摘要
草食性成鸟和幼鸟由于在冬季面临不同的生存压力和生理需求,因此不同越冬阶段对植物的利用也存在差异,对其差异性进行研究将有利于加强鸟类的保护与管理。以三门峡库区大天鹅越冬种群为研究对象,利用卫星跟踪的方法,分析了越冬成幼大天鹅对植被利用的差异性。结果表明,在河南三门峡天鹅湖湿地公园,大天鹅成鸟在10月和次年1月对可利用植被区域的利用低于幼鸟,其余月份均高于幼鸟;在山西平陆三湾,成鸟在12月至次年1月对可利用植被区域的利用低于幼鸟,在2月至3月高于幼鸟;在整个越冬期,在山西圣天湖成鸟对可利用植被的利用均高于幼鸟。成鸟和幼鸟在不同地点对植被的利用的差异与当地植物类型和自身的生理需求有关。
Due to the different survival pressures and physiological needs faced by adult and young herbivorous birds in winter,utilization of vegetation are varied with different wintering stages,and studying their differences will contribute to strengthen the protection and management of birds.In this paper,the differences in vegetation utilization of wintering whooper swans in the Sanmenxia Reservoir area were analyzed by satellite tracking.The results showed that the adult swans used less available vegetation areas at Sanmenxia Swan Lake Wetland Park of Henna in October and January than young swans,while higher than the young birds in the other months.At Sanwan of Pinglu,Shanxi,adult swans use less available vegetation area than juveniles from December to January and higher than juveniles from February to March.During whole wintering period,the use of available vegetation by adult swans in Shengtian Lake,Shanxi,was higher than that of young swans.The use of available vegetation by adult and young swans in different wintering sites was related to vegetation types and physiological needs of swans.
