摘要:

本文研究了西双版纳热带森林地区不同生境蜜蜂的物种多样性。共鉴定蜜蜂总科5科、22属、77种。8个生境的物种丰富度指数DMA的取值范围在1.914~7.877之间,多样性指数H′的范围是0.608~1.398,均匀度指数Jsw为0.716~0.956,其中保护区、雨林和灌丛拥有较高的物种丰富度指数和多样性指数,橡胶林的最小,而均匀度指数以曼养广龙山最大,农田最小。根据不同生境物种的相似性系数C进行系统聚类,8个生境在相似性系数0.169的水平时全部聚合在一起。傣族龙山在保持雨林的蜜蜂物种多样性中可以起一定的作用,但很有限,且当龙山面积越小,受人为干扰越严重时,物种多样性的损失就越大。雨林一旦被开垦为橡胶林或农田,雨林中原有的许多蜜蜂将会消失,物种多样性显著减少。

AbstractThe 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 DMA range from 11914 to 71877 , species diversity indexes H′range from 01608 to 11398 , and evenness indexes Jsw 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.
