摘　　要：灰胸薮鹛Liocichla omeiensis是我国西南山地特有的珍稀噪鹛科Leiothrichidae鸟类,国家一级重点保护野生动物。关于该鸟类的种群状况一直缺乏系统调查,导致该物种长期得不到有效的保护与管理。2018—2019年,对灰胸薮鹛的种群分布、数量及主要受胁因素开展了专项调查,发现6个新分布地,将其分布地扩大为18个县(区)。结果显示,灰胸薮鹛的平均密度为(1.68±0.43)♂/km^(2);栖息地破碎化、丧失和盗猎是灰胸薮鹛种群的主要受胁因素。当前应加大对灰胸薮鹛现有适宜栖息地的保护,同时加强宣传教育,严厉打击盗猎和贩卖野生鸟类;建议相关保护区开展植被恢复时,可考虑种植一些快速生长的本地竹类(如八月竹Chimonobambusa szechuanensis),以增加灰胸薮鹛的适宜栖息地面积。Emei Shan Liocichla(Liocichla omeiensis)is a rare babbler endemic to the Mountains of Southwest China,and has been listed as a nationally protected species in China.The lack of systematic investigation on population status has led to the long-term failure of effective protection and management of L.omeiensis.In order to develop an effective strategy for species conservation,surveys of L.omeiensis populations were carried out in 2018 and 2019.A total of six new distribution areas were identified.The updated distribution areas of L.omeiensis included 18 counties(districts).The survey results showed that the average population density of L.omeiensis in this survey was(1.68±0.43)♂/km^(2).Meanwhile,habitat fragmentation and loss as well as poaching were found to be the main threats to L.omeiensis population.Currently,it is necessary to increase the protection of existing suitable habitats for the babbler,strengthen publicity and education,and severely crack down on illegal poaching and trading of wild birds.Moreover,it is suggested that some fast-growing native bamboos(e.g.Chimonobambusa szechuanensis)should be planted in relevant nature reserves while carrying out vegetation restoration to increase the area of suitable habitats for L.omeiensis.
