Diversity Investigation And Research of Birds in Sichuan Huaying Mountain Nature Reserve

采用样线和样点法相结合,于2014年4月15日至2014年5月15日对四川省华蓥山自然保护区鸟类组成进行了调查.共记录鸟类有15目42科132种,分别占四川省鸟类21目80科683种的71.43%、52.50%和19.33%,保护区鸟类具有较高的多样性.其中,非雀形目鸟类47种,占保护区鸟类总数的35.61%;雀形目鸟类85种,占64.39%,以雀形目鸟类占优势.在保护区内有国家Ⅱ级重点保护鸟类12种,占四川省国家级保护鸟类11.22%.从物种的居留类型上看,在132种鸟类中,留鸟和夏候鸟最多,分别占保护区鸟类总数的56.06%和29.55%.在鸟类区系上,东洋界种类最多,占总数的55.30%;其次是古北界鸟类,占总数的28.03%.从分布型上看,以东洋型的种类最多,占总数的35.61%;其次是古北型,占总数的16.67%;分布最少的是东北-华北型和季风型,都仅为2种.通过相关的调查和比较,表明本区鸟类具有较高的丰富性.

The paper analyzes bird diversity in Sichuan Huaying Mountain Nature Reserve ,with field surveys con- ducted with the method of fixed transect lines. A total of 15 orders,42 families, 132species of birds were recorded, and they accounted for 71.43% , 52.50% and 19.33% of birds in Sichuan province, respectively. Protected areas have a high diversity of birds. Among them the non-passerine birds are 47, which account for 35.61% of total spe- cies; passerine birds are 85, which account for 64.39% of total species, description of passerine birds dominant. 12 species are listed in the second category of the nationally protected wildlife species, which account for 11.22% of the nationally protected birds in Sichuan. Residents and winter migrants are the most abundant species, which ac- count for 56.06% and 29.55% of total number of birds reserve , in 132 species,respectively. In term of avifauna, oriental elements, accounting for 55. 30% , are the most common species, followed by palaearctic elements （28.03%）. In term of profile, oriental type, accounting for 35.61% , is the most common species, followed by Gubei type （16.67%） , the least being Northeast-North China and Monsoon type. Through the relevant survey and comparison, this nature reserve has the relatively high bird species.
