摘　　要：山东黄河三角洲国家级自然保护区是天鹅重要的迁徙停歇地及越冬场所,通过连续20年的动态监测显示,自然保护区内栖息的天鹅以大天鹅为主,秋、冬季节最为常见,秋季南迁大天鹅10月中旬陆续抵达黄河三角洲,种群达到2102只,自2014年以来,南迁大天鹅种群持续增加,2018年达到6559只。越冬期大天鹅种群平均达到506只,主要栖息在自然保护区内的湿地恢复区、黄河故道区、冬小麦农田区。近年来,自然保护区内实施了生态多样性保护工程、湿地保护与修复工程、外来入侵植物监测与防治工程,总投资达2.35亿元,为水鸟提供了良好的栖息环境,天鹅的种群数量整体呈增加的趋势,成为其重要的越冬地。The Yellow River Delta National Nature Reserve in Shandong Province is an important place for the migration and wintering of swans.According to the dynamic monitoring for 20 consecutive years,whooper swan was the main swan inhabited in the nature reserve,mainly appeared in the autumn and winter.The swans migrated southward successively arrived in the Yellow River Delta since the middle of October.The migrating population of whooper swans remained 2102 averagely and increased continuously,with a maximum population of 6559 in 2018.During the overwintering period,the average population of swans reached 506,which mainly inhabited in the wetland restoration area,the old channel area of the Yellow River and the winter wheat farmland area in the nature reserve.In recent years,ecological diversity protection project,wetland protection and restoration project,alien invasive plant monitoring and control project have been implemented in the nature reserve,with a total investment of 235 million yuan,providing a good habitat for water birds,and the population of swans is increasing as a whole.The reserve has become an important overwintering place for swans.
