【摘要】 运用扩散系数(C)、丛生指数(I)、扩散指数(Iδ)、聚块性指数(M*/)、Cassie R.M.指数(CA)等聚集度指标,对南岳衡山甜槠林群落的类型、结构特征、数量特征进行了分析。结果表明:该处甜槠林群落具有群落面积小、分布较孤立、物种组成较少、层次结构明显、群落中甜槠多呈随机状分布的特点。该结果为保护南岳衡山这类原生性的植物群落提供了科学依据。更多还原

【Abstract】 A detailed analysis on the community types,structure characteristics,amount features,quantitative spatial distribution patterns of Castanopsis eyrei forest in Nanyue Hengshan Mountain was mode through the following index such as diffusion coefficient(C),proliferation index(I),diffusion index(Iδ),clump index(M*/),Cassie R.M.index(CA).The results show that the Castanopsis eyrei forest had the following characteristics: the communities was smaller than others in area,distributed with isolation,had less species and simple structure;and the Castanopsis eyrei population in the communities showed a random distribution.It also provides a scientific basis for protecting such original forest communities.更多还原
