Abstract
2009年3-5月,在黄河三角洲保护区,运用Vanderploeg和Scavia选择指数和资源选择函数对25个东方白鹳巢址的利用进行了研究.结果表明:东方白鹳偏好选择在芦苇沼泽中的电线杆上筑巢,巢区水面比例较大,样方内水深度>15cm,植被较高,盖度较大,植被密度200-500根/m2,巢址距明水面、芦苇沼泽、树林距离较近,明水面深度<0.5m,距离人为干扰、农田、草地较远.东方白鹳巢址利用的资源选择函数为:logist(p)=-0.206-2.773×距明水面距离+2.200×距公路距离+1.444×距轻度干扰地距离+1.205×距草地距离+1.191×植被密度,模型正确率:88.6%,R2=0.721.食物、人为干扰和植被密度是影响东方白鹳巢址利用的主要因素
