拉萨藏雪鸡春季栖息地选择

2005年3—4月,在拉萨曲水县雄色寺周围山上的灌丛地,对藏雪鸡栖息地选择,通过调查和测量与其有关的14个参数,发现雪鸡喜欢在灌丛盖度较低、距离民居近的地方觅食,并喜欢在灌丛盖度较低、草本种类较少、草本盖度较低、岩石较多、距民房距离较近的地方休息。另外还发现,人类保护和投食对雪鸡栖息地选择也有很大的影响。调查结果显示,研究地区的雪鸡活动在很大程度上依赖人类活动。

Habitat Selection of Tibetan Snow Cocks in Spring in Lhasa

Habitat selection of Tibetan Snow Cocks in shrub vegetation was investigated in Lhasa, Tibet during March and April of 2005. Fourteen parameters have been measured, including: altitude, slope, slope aspect, position on slope, vegetation cover, plant type and other environmental parameters. The results showed that Snow Cocks like foraging in areas where the vegetation cover is small and close to residents' houses;Snow Cocks like roosting in areas where the vegetation coverage is low, grass types are few, the cover of grasses is low, with large rocks and close to residents' houses. From the results we found that the activities of Snow Cocks in research areas rely on human activities.
