Urban forests play an important role in improving and beautifying the eco-environment of a city. In this paper, based on the current situation of landscape classification, the indices of diversity, dominance, fragmentation and patch density were studied. With principle of ecology, the diversity of forest landscape of Maofeng Mountain forest park was analyzed in three respects, forest landscape type diversity, patch diversity and pattern diversity. Results showed thatrthe orchard and bamboo forest were highly fragmented; broadleaved mixed forest remained completed, fragmentation was smallest, whi'e Castanopsis fissa forest was biggest; the distributions proportion of every landscape types were uneven, the proportion differences between landscape types which constituted Maofeng Mountain forest park were smaller than that of Guangzhou area.
