摘 要: | 2002~2004年3~8月,在扎龙国家级自然保护区,通过定点观察法、样方法、因子测定法等对丹顶鹤育雏期的生境选择进行了研究,旨在为丹顶鹤种群的有效保护提供基础资料。结果表明:扎龙保护区,育雏期不同阶段丹顶鹤的育雏生境选择不同,育雏前期,丹顶鹤选择芦苇沼泽,仅局限于以巢址为中心的小范围内活动;育雏后期,丹顶鹤的育雏活动范围开始向外扩展甚至与巢址生境不同,偏爱于开阔度较大且能提供水和隐蔽的苔草沼泽。

Abstract: | In Zalong Nature Reserve,during 2002-2004,from March to August,habitat selection of the red-crowned crane in rearing their chicks was observed by fix-spot observation method,scan sampling method,focus sampling method,GPS positioning, plot sampling measurement and factor measurement.Results showed that in different stages of rearing,different habitats were selected: in the early stage,the reed marsh habitat was selected and their activity was restricted only in a small area around the nest as the cen- ter;in the later stage,their activity area was extended to habitats different from those of the nest area,preferring to select open Carex marsh with supply of water and better shelter. |
