摘　　要：20 0 3年 3～ 4月 ,在甘肃省莲花山自然保护区 ,利用无线电遥测和直接观察 ,分析了斑尾榛鸡(Bonasasewerzowi)的栖息地选择特征。结果表明 ,斑尾榛鸡春季栖息地一般在东北坡向 ,并具有高大乔木、下层植被盖度较高、灌丛较丰富的特点 ,这与食物丰富度较高及环境隐蔽性较强有关。栖息地质量对于配对活动的成功与否有一定影响。分析表明 ,栖息地内 0 5～ 2 5m植被水平遮挡度、柳树数量、箭竹数量是影响斑尾榛鸡春季栖息地选择的关键因子。建议在对斑尾榛鸡栖息地采取保护措施时 ,不仅要保护原生乔木 ,还要加强对灌丛生境的保护。This study was conducted at the Lianhuashan Natural Reserve in Gansu province in March and April of 2003. The characteristics of spring habitat for Chinese Grouse (Bonasa sewerzowi) was analyzed by plot method and principal component analysis based on radio-tracking and direct observations. The results indicated that the Chinese Grouse preferred a habitat with better cover of shrubs and bigger spruces and firs, normally at northeastern slopes. It was mainly related to food abundance and vegetation cover for escaping from predators. Horizontal cover between 0.5 to 2.5 m above the ground, abundance of willows and arrow bamboos are the main factors influencing the spring habitat selection of the Chinese Grouse. It is suggested that it be necessary for the conservation of Chinese Grouse habitat to protect both arbors (spruce and fir) and shrubs (willows and arrow bamboos).
