中新社衡水8月1日电 (裴国荣 崔志平 张凯)河北衡水滨湖新区资源保护局1日消息，青头潜鸭人工繁育与野化放飞研究项目在衡水湖取得阶段性成果，成功建立世界首个稳定的青头潜鸭自然繁育种群，将为全球湿地生物多样性保护提供可复制、可推广的实践经验。
位于河北省衡水市的衡水湖面积75平方公里，是华北平原保持沼泽、水域、滩涂、草甸和林地等完整湿地生态系统的国家级自然保护区，也是东亚—澳大利西亚候鸟迁徙线上的重要驿站，同时是世界极危物种青头潜鸭在全球范围内的核心繁殖地与越冬地之一。
河北衡水滨湖新区资源保护局副局长张余广称，该项目由北京林业大学、北京动物园与河北衡水湖国家级自然保护区合作开展，经过两个完整繁殖期，不仅数量有巨大突破，并且积累了涵盖繁殖习性、栖息地需求的宝贵实践数据。
东亚—澳大利西亚迁飞区伙伴关系协定(EAAFP)青头潜鸭专家组主席、中国青头潜鸭保护与监测工作组组长丁长青介绍，基地内建设的野化训练网笼，严格参照野生青头潜鸭栖息地选择特征，模拟自然湿地植被结构、水域环境及食物链特征，为人工繁育个体提供了科学的野化训练环境。(完)
