Abstract:

There are 73 families, 139 genera and 179 species distributed in 0.1 ha of different land Use Stages of Daka and 70 families 146 genera 166 species distributed in 0.08 ha different different land use stages of Baka, Xishuangbanna. The cosmopolitan families, such as Gramineae, Compositae and Papiloinaceae take about 20% in Daka and 30% in Baka that agricultural activities caused decrease of tropical families and subtropical families comparing with tropical rainforest. Species α - diversity and β - diver-sity of different land Use Stages of Daka and Baka was measured and studied using the methods of Gleason' species richness index, Shannon-Wiennner index, Pielous' evenness index, Whittaker index and Jaccard' coefficient index. The results of the diversity indices varied greatly that means different land Use Stages had different species composition and led to different vegetation succession.

Key words: Land management pattern, Plant diversity, Agrobiodiversity assessment (ABA), Xishuangbanna
