摘要
苔藓植物是一类敏感的环境指示植物．通过对上海市市区及市郊５种景观类型中苔藓植物群落的取样调查，从丰富性、均匀性、相似性等方面进行了多种α和β多样性指数分析．结果表明，５种生境中的苔藓群落多样性指数呈现出明显的梯度变化，对景观异质性有较好指示作用；
Bryophyte is a kind of sensitive plant that indicates the quality of environment. Based on the
sampling of the bryophyte communities of five heterogeneous landscapes in Shanghai city and
its suburbs, the analysis on α and β diversity related with richness, evenness and similarity
shows that the diversity index of bryophyte communities in five habitats obviously appeared
gradient change, which well indicated the landscape heterogeneity. the mean height of
bryophytes and the ratio of large ones varied regularly with different landscapes.
