Abstract:: The wild grass, bush community, artificial mixed forest were regarded and natural secondary forest were regarded as the research subject of different stages in the process of ecological construction aimed at soil and water conservation around Napahai Lake in the northwest of Yunnan Province.The change of those community structures was studied by using spatio-temporal substitution method.The community spatial structure, the species diversity, evenness, ecological dominance in four ecosystems were analyzed, the results show that community structures become more and more complicated from the wild grass to natural secondary forest.Biomass of shrub layers of the wild grass, five-year-old bush community, thirteen-year-old artificial mixed forest and fifteenyear-old natural secondary forest was 0, 8.1704t/hm², 2.0449 t/hm², 3.7965 t/hm², and that of their herb was 7.4912 t/hm², 4.6812 t/hm², 3.9852 t/hm² and 1.6966 t/hm² respectively.
