摘要
1996年3～5月份．在扎龙保护区的核心区内进行了丹顶鹤的巢址选择的研究。结果表明：芦苇沼泽植被类型、水深、植被的高度和盖度、苇丛的面积及人为干扰等因素均影响丹顶鹤对巢址的选择。研究中还发现．巢址周围25m2以下的小泡沼、巢址与火烧地的距离同丹顶鹤的巢址选择有极为密切的关系．是重要的限制因子。
From March to May 1996, the selection of nest-site of red-crowned crane (Grus japonensis ) wasstudied in the core of the Zhalong Nature Reserve. The results showed that reed-marsh, water depth,vegetation height, vegetation cover' the area of, reed island and human disturbance are importantfactors affecting the nest-site selection of the red-crowned cranes. The existence of the ponds (< 25 m2)near the nest-site and the distance to burned field are closely related to the selection of nest-site ofred-crowned cranes.
