摘　　要：为了累积青头潜鸭栖息地适宜性方面的保护生物学信息,并为后续的迁地保护饲养繁育提供野外理论基础,基于最大熵(Maxent)模型,对河南民权黄河故道国家湿地公园青头潜鸭的越冬栖息地适宜性进行了分析与评价.结果表明:民权湿地公园内青头潜鸭适宜的越冬栖息地面积较小,仅占该区域总面积的4.66%,多集中于废弃鱼、藕塘等隐蔽性较好、食物较充足的小生境水域.应通过合理设置禁渔期、设立禁渔区、减少或杜绝人为干扰等,加强对该区域青头潜鸭的保护管理工作.The Baer s Pochard is a globally endangered bird species.Its population size is not optimistic and its known habitat is limited.In order to accumulate protection biology information on the habitat suitability of the Baer s Pochard,to provide a field theory basis for the subsequent ex situ conservation and breeding,from November to December 2018,analyzed and evaluated the suitability of overwintering habitat of the Baer s Pochard in the National Wetland Park of the Henan Minquan Yellow River.The results show that:the suitability of Baer s Pochard in the Minquan wetland park is relatively small,accounting for 4.66%of the total area.It is concentrated in small habitats such as abandoned fish ponds and ponds with good concealment and adequate food.In order to maintain the population of Baer s Pochard and the stability of their habitat quality and promote the subsequent ex-situ conservation and breeding,it is recommended that the relevant management departments should strengthen the protection and management of Baer s Pochard in the region.For example,setting up a closed fishing season,establishing a closed fishing area,reducing or eliminating human disturbances,etc.
