【摘要】2009年11月至2010年4月对云南省香格里拉县纳帕海省级自然保护
区越冬黑颈鹤(Grus nigricollis)的夜栖地的特征进行了调查.采用三角定位标图结合标志物校正法确定夜栖地方位,并进行实地校正.共记录夜栖地63个,均位于有水的
斑块状沼泽中,基底大多有泥层,大部分(81.0%)有植被覆盖.夜栖地与人类活动区域
和沼泽岸边有一定距离.与随机对照样地相比,夜栖地基底泥层较厚(Z=-
2.365,P=0.018),明水面比例较大(Z=-
3.086,P=0.002),离道路、村庄和农田较远(Z/t=-2.852～-2.334,P=0.008～0.020),水深在两者间有极显著差异
(χ2=16.730,P=0.001).夜栖地利用前后对比发现沼泽斑块的面积有显著差异
(t=2.977,P=0.021).主成分分析表明影响黑颈鹤夜栖地利用的因素依次为人类干扰、沼泽斑块大小和浅水环境状况.%From November 2009 to April 2010,
roosting-site characteristics of black-necked cranes (Grus nigricollis) were observed at Napahai Provincial Nature Reserve, Shangri-La, Yunnan, China. The positions of roosting-sites were determined by triangulation with markers and field correction. All of the 63 roosting-sites observed were located inpatchy marshes with water, which contained some mud on the bottom and 81％ of the roosting-sites were covered by plants. They also had a certain distance to areas of human activities and had a certain distance to the shore. A comparison of roosting sites and random sites
showed that roosting-sites had thicker mud layers, a higher ratio of open water, longer distance to roads, villages, and farmland, and water depth. Another comparison of before and after usage of roosting-sites found a significant difference in area of marsh patch. Principal component analysis indicated that the usage of roosting-site of black-necked cranes was affected by human disturbance, area of marsh patch, and the condition of the shallow water environment.
