摘　　要：目的:研究药用动物褐翅鸦鹃在广西的种群生存现状。方法:采用样线法对广西18个调查区进行调查,记录在野外观察到的褐翅鸦鹃种群数量、生境等生物学信息。结果:褐翅鸦鹃可见于全部调查区,种群密度呈自桂南向桂北减少的趋势。在7种生境类型中,褐翅鸦鹃偏好在林区-农田群落交错区分布和活动,而较少出现于阔叶林、人工林等生境中。结论:广西常见的林区-农田交错区生境需求有利于褐翅鸦鹃种群的恢复,但捕猎压力减缓了恢复速度,应加大宣传和保护力度。Objective ：To understand the population distribution, species abundance and habitats requirement of a medicinal animal, Centropus sinensis, in Guangxi Province. Methods：Line transect methods were used to census population number and habitat types in 18 counties or cities of Guangxi. Resuhs：Centropus sinensis distributed in all study area, with a higher population density in the south than in the north. Among seven habitat types, the species preferred living in forest-farmland ecotone, while seldom in broad-leaves forest or plantations. Conclusion：The results of habitat preference show an advantage to the population recovering for forest-farmland ecotone commonly existing in Guangxi Province. But the speed of population recovering is slowly under illegal hunting pressure. More attention should be paid to protect this species.
