四川美姑、汉源黑颈鹤迁徙停歇地环境调查

Habitat Survey to Stop-over Sites of Black-necked Cranes in Hanyuan and Meigu of Sichuan

于2005年及2006年春季在云南大山包和贵州草海给8只黑颈鹤（Grus nigricollis）放置了卫星发射器,观察结果表明,其中6只黑颈鹤至少完成了一次完整的春季或秋季迁徙。黑颈鹤在四川省汉源停歇的乡镇包括：乌斯河镇、河南、坭美、梨园、宜东、三交坪和皇木;在美姑停歇的乡镇包括：柳洪、依果觉、农作、拉木阿觉、炳途、瓦古、峨曲古龙门和尼哈。2005年6月4-8日和2006年6月8-14日实地考察了汉源和美姑两县的黑颈鹤停歇地点。黑颈鹤在两县的停歇地点都在海拔1900m以上且人为活动稀少的区域,或为草甸覆盖的高山浑圆山头,或为高山缓坡的林间空旷草地。

Eight Black-necked Cranes （Grus nigricollis） were banded with satellite transmitters in the spring of 2005 and 2006 at Dashanbao in Yunnan and Caohai in Guizhou. Six of the banded cranes completed at least one migration between their wintering and breeding grounds. Townships where these birds stopped over include： Wusihe, Henan, Nimei, Liyuan, Yidong, Sanjiaoping, and Huangmu in Hanyuan County, and Liuhong, Yiguojie, Nongzuo, Lamuajue, Bingtu, Wagu, Equgulongmen, and Niha in Meigu County. We surveyed stop-over sites in Hanyuan and Meigu Counties in Sichuan Province from 4 - 8 June 2005 and 8 - 14 June 2006. Stop-over sites in these two counties were all located in remote areas, more than 1 900 meters above sea level, either on hill tops covered by grass or open areas in the forest on the hillside.
