摘要
以浙江新昌穿岩十九峰和千丈幽谷两处典型丹霞地貌为例,采用典型样方法对其岩生植被群落进行调查研究.结果表明,该区域内植物种类较少,共有维管束植物30科39属48种,地理成分复杂,主要由北温带和泛热带成分组成,并具有明显的过渡性特征;群落类型主要有山类芦(Neyraudia montana)草甸、晚红瓦松(Orostachys erubescens)+藓状景天(Sedum polytrichoides)、薜荔(Ficus pumila)灌丛等.丰富度指数、多样性指数从大到小依次为:草本层、灌木层、苔藓层;均匀度指数从大到小依次为灌木层、苔藓层、草本层.
Take Changyanshijiufeng and Qianzhangyougu in Xinchang, Zhejiang as examples ,this paper made a survey on the rock vegetation in Danxia landform. The results showed that 30 families, 39 genus and 48 species vascular plants were found there. The main community types were Form. Neyraudia montana, Form. Orostachys erubescens＋Sedum polytrichoides , form. Ficus pumila and so on. The composition of flora was complex, and the north temperate and pantropic floristic elements occupied a certain proportion with especially obvious transitional character. The order of species richness and diversity index were： herb layershrub layermoss layer, and the evenness index was： shrub layer moss layerherb layer.
