<正>为了加强对苔藓生态学的认识 ,应用缀块思路及相关的生态学理论 ,分析了龙王山常绿阔叶林 5种不同生境缀块中石生藓类的分布格局。结果发现石生藓类H′、D、βR、βc、βT、βCJ等α、β多样性指数与各缀块的受干扰程度密切相关 ,表现出明显的梯度变化 ,真实反映了各缀块生境异质性。α、β多样性分析可以应用于缀块水平的物种组成及演替分析

In order to prove the understanding of moss ecology,distribution patterns of Petrophytia were investigated,based on patchy and ecological theory,for five different habitats of evergreen broadleaved forest at Longwangshan.The results showed that α & β diversity indexes(e.g. H’?D?β R?β c?β T?C J?β CJ )were closely related with degree of disturbance and obviously appeared gradient change,which well indicated the habitat heterogeneity.Diversity analyses of α & β could be used in investigation of species structure and evolution at patchy level.
