四川省甘洛县鸟类多样性

Bird Diversity in Ganluo County,Sichuan

甘洛县位于四川省凉山彝族自治州北部的小相岭山系,有丰富的鸟类多样性,但长期以来缺少鸟类基础调查资料。为了解甘洛县的鸟类多样性,本研究于2018—2021年采用样线法和红外相机陷阱法进行了调查。结合调查数据和历史资料,甘洛县鸟类共计有15目52科263种,其中,国家一级重点保护鸟类4种,国家二级重点保护鸟类38种;列入濒危野生动植物种国际贸易公约(CITES)附录Ⅰ4种,附录Ⅱ16种。8种生境类型中鸟类多样性最高的是常绿与落叶阔叶混交林,其次是灌丛,草甸最低;鸟类多样性垂直分布呈中峰模式,峰值出现在海拔1660~1940 m。本研究丰富了甘洛县和凉山山系的鸟类多样性数据,为当地生物多样性保护提供了参考。由于该地区鸟类基础调查研究薄弱又位于黑颈鹤Grus nigricollis迁徙路线,后续应加强珍稀雉类、夜行性和迁徙鸟类的调查和研究。

Ganluo County is located in the Xiaoxiangling Mountains in the north of Liangshan Yi Autonomous Prefecture,Sichuan Province.To enrich the basic information of bird resource in this area,the bird diversity was surveyed by using the sample line method and infrared camera method from 2018 to 2021.Combined the survey data and historical data,263 species belonging to 52 families and 15 orders were identified.There were 4 classⅠand 38 classⅡnationally key protected birds,and 4 species were listed in AppendixⅠof the CITES and 16 were listed in AppendixⅡ.Among the 8 habitats,evergreen deciduous broadleaved mixed forest had the highest bird diversity,followed by shrub,while meadow had the lowest;the vertical distribution pattern of bird diversity showed a medium peak pattern,and the peak value appeared at the elevations of 1660-1940 m.This study enriches the bird data of Ganluo County and Liangshan Mountains,and provides a reference for further protection of biodiversity in the area.Moreover,given that the studied area is located in the black-necked crane(Grus nigricollis)migration route with shallow basic information of birds,the investigation and research of precious Phasianidae,nocturnal and migratory birds should be strengthened.
