大庆龙凤湿地春季鸟类多样性研究

大庆龙凤湿地在动物地理区划分上属于古北界,本次调查在其保护区内共发现鸟类71种,隶属10目27科,其中国家Ⅰ级保护动物3种,Ⅱ级保护动物11种,调查仅限于春季,一些保护区曾经出现过的国家珍稀保护动物没有被发现。由于保护区有大面积湿地,所以水禽种类占大多数,且数量众多。鸟类组成以夏候鸟为主,种类有42种,占总数的59.15%。本次调查中,古北界鸟类54种,占总数的76.06%;广布种17种,占总数的23.94%;没有东洋界鸟类的入侵。很多鸟类从这里迁徙和经过,且以古北区的鸟类为主。本次调查采用样带、样点和定点观察法,对保护区内的鸟类种类和数量做了调查统计,并分析出近几年来这里鸟类种类数量减少的原因。

Spring Bird Diversity in Longfeng Wetland of Daqing

The geographic region of Daqing Longfeng Wetland is Palaearctic.In this survey,we recorded 71 species,10 orders and 27 families of birds in the protected area.Among the 71 species,3 are listed as first-class nationally protected animals,and 11 were listed as second-class.Because this survey was conducted only in spring,some previously reported national rare and protected animals were not recorded.Because there are large areas of wetlands in the protected area,most recorded birds were waterfowls.Large numbers of birds in this region were summer migrants,of which we recorded 42 species accounting for 59.15%of total records.Fifty-four species of birds were Palaearctic,accounting for 76.06%of all species.Seventeen species were widely distributed and accounted for 23.94%of all records.We recorded no Oriental species invasion although many migrating Oriental species passed through this area.Dominant species were Palaearctic.We conducted the survey using transect,sample point and fixed-point observation method.We recorded the number and species of the bird in protected areas,and analyzed the reason for the reduction of bird species in recent years.
