摘　　要：糯扎渡省级自然保护区地处澜沧江下游,糯扎渡水电站两侧,拥有丰富的生物资源。2018年9月—2019年10月期间,采用样线法对保护区鸟类多样性进行调查,共记录到鸟类18目67科148属222种。鸟类的区系构成以东洋区成分为主,共174种,占繁殖鸟类种数的78.38%,古北种6种(占2.7%),广布种42种(占18.92%)。多样性指数分析表明,澜沧片核心区、思茅片核心区的鸟类多样性最丰富。澜沧片区的鸟类Pielou均匀度指数、Simpson指数相对较高,思茅片区相对较低。思茅片区样线选取经过部分鸟类集居点,是造成Pielou均匀度指数、Simpson指数偏低的主要因素。Nuozhadu Provincial Nature Reserve is located in the down-stream area of Lancang River,on the both sides of Nuozhadu Hydropower Station,which is rich in biodiversity resources.From September 2018 to October 2019,by using the line transect method to investigate the avian diversity,a total of 222 species were recorded,which belonged to 148 genera,67 families and 18 orders.The fauna of birds was mainly composed of 174 Oriental species,accounting for 78.38%of the total number of breeding birds,6 Palaerctic species(2.7%)and 42 widely distributed species(18.92%).The diversity index analysis showed that the bird diversity in Simao core area and Lancang core area was the most abundant.The Pielou evenness index and the Simpson index of Lancang area were higher than those of Simao area.The main reason for the low Pielou evenness index and Simpson index of Simao area was that the sampling line crossed some birds’settlements.
