Abstract: The species composition and diversity of bees in eight different habitats of the tropical forest region in Xishuangbanna were studied. 77 species , belonging to five families and 20 genera , were recognized. The diversity measurements of bees in different habitats showed that values of species richness indexes D_MA range from 11914 to 71877 , species diversity indexes H′range from 01608 to 11398 , and evenness indexes J_sw range from 01716 to 019561 Based on similarity coefficients C in table 3 , eight habitats can be clustered at the level of 01169 with the systematic clustering. Holy Hills of Dai nationality play a limited role in the conservation of bee species in rain forest , which is affected by the decreasing areas of Holy Hills and human disturbance. If the tropical rain forest is exploited for cultivation , many species of bees in the rain forest will disappear and will be substituted by some species of relatively extensive distribution. Number of species will be significantly decreased.
