江西武夷山国家级自然保护区脊椎动物资源调查编目(Ⅲ):鸟纲

Investigation and catalogue of vertebrate resources in Jiangxi Wuyishan National Nature Reserve(Ⅲ):Aves

截至2021年底,江西武夷山国家级自然保护区记录有鸟纲动物18目67科195属337种,其中常见物种19种,占5.64%;模式种(亚种)42种,占12.46%;中国特有种9种,占2.67%。中国受胁(CR/EN/VU)物种18种,近危物种(NT)28种,数据缺乏物种(DD)1种;IUCN受胁物种9种,近危种3种;国家重点保护野生动物65种;列入CITES附录I和附录Ⅱ的有32种;江西省重点保护野生动物43种。DG-F指数为0.884 7(DF=43.282 4,DG=4.991 5)。研究区单位面积内乔木数量、物种数和郁闭度,是影响鸟类多样性的关键因子;按物种构成可大致分为:低山农林营作干扰亚区(海拔900 m以下),次生性植被(过渡性)亚区(海拔900~1 400 m),山顶原始植被亚区(海拔1 400 m以上)3个分布梯度。研究区在中国鸟类区系中所处地位和作用有待深入研究。

By the end of 2021,337 species of 195 genera,67 families,18 orders were recorded in Jiangxi Wuyishan National Nature Reserve,including 19 common species(5.64%),42 type species(subspecies)(12.46%),and 9 endemic species(2.67%)in China.There were 18 threatened species(CR/EN/VU),28 species of near threatened species(NT),1 species of lack of data(DD),9 species of Red List IUCN threatened species,3 species of near threatened species,65 species under national key protection,32 species under CITES Appendix I and AppendixⅡ,and 43 species under key protection in Jiangxi Province.DGF index was 0.8847(DF=43.2824,DG=4.9915).It was the key factors affecting bird diversity which the number of trees,species and canopy density per unit area of the study area.According to the species composition,it could be roughly divided into three gradients:low mountain agroforestry disturbance subarea(below 900 m above sea level),secondary vegetation subarea(transitional vegetation subarea)(900-1400 m above sea level),and peak original vegetation subarea(above 1400 m above sea level).
