黑龙江凤凰山自然保护区野猪秋季生境选择

为掌握黑龙江省凤凰山国家级自然保护区内野猪种群的空间分布现状与迁移规律,于2009年秋、冬两季,应用样线调查法和样方调查法对野猪的生境选择情况进行调查,结合Vanderloeg和Scavia选择系数(W1)与选择指数(Ei)分析评估野猪对15个生境因子的偏爱程度,用秩和检验方法比较了野猪选择样方与非选择样方的差异.结果...

Autumn habitat selection of wild boar in the Fenghuangshan Nature Reserve, Heilongjiang Province

The habitat quality of the wild boar (Sus scrofa) was investigated by transect and plot surveys in the Fenghuangshan Nature Reserve, Heilongjiang Province, in autumn and winter of 2009, to explore spatial distribution and migration patterns of this animal. Vanderloeg &; Scavia’s selectivity coefficient (Wi) and selectivity index (Ei) were used to assess the habitat factors that the wild boar preferred. Mann Whitey’s U test was used to explore the difference between samples selected and those neglected by the wild boar. The results showed that the wild boar tend to live in such habitats as mixed coniferous and broadleaf forests with abundant food supply, preferring half sunny / half shady slopes with lower slope position, gentle slope degree, moderate anthropogenic interference and high level vegetation cover, and avoiding habitats with steep slope, low level vegetation cover and severe disturbance. Four of the 13 given factors, food richness, level of concealment, slope gradient and slope position, were decisive for the wild boar’s utilization of habitats. In addition, the difference between samples selected and those avoided by the wild boar is significant (P < 0.05).
