【摘要】 于2008年秋季应用样方法对陕西宁陕县寨沟野化放飞朱鹮(Nipponia nippon)的觅食地和食物丰富度进行了调查。结果表明,朱鹮秋季的主要觅食地是冬水田,影响朱鹮觅食地选择的主要因素是人为干扰、觅食地开阔度和土壤松软程度;宁陕野化放飞区朱鹮觅食地中共发现记录动物36种,冬水田翻耕对朱鹮的食物丰富度和生物量无显著影响。总体上,在秋季游荡期朱鹮的食物并不丰富。更多还原

【Abstract】 A survey about the feeding sites and food abundance of feralized Crested Ibis (Nipponia nippon) was carried out from September to November in autumn 2008 in Ningshan Shaanxi by using plot methods.The result showed that the paddy fields are main feeding sites of crested ibis.The factors that affected the food site selection were human disturbance,the degree of width and softness of soil.36 species were collected and identified in the feeding sites,and field furrowing had no significant effect on food abundance and food biomass.In general,the food was not abundant for crested ibis in autumn wandering stage in the area.更多还原
