摘要
2018~2020年,每年1月份在涨渡湖湿地采用分区直接计数法和定点观察法对越冬水鸟多样性组成特征及影响因素进行了同步调查和研究。共记录水鸟43种,隶属于7目,9科,其中鸭科种类最多,鹭科次之,绝对优势种为红嘴鸥。不同年份间水鸟物种数和数量存在一定的波动。涨渡湖湿地湖泊冬季人工蓄水导致的高水位对自然滩涂的影响,鱼塘与湖泊水系缺乏水文联系产生的湿地生境斑块化,以及个别区域人与鸟的冲突是涨渡湖湿地鸟类多样性面临的三大主要影响因子。
The diversity and impact factor of wintering waterbirds in Zhangdu Lake were investigated from January 2018 to January 2020.A total of 43 waterbird species belonging to nine families and seven orders were observed by the partition direct counting methods and the fixed-point observation.The number of species and individuals varied between years.However,Anatidae was always the family contains the largest number of species each year,followed by Ardeidae,and the absolute dominant specie was Larus ridibundus.We also summarized three factors affecting the waterbird diversity in Zhangdu Lake,including the high water level due to the artificial water storage in the winter,the patchy habitat?of wetland caused by the lack of hydrological connection between the fish pond and the lake water system,and the conflict between people and birds.
