摘要:

采用法瑞地植物学派的样地调查法记录了澜沧江中上游河谷中一独特的硬叶小叶常绿阔叶林类型——锈鳞木樨榄、清香木群丛。该群丛由南向北分布于1300~1900m的河谷下部,对群落外貌、生活型与生长型、植物种类科属的组成、分布区类型等进行了分析。结果表明:(1) 群落结构简单,物种数平均为18种;(2) 生活型以高位芽植物居多,生长型以草本居多;(3) 群落中计有维管植物116种,隶属于39科,84属;(4) 植物科级、属级水平上均显示出了热带性质,植物区系表现出一定的古老性,反映了与古地中海硬叶小叶林的历史渊源。该植物群丛适应澜沧江干热-干暖河谷气候,分布区域狭窄,是一类值得重点保护和深入研究的植被类型。

Abstract:

 An unique scleromicrophyllous evergreen broadleaved community in the valley of Lancang (upper Mekong) River was recorded using the methodology of BraunBlanquet’s relevé. The plant community was nominated by Association Olea ferruginea, Pistacia weinmannifolia. It was mainly happened at altitude 1300m to 1900m above sea level along the river banks. Its physiognomy, life/growth form, and floristic components were summarized, depending fieldcollected releves. The results indicated community structure was relatively simple, with average species number of 18; Phanerophytes were the most common life form, and growth form was dominated by herbs; There were 116 vascular species, 39 families, and 84 genera in 15 relevés; Its flora had a tropical characteristics at family and genus level. This association was supposed to be a relic vegetation of paleomediterrean subtropical vegetation which is characterized by small and scelrophyllous leaves. With growing human impact of dams construction, this plant community type which remains and evolves in a narrow valley were worth of protection and further research.
