摘要
2002年、2003年和2004年的12月至3月,在小兴安岭黑河胜山林场开展了驼鹿生境选择的研究。研究中选择了9类与驼鹿生境选择相关的生态因子:植被型、离公路距离、离采伐点距离、平均雪深、隐蔽程度、坡向、坡位、坡度、海拔,运用SPSS软件进行交叉汇总定量分析。结果表明,胜山驼鹿冬季以落叶阔叶林、灌丛为主要生境,影响驼鹿分布的主要生态因子为隐蔽程度、坡位,其次为雪深、坡向、离采伐点距离、离公路距离,坡度、海拔对驼鹿分布的影响不明显。
Winter habitat selection by moose was studied at Shengshan Forestry Center, the Lesser Khingan Mountains from 2002 to 2004 in October to March. Nine ecological factors including vegetation types, distance from mad, distance from cut site, average snow depth, sheltering class, slope aspect, slope, slope position and elevation associated with habitat selection by moose were selected. SPSS software was used to analyze the influence of above factors on winter habitat selection. The results showed that the moose preferred deciduous broadleaved forest and shrub. Among nine ecological factors, sheltering class and slope position were relevant significant. The next factors were snow depth, slope aspect, distance from cut site and distance from road. The impact of slope and elevation to moose distribution were not obvious.
