摘要
运用群落学的调查方法,对广西木论国家级自然保护区麻栗坡兜兰的种群生存环境、种群结构和空间分布等群落学特征进行了初步调查分析。结果表明:麻栗坡兜兰产地的气候、植被、土壤和其它环境因子与麻栗坡兜兰的生存有着密切的关系,以聚集群居生长,分布于石灰岩森林的岩石宽缝中的积聚较多富含腐殖质的腐叶土层上。凡生长在保存度完好的森林环境且腐质层土厚度大于8cm的条件下,其植株长势旺盛,叶片肥厚、宽大。研究区内植物群落的科、属组成以单种属为主,属的成分与热带、亚热带的关系密切。麻栗坡兜兰生存与环境的关系以及导致濒危的原因还需更进一步研究。
The characteristics, including habitat, population construction and spatial distribution of Paphiopedilum rnalipoense community in Mulun Nature Reserve were preliminarily researched via standard quadrat sampling. The results indicated that climate, vegetation, soil and other environmental factors were significantly related to the occurrence of Paphiopedilurn rnalipoense. Paphiopedilurn malipoense were endemic to limestone forest, growing gregariously in wide rock gap with rotten leaves and abundant humus. Paphiopedilum malipoense growing in well protected forest and humus over 8 cm depth had thick and wide leaves. The family and genus of the community were dominated by monospecific,and genus composition was closely related to tropical and subtropical composition. The relationship between Paphiopedilurn rnalipoense survival and environment, and the factors leading Paphiopedilurn malipoense to endangered status need further research.
