belt.
