摘　　要：2002~2014年,对广西西南石灰岩地区的15个自然保护区、3片林区和2个水库共20个调查点进行了受胁鸟类调查。调查共记录了受胁鸟类90种,其中国家重点保护动物有60种,包括Ⅰ级1种、Ⅱ级59种;被列入IUCN红色名录的有21种,包括3种濒危(EN)、8种易危(VU)和10种近危种(NT);被列入《中国物种红色名录》的有40种,包括3种濒危(EN)、9种易危(VU)和28种近危(NT);被CITES附录收录的物种有45种,其中附录Ⅰ有2种,附录Ⅱ有43种。易危种、弄岗穗鹛为本地区的特有种。目前,对桂西南石灰岩地区的鸟类构成威胁的主要因素有非法狩猎,以及由毁林开荒、砍木烧炭、公路建设和桉树人工林的种植等导致的栖息地片断化和丧失。除了采取对应的保护措施,作者认为在保护策略上,应将分布有较多受胁种的2个调查点予以优先保护。下一步工作重点则是针对受胁鸟类进行更细致的分级评估,确定优先保护鸟种。From 2002 to 2014, ornithological surveys were conducted in 20 sites(fifteen nature reserves, three forest areas and two reservoirs) in the limestone area of southwestern Guangxi. In these 90 threatened bird species,60 species of birds were listed in Chinese National Key Protected Wild Animals(1 grade Ⅰ, 59 grade Ⅱ protected species), 21 globally threatened species were listed in the IUCN Red List(3 Endangered, 8 Vulnerable, 10 Near Threatened), 40 species were listed in the China Species Red List(3 Endangered, 9 Vulnerable, 28 Near Threatened),and 45 species of birds were listed in the CITES Appendix(2 AppendixⅠ, 43 Appendix Ⅱ). Vulnerable species,Stachyris nonggangensis, is endemic to southwestern Guangxi. At most of the sites, the main threats to these birds were poaching, habitat fragmentation and loss which caused by deforestation for farming and charcoal or road construction. Therefore, the conservation measures should be carried out as soon as possible. At the meantime, two research sites should deserve prior conservation for many threatened birds inhabit. Next, we will put effort on the work of evaluating prior conservation species among 90 threatened birds.
