| 摘 要： | 2014年和2017年冬季,将红碱淖湿地原遗鸥繁殖湖心岛D、E半岛分别进行分割,使其重新修复成4个湖心岛。结果表明:2015年D岛成功繁殖200余巢,2018年和2019年分别成功繁殖2 600余巢、2 700余巢。2018年恢复后的E岛遗鸥尝试性筑巢几十巢,2019年成功繁殖遗鸥800余巢。通过湖心岛的生境修复,扩大了适宜遗鸥繁殖的湖心岛数量和面积,红碱淖遗鸥繁殖种群的数量明显增加,有助于缓解因湖心岛减少导致遗鸥繁殖数量承载力不足的问题,为实现红碱淖遗鸥繁殖种群的恢复和有效保护提供科学依据。

| Abstract: | In winter of 2014 and 2017,the lake-center island of Hongjiannao wetland for relict gull breeding was separated into halves of D and E,reforming them into 4 islets again.The results showed that the relict gulls select nesting once again on the restored islets.In 2015,more than 200 nests were successfully bred on D islet,and in 2018 and 2019,more than 2600 nests and 2700 nests were successfully bred,respectively.The relict gulls tried to build dozens of nests on the restored E islet,in 2019,more than 800 nests were successfully bred.Number and size of suitable islets were expanded through habitat restoration,which significantly increased the breeding population of the relict gulls.It helps to relieve the decreased reproductive carrying capacity caused by the decrease of islets,and it provides a scientific basis and guidance for the restoration and effective protection of breeding population of the relict gulls in Hongjiannao wetland. |
