Autumn Foraging-sites Selection of Brown-eared Pheasant in Huanglong Mountain Nature Couservation, Shaanxi Province
摘要
Abstract
The autumn foraging habitat selection of brown-eared pheasant ( Crossoptilon mantchuricum) in Huanglong Mountain nature conservation, Shaanxi Province, is studied, from October to November in 2006. The analyses show that foraging habitats are characterized by coniferous and broadleaved forest, altitude( 1 200 ～ 1 400 m ), slope degree( ＜ 10°), mid slope location, gully, arboreous cover(50％ ～80％ ), arboreous hight( ＜ 10 m), arboreous density ( ＜ 0.1/m2), and shrub cover( ＜ 30％ ), and shrub height ( ＞ 1.5 m) and shrub density( ＜ 1/m2 ), and herbaceous cover( ＜ 30％ ), herbaceous height( ＜ 16 cm), sheltering class( ＜ 10％ ),distance to water source( ＜500 m), edge of woods( ＜ 100 m) and human disturbance( 100 ～300 m). The main component analysis shows that there are four factors affecting the habitat selection of brown eared-pheasant. They are classified as factors of geography and herbage( altitude, cover and average height of herbs, geographical characters and slope location) , sheltering factor( cover, height and density of shrub and sheltering class), disturbance factor( distance to water source, edge of woods and human disturbance and vegetation type), and food factor( average diameter, cover, average hight, and density of arbores).关键词
