西双版纳部分地区鸟类多样性初步考察

１９９２年１２月，１９９３年１１月及１９９４年４～５月，对西双版纳自然保护区内外的数个工作点进行了鸟类物种多样性的调查，共记录鸟类１９０种。分析表明雀形目鸟类物种多样性状态尚佳，而非雀形目鸟类类群（科种）多样性及物种多样性状态均恶化趋势，保护区内鸟类物种多样性状态明显较好，傣族墓葬地之龙山因依傍村落，农田及其他多种生境而具有相当丰富的鸟类物种多样性，是保护鸟类物种多样性不可忽视的一个方面，研究表明

THE FIRST REPORT ON BIRD DIVERSITY IN XISHUANGBANNA

An avian survey was conducted inside and outside the reserves in Xishuangbanna in December,1992,November,1993 and April through May,1993,During the survey,190 species were recorded. The species diversity was good in Passeriformes but severe in Non-passeriformes. The diversity inside the reserve was higher than that outside ones. Longshans,the burial grounds of Dai nationality,had pretty good bird diversity,and seemed to play a special role in bird conservation. In limited time and space,habitat diversity was the main force controlling bird species diversity. Using species richness or diversity index as the only parameter might reach a wrong conclusion on evaluating conservation situation in an environment because of a majority of the common species recorded. Thus,it is suggested that the number of special bird species only recorded in one site should also be considered as a parameter in comparing bird diversity situation in different environments.
