无量山国家级自然保护区南涧片区中华鬣羚的群落环境研究
Analysis on the Community Enviroment of the Chinese Serow in the Nanjian area of Wuliangshan National Nature Reserve

摘要: 基于2019年11月至2021年1月在无量山国家级自然保护区南涧片区布设的红外相机数据,通过空间关联方法构建中华鬣羚地栖鸟兽关联网络,探讨中华鬣羚在群落中的生态学作用及其保护问题。结果表明:共记录了28种地栖鸟兽,鼠科动物与18种动物构成无量山保护区南涧片区物种关联网络,中华鬣羚在网络中与黄喉貂、马来豪猪、白鹇、印支灰叶猴、果子狸、红腹角雉产生直接空间关联。中华鬣羚与马来豪猪、红腹角雉、果子狸存在竞争关系, 3个物种种群过度增长可能排挤中华鬣羚的生存空间,影响中华鬣羚的种群发展。黄喉貂与中华鬣羚存在捕食关系,前者种群数量过大或过度增长可能抑制中华鬣羚的种群发展;中华鬣羚与印支灰叶猴、白鹇存在偏利关系并获益,对二者的保护可能促进中华鬣羚的发展。研究发现,中华鬣羚对于群落有重要的维持作用,建议对中华鬣羚进行长期监测,划分核心分布区,并采取措施维护和恢复其栖息地。Abstract: This study analyzed infrared camera data collected between November 2019 and January 2021 in the Nanjian region of Wuliangshan National Nature Reserve. Using spatial association methods, a species association network was constructed for the Chinese serow (Capricornis milneedwardsi) and other ground-dwelling birds and mammals to investigate the ecological role of the Chinese serow within the community and its community conservation issue. The results showed that a total of 28 ground-dwelling birds and animals were recorded. Murids and 18 of these animals formed a species association network in the Nanjian region of Wuliangshan National Nature Reserve. In this network, Chinese serow had direct spatial associations with Yellow-throated marten (Martes flavigula), Malayan Porcupine (Hystrix brachyura), Silver pheasant (Lophura nycthemera), Indochinese Gray langur (Trachypithecus crepusculus), Masked Palm civet (Paguma larvata), and Temminck's tragopan (Tragopan temminckii) in the network. Competitive interactions were identified between the Chinese serow and the Malayan porcupine, Temminck's tragopan, and Masked Palm civet, indicating that excessive population growth of these species may compress the habitat of the Chinese serow and inhibit the population development of the Chinese serow. A predator-prey relationship was observed between the Yellow-throated marten and the Chinese serow, suggesting that increased predator populations may further constrain the Chinese serow population. Conversely, the Chinese serow with the Indochinese Gray langur and the silver pheasant had commensal relationships, implying potential benefits to the Chinese serow through the conservation of these species. The study found that the Chinese serow played a crucial role in maintaining community structure. It is recommended to establish long-term monitoring of the Chinese serow, delineate core distribution areas, and implement measures to preserve and restore its habitats.
