崆峒山维管植物区系及多样性研究

Study on Flora and Diversity of Vascular Plants in Kongtong Mountain

以崆峒山为研究区域,通过样线法和典型样地法对崆峒山植物群落进行调查,从植物区系成分和物种多样性方面对崆峒山维管植物多样性进行了分析。结果表明:崆峒山共有102科393属811种维管植物,其中有新分布植物16种,珍稀濒危植物9种;多样性指数显示阳坡植物多样性较阴坡高;区系分析表明,崆峒山植物种类组成比较丰富,地理成分复杂,属典型的北温带性质,中国特有属有5属。本研究可为崆峒山植物资源的保护、开发和管理提供理论依据。

In this study,we used Kongtong Mountain as the research area,and investigated the plant community of the Kongtong Mountain by the method of sample line and typical plot.The diversity of vascular plants in Kongtong Mountain was analyzed from the aspects of flora composition and species diversity.The results showed that there were 811 species of vascular plants,belonging to 102 families and 393 genus,including 16 newly recorded species,and 9 rare and endangered plants in this mountain range.Diversity indexes showed that plant diversity on the sunny slope was higher than that on the shaded slope.The floristic analysis showed that there was rich in plant species and the geographical constituent was complex,it was a typical northern temperate,and there were 5 genus endemic to China.This research results could provide a theoretical basis to protect,utilization and management of plant resource in Kongtong Mountain.
