Comparative Investigation Of Birds Diversity Of 6 Nature Reserve In Sanjiangyuan National Nature Reserve Of Qinghai Province

In an investigation of the avian community structure, using line-intercept method and quadrat method in Maixiu Nature Reserve, Zhongtie-Jungong Nature Reserve, Makehe Nature Reserve, Zhalinghu-Erlinghu Nature Reserve, Jiangxi Nature Reserve and Angsai Nature Reserve of Sanjiangyuan National Nature Reserve, in May to September 2013 and April to September 2014, by the formula of Shannon-Wiener index and evenness index.A total of 153 bird species belonging to 15 orders 44 families were counted in the 6 Nature Reserve. Totally 58 species of avian belonging to 7 orders 26 families were recorded in Maixiu Nature Reserve,84 species belonging to 13 orders 28 families were recorded in Zhongtie-Jungong Nature Reserve,73 species belonging to 12 orders 30 families were recorded in Makehe Nature Reserve,28 species belonging to 9 orders 18 families were recorded in Zhalinghu-Erlinghu Nature Reserve,64 species belonging to 12 orders 28 families were recorded in Jiangxi Nature Reserve,39 species belonging to 7 orders 17 families were recorded in Angsai Nature Reserve. The bird diversity index were: 3.6417,3.1670,3.7183,2.2948,3-5920,3.1261,the evenness index were: 0.8969,0.7110,0.8667,0.6887,0.8605,0.8474,the dominance index were: 0.0361,0.0948,0.0349,0.1424,0.0449,0.0583.The results showed:(1) Passeriforme, Breeding birds (summer resident and migratory birds) were the main birds in the 6 Nature Reserve, Palaearctic birds and dispersed birds, which were much more than Oriental birds.(2) Songbirds were the main birds in the 6 Nature Reserve.(3) The bird diversity index from high to low were:Makehe Nature Reserve>Maixiu Nature Reserve>Jiangxi Nature Reserve>Zhongtie-Jungong Nature Reserve>Angsai Nature Reserve>Zhalinghu-Erlinghu Nature Reserve; the evenness index from high to low were:Maixiu Nature Reserve>Makehe Nature Reserve> Jiangxi Nature Reserve>Angsai Nature Reserve>Zhongtie-Jungong Nature Reserve> Zhalinghu-Erlinghu Nature Reserve; the dominance index from high to low were: Zhalinghu-Erlinghu Nature Reserve>Zhongtie-Jungong Nature Reserve>Angsai Nature Reserve Jiangxi Nature Reserve>Maixiu Nature Reserve>Makehe Nature Reserve.(4) Makehe Nature Reserve and Jiangxi Nature Reserve have the highest similarity coefficient, secondly is the Makehe Nature Reserve and Maixiu Nature Reserve, Zhalinghu-Erlinghu Nature Reserve and Maixiu Nature Reserve have the lowest similarity coefficient.(5) 3 new bird records of Qinghai Province were found and 9 of Sanjiangyuan National Nature Reserve were found.(6) Based on the results of investigation, we analyzed the bird diversity, fauna and the interference factors of the birds. Relevant protection suggestions had been proposed.
