摘要
2006年-2009年来,笔者对陕西黄河湿地省级自然保护区内大鸨活动的栖息地范围、面积、大鸨种群数量以及植被等情况进行了调查分析,结果表明大鸨活动范围及除受食食物来源影响外还与人类活动等情况相关,但食物因素对大鸨的分布影响最大。
Investigations on Otis tarda activities around the wetland of Yellow River within Shaanxi was carried out in terms of the birds habitats,area,species quantities as well as the vegetations.The result shows that the area needed for the bird living is also influenced by human activities except for the food source.
