云南纳帕海越冬黑颈鹤夜栖地特征
Roosting-site characteristics of wintering black-necked cranes (Grus nigricollis) at Napahai, Yunnan
摘要
Abstract
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.关键词
