江西新聞客戶端訊(江西日報全媒體記者洪懷峰)11月7日,記者從江西省生態學會獲悉,最新一期的《生態學報》刊發了一份越冬白鶴種群調查報告。該報告顯示,在我國越冬白鶴數量已達5616只,這一數據刷新了世界自然保護聯盟對白鶴數量的最高紀錄。

白鶴是中國一級保護動物。世界自然保護聯盟把白鶴列入了極度瀕危物種,對外公布全球的白鶴種群數量為3500至4000只。為查明全球白鶴在我國的越冬分布、種群數量及種群中的幼鳥比例,北京林業大學自2021年12月至2022年2月,聯合江西、山東、安徽、湖南、湖北等地開展了一次越冬白鶴調查。此次越冬白鶴調查統計結果顯示,全球白鶴在我國越冬數量達5616只,白鶴種群中幼鳥的比例達14.27%。其中,鄱陽湖記錄到越冬白鶴4813只,占總數的85.7%,主要分布在康山墾殖場、五星墾殖場和成新墾殖場。山東黃河三角洲記錄到越冬白鶴625只,占總數的11.1%。安徽、湖南、湖北分別記錄到越冬白鶴34、63和72只。

江西省生態學會副理事長兼秘書長、江西省科學院研究員戴年華表示,白鶴通常棲息于開闊沼澤草地、苔原沼澤和寬闊的湖泊邊沿及淺水沼澤地帶,是濕地中的旗艦物種,被看作是當地濕地生態處于相對平衡穩定、環境保護良好的一項重要標志。白鶴在全球原有東、中、西三條遷徙路線,由于受到濕地喪失,人為活動干擾等因素影響,目前只剩下前往鄱陽湖區越冬的東部遷徙路線。此次越冬白鶴種群調查,不僅記錄的全球白鶴種群數量刷新了歷史紀錄,而且發現白鶴“生活圈”不斷延展,分布區域開始呈多點擴散趨勢,證實了山東黃河三角洲是目前除鄱陽湖外最重要的白鶴越冬地,緩解了白鶴越冬期過度集中在鄱陽湖的壓力。值得一提的是,記錄到的5616只白鶴當中,幼鳥的比例達到14.27%。研究表明,白鶴種群中幼鳥的比例超過10%,說明白鶴種群的發展趨勢良好。這不僅是江西生物多樣性保護工作取得扎實成效,不斷推進高質量生態文明建設的重要見證,也是新時代中國生態文明建設取得巨大成就的生動寫照。
