摘　　要：为更好地保护玉门地区鸟类资源及栖息地，于2012年6月～2013年7月，对玉门鸟类的种类、数量、分布和生境进行了多次调查，获得了详细的鸟类资料．玉门地区共有鸟类79种，隶属15目，27科，54属，其中留鸟21种，夏候鸟43种，旅鸟15种，国家重点保护鸟类10种．鸟类区系以古北界成分为主，古北界种类46种，占繁殖鸟总数的71.9％，而东洋界鸟类仅2种．本研究还分析了自然环境变迁，尤其气候变干旱和人类活动对鸟类多样性及其种群数量的影响．The species , population and ecological distribution of the birds are investigated during the period from June 2012 to July 2013 . Along with the present documents ,79 species are recorded , which belong to 15 orders , 27 families and 54 genera . In them there are 21 residents , 43 summer migrants and 15 kinds of passing birds , including 10 species under state-grade protection . Palaeoarctic realm plays an important role in the avifauna , accounting for 71.9% of the breeding birds and only 2 species of oriental realm . However ,wetlands have been destroyed to different extents . The wetland in the desert area is ultimately developed into salt pond or desert . Important factors leading to desertification of wetlands are climate to transform into dry , irrational use of water resources and reclaiming land from marshes , resulted in considerable loss of bird diversity .
