安徽屯溪三江省级湿地公园越冬水鸟时空分布动态

Temporal and Spatial Dynamics of Wintering Waterfowls for Tunxi Provincial Wetland Park in Huangshan City

针对安徽屯溪三江省级湿地公园不同生境的越冬水鸟,利用样点调查法,记录水鸟的种类和数量,研究水鸟在越冬期的分布动态。结果表明:安徽屯溪三江省级湿地公园是越冬水鸟重要的越冬场所,越冬水鸟在安徽屯溪三江省级湿地公园的不同地点(梅林湿地、湖边水利枢纽集水区、湖边水利枢纽尾水区、新潭水利枢纽集水区、新潭水利枢纽尾水区、广宇湿地)总数量共6191只,有36种。尽管不同地点和月份之间的水鸟种类、数量无明显差异,但仍表现出水利枢纽尾水区多于集水区,人为干扰较大的湿地鸟类较少;越冬中期(2020年12月和2021年1月)的水鸟数量和种类大于越冬初期(2020年10月和11月)和末期(2021年2月和翌年4月)。

The species and numbers of overwintering waterfowls in different habitats of Tunxi Provincial Wetland Park were recorded by using the sample survey method to study the distribution dynamics of waterfowls in the overwintering period.The results showed that the park was an important wintering habitat for wintering waterfowls,the total number of 6191 and 36 species for waterfowls in different sites(Meilin wetland,Hubian dam catchment area,Hubian dam tailwater area,Xintan dam catchment area,Xintan dam tailwater area,Guangyu wetland)at the wet-land park.Although no difference of the number and species between different sites and months,dam tailwater areas were more than dam catch-ment areas and the waterfowls’number and species were less in more human disturbance;The number and species of waterfowls in mid-winte-ring(December 2020 and January 2021)were greater than those in early winter(October and November 2020)and late winter(February 2021 and April 2022).
