扎龙湿地野生与散养白枕鹤繁殖前期觅食生境选择对比分析

为了探讨野生与散养白枕鹤（Grus vipio）觅食生境选择的异同，2004年春季，通过定点观察法、样方法、因子测定法对扎龙湿地二者繁殖前期的觅食生境选择作了对比研究。结果表明，繁殖前期，野生白枕鹤繁殖对觅食生境选择具有严格要求，倾向于选择人为活动较少（1．67km）、靠近明水面（21．0m）、剩余苇丛隐蔽度较高的苔草沼泽生境中觅食；散养白枕鹤对生境类型的要求不高，倾向于选择距人为活动区域较近（0．32km）的生境觅食。

Comparing of Feeding Habitat Selection between the Wild and Semi-domestic White-naped Crane during the Pre-breeding Period in Zhalong Wetland

To study the differences on feeding habitat selection between the wild and semi-domestic White-naped Crane (Grus vipio), a comparative research was conducted during the pre-breeding period in Zhalong Wetland in 2004. Fixed-spot observation, plot sampling and factors measurement were employed in this study. The results showed that during the pre-breeding period the wild White-naped Cranes have strong selection to the feeding habitats, they preferred to feed in the carex marsh with less human activity (1.67 km), closing to open water (21.0 m), and better shelter; and that the semi-domestic White-naped Cranes was less selection on feeding habitat, preferred feeding on site close to human activity (0.32 km).
