摘 要:2007年4月至2009年8月对牡丹江的雁鸭类资源,主要采用固定路线踏查法和定点样方法等形式进行了详细的调查,共记录雁鸭类17种,绿头鸭为优势种,占全部雁鸭类总数量的38.700%;中华秋沙鸭稀少,仅占总数量的0.081%。其中旅鸟5种,夏候鸟11种,分别占总种数的29.4%、70.6%。在居留型上,以夏候鸟为主。在区系组成上,古北种9种,占总种数的52.9%;广布种8种,占总种数的47.1%。本地繁殖鸟3种。调查发现,雁鸭类分布与生境关系非常密切,在以湿地和河道为主的生境中雁鸭类数量较大,人类活动和食物资源的变化也是造成分布差异的一个主要原因。The resources of geese and ducks in Mudanjiang were investigated in detail from April of 2007 to August of 2009 by using the route survey and quadrat method.17 species of geese and ducks were recorded.Anas platyrhynchos was the dominant species,accounting for 38.700% of total amount of geese and ducks.Mergus squamatus was the rare species,only accounting for 0.081%.5 species were passing migrants and 11 species were summer residents,which occupied 29.4% and 70.6% of total respectively.The fauna component analysis showed that 9 species were palaearctic species(52.9%) and 8 species were cosmopolitan species(47.1%).Three species were the local breeding birds.The investigation results showed that there was a close relationship between the distribution of geese and ducks and the habitat.The amount of geese and ducks in the habitats of wetland and river channel was larger.The change of human activity and food resources was one of the main reasons that caused the distribution difference.
