摘要
2011-2016年越冬期间,采用样点法和样线法相结合,对鄱阳湖区5个区域的52个样点进行了调查,共记录涉禽29种,隶属于2目5科。其中国家I级重点保护鸟类4种,国家Ⅱ级重点保护鸟类3种。研究结果表明,在空间分布上,涉禽的觅食生境、食性以及取食方式多样,从而实现生态位分化;在扩散能力上,一些数量等级低和濒危程度高的涉禽往往具有较高的扩散能力,也有例外,鸟类濒危程度与扩散能力的关系还有待进一步研究。
An investigation was carried out by line transect and point methods on 5 areas＇52 sampling points in Poyang Lake area during wintering period,from 2011 to 2016. A total of 29 wading species belonging to 5 families 2 orders were recorded. Among them,4 species belong to first class national key protected birds and 3 species belong to Second class national key protected birds. The results showed wading birds have different foraging habitats, feeding habits and feeding methods, to realized niche separation;on the dispersal ability, some wading birds with low quantity level and high endan- gered category always have a high dispersal abilities, but there are exceptions. So the relationship between endangered degree and disoersal ability needs further study.
