Abstract: 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.

Key words: Heterogeneous landscape, Bryophyte, Community diversity, non biological factor, non-mycorrhizal plant, symbiosis, biological factor
