摘要/Abstract

摘要： 2000年和2001年的4～7月,在内蒙古自治区科尔沁右翼前旗东南部的草原地带,采用样方法研究了火烧地和非火烧地上繁殖期大鸨的觅食地选择.结果表明,在火烧地和非火烧地,大鸨觅食地的植株高度均为13cm左右,最高高度不超过30cm,植被结构上具有共性;植物种类丰盛密集,盖度较大,喜食的植物和昆虫丰富.但在喜食食物选择上,火烧对大鸨有一定影响.在非火烧地,大鸨多关注动物性食物的丰盛;而在火烧地则关注植物性食物的丰盛.

Abstract: From April to July of 2000 and 2001,the authors studied the foraging habitat selection of Otis tarda dybowskil in the southeast Keerqin of Inner Mongolia by sampling method.The results showed that whether at burned or at non burned grassland,the foraging habitat of Otis tarda dybowski had the same feature in vegetation structure,the plant height was about 13 cm on average,with the highest of 30 cm,and there were abundant species of plants and insects with big density that the bird favored to eat.The bird more concerned with the abundance of plants at burned grassland,while that of insects at non burned grassland.

Key words: Otis tarda dybowskil, Breeding season, Foraging habitat, Habitat selection, Grassland
