摘要: 应用聚类分析的方法,对小兴安岭地区野猪冬季卧息地选择进行了研究。结果表明,对其影响的主要因子是人为干扰、坡向和隐蔽条件。其次是植被类型、食物丰盛度,坡度和水源。坡位和海拔也有一定影响。其最适卧息地生境条件的选择依次为:草甸沟塘或阔叶林植被,食物丰盛度中等以上,隐蔽级≥0.5,阳坡,卧息地距人为干扰源>1000m和距水源≤1000m。

Abstract: we studied winter bedding site selection of ussurian wild pig in the lesser Khing-an Mountains during 1985- 1987 .On the basis of analysis of field data using the Cluster Analysis,the results showed that the ultimate factors which exerted notable influence on winter bedding she selection of wild pig were human disturbance,sheltering class and slope aspect;the proximate factors were vegetation type,food abundance and slope degree;the random factors were elevation and slope position. The optimal winter bedding site of ussorian wild pig were as follows:deciduous stand or meadow-stream bottom ;excellent or fair food abundance sunny slope; sheltering class≥ 0.5;distance from human disturbance> 1 000m ;distance fram water source≤ 1 000m.
