摘要
为了探讨黑琴鸡越冬初期的生境选择策略,2006—2009年的10月中旬,利用样方法、因子测定法、卡方检验等方法对内蒙古红花尔基樟子松林国家级自然保护区的黑琴鸡越冬初期的生境选择进行了调查分析。研究结果表明：越冬初期,黑琴鸡觅食、栖息的生境具有以下特征：对草地—樟子松林和较开阔的草地选择性较高（75.4%）,海拔较低（多为700~800 m）,坡度在20°以下的中下坡位,而距离村镇的距离比较远,多在8~12 km,距公路的距离多大于2 km,而距林缘的距离则多选择在40 m以内。
To probe into the habitat selection strategies of the Black Grouse（Lyrurus tetrix）,a study on habitat selection by the Black Grouse was conducted in Honghuaerji Nature Reserve in mid-October of 2006-2009 by the methods of fixed-spot observation,GPS positioning,plot sampling measurement,factor analysis,chi-square test,and so on.Results show that in early winter,Black Grouse prefer grassland-Scotch pine forests and open grasslands,and the habitats are characterized by low elevation（700-800 m）,gentle slope（less than 20°）,middle and lower slope positions,far from village（8-12 km）,more than 2 km away from road,and less than 40 m from forest edge.
