摘要
为了研究朱鹮巢址的生境特征,2013年4-7月,在陕西朱鹮国家级自然保护区外围的调查中共获得11个朱鹮弃巢和18个繁殖成功巢的生境数据。采用Mann-Whitney U-test检验弃巢和繁殖成功巢生境的差异性,结果显示两者在距道路距离、巢树种数、坡度等变量上具有显著差异,说明人类干扰可能是朱鹮弃巢的重要原因。因此,在保护区外围加强对巢树的保护,对于朱鹮种群的增长将具有重要意义。
To study the characteristics of abandoned nests of crested ibis, we investigated the habitat factors of abandoned nests and successful breeding nests of a dispersing population outside Crested Ibis National Nature Reserve in Shaanxi Province （China） from April to July in 2013. We obtained the habitat factors from 11 abandoned nests and 18 successful breeding nests of crested ibis. Mann-Whitney U-test was used to test the differences of the habitat factors between the abandoned nests and successful breeding nests. The results showed that the abandoned nest was significant different on the distance to road, number of nest trees and slope from that of the successful breeding nests. The results indicated that human disturbance might be an important factor for crested ibis to abandon the nest. Therefore, intensifying the conserving nest trees would be effective for the population increase of dispersing crested ibis outside Crested Ibis National Nature Reserve.
