摘　　要：四川沙鲁里山系南段地处横断山区,是我国和世界生物多样性保护的热点区域,具有重要的生态和生物多样性保护价值。2019年8月—2021年4月,对沙鲁里山系南段四川省境内8个县域的鸟类资源开展了野外调查,并结合历史资料,统计出鸟类20目68科467种。其中,国家重点保护野生鸟类92种,中国特有鸟类28种。在划分的7类生境(干旱河谷灌丛、针阔混交林、亚高山针叶林、高山灌丛草甸、亚冰雪稀疏灌丛、居民-农田和水域湿地)中,针阔混交林中的物种最丰富,水域湿地和亚冰雪稀疏灌丛中的最低。野外调查共观察到鸟类31739只,以水域湿地的数量最多(35.59%);亚冰雪稀疏灌丛的最少(1.25%)。各生境鸟类群落Shannon-Wiener指数为:亚高山针叶林>高山灌丛草甸>针阔混交林>干旱河谷灌丛>亚冰雪稀疏灌丛>居民-农田>水域湿地,亚高山针叶林与高山灌丛草甸的鸟类群落相似性最高(IsJ=0.50)。鸟类物种丰富度的垂直分布格局呈中峰模式:中海拔段(2800~3600 m)达到峰值。本研究丰富了该区域生物多样性本底信息,为区域整体保护和保护成效提升提供了科学依据。The southern section of Shaluli Mountains(SSSM)is located in the Hengduan Mountains,which is a hot area of biodiversity conservation in China and in the world,and has important ecological and biodiversity protection value.From August 2019 to April 2021,field surveys of bird resources were carried out in the SSSM that includes 8 counties of Sichuan Province.Combined with historical data,there were 467 bird species belonging to 68 families and 20 orders,accounting for 32.32%of the total number of bird species in China,and 92 species of wild birds were under national priority protection and 28 species were endemic to China.Among the 7 habitat types,including arid valley shrub,conifer-broadleaves mixed forests,subalpine coniferous forest,alpine scrub meaow,subice-snow sparse shrub,resident-farmlands and water wetland,coniferous and conifer-broadleaves mixed forests had the most abundant bird species,while water wetland and subice-snow sparse shrub had the lowest.A total of 31739 birds were observed in the field survey.The largest number of birds was observed in water wetlands,accounting for 35.59%of the total,and the lowest was observed in subice and snow sparse shrubs,accounting for only 1.25%.The order of Shannon-Wiener index of bird community in each habitat was subalpine coniferous forest>alpine shrub meadow>conifer-broadleaves mixed forests>arid valley shrub>subice-snow sparse shrub>resident-farmlands>water wetland.The bird community similarity between subalpine coniferous forest and alpine scrub meadow was the highest(IsJ=0.50).The vertical distribution pattern of bird species richness showed a middle peak pattern,and reached a peak at the middle pull-out section of 2800-3600 m asl.This study enriches the background information of regional biodiversity and provides a scientific basis for improving the overall conservation and protection effectiveness of the region.
