摘　　要：１９９３年１０—１１月和１９９４年３—５月在西双版纳州曼俄龙山、城子龙山、曼养广龙山及保护区对照样地进行鸟类调查时，观察到鸟类１０４种，隶属２７科，另４亚科，８目，香农多样性指数以保护区对照样地为最高，曼俄龙山和城子龙山为次，曼养广龙山为最低。均匀度也呈现相同的变化趋势。ｔ检验表明曼俄龙山和城子龙山的香农多样性指数无显著性差异。３个龙山和保护区对照样地共有的种类１１种，３个龙山的共有鸟类为１１种。片断热带雨林中鸟类的多样性受多种因素共同影响，片断热带雨林的面积、距较大原始雨林的距离。A census to bird species diversity was conducted in fragmented rainforest patches at Xishuangbanna,Yunnan Province, China from October to November,1993,and from March to May,1994 The sample localities were Mane Holy Hill (3 ha) and Chengzi Holy Hill (4 ha) at Menglun,Mengla county,and Manyangguang Holy Hill (20 ha) at Xiaojie,Jinghong County The control locality was a part of Xishuangbanna National Nature Reserve at Menglun (census area was about 100 ha) 104 species, which belonged to 27 families (4 subfamilies), 8 orders,were recorded in above localities In the reserve,89 species were observed At Manyangguang Holy Hill,30 species were found Both at Mane and Chengzi Holy Hills 38 species were recorded The Shannon index was highest at the reserve,while it was lowest at Manyangguang At Mane the Shannon index was slightly higher than at Chengzi,but a t -test showed they were not significantly different The change in trend of evenness was similar to that of Shannon index 11 species were common at all four localities The species found at all three holy hills were also those 11 species The number of species recorded at both the reserve and Chengzi were the highest (36 species), while the number of species recorded at both Manyangguang and Chengzi was the lowest (13 species) A dendrogram constructed by using the Jaccard index showed that similarity between Chengzi and the reserve was the highest (0 3956),while similarity between Mane and Manyangguang was the second highest (0 3878) This is probably because habitats around Mane and Manyangguang were similar to each other Both sites were surrounded by farm land and rubber plantation There was a large secondary forest at one side of Chengzi This showed that the more similar the surrounding habitats, the more common the species at the two localities were A dendrogram constructed by using the Sorenson quantitative index also showed that similarity of Mane to Manyangguang were the highest,Chengzi had a higher similarity to them
