摘要
2012年3～5月，在六盘山国家级自然保护区对野猪生境选择特征进行调查研究。共设置了33个10m×10m样方和18个生态因子。运用聚类分析和主成分分析的方法，对野猪生境进行了分析。结果表明：野猪偏好选择的生境为海拔2400～2800m、草本高度≤30am、草本覆盖度〉50％、无灌木（54．5％）、1m以下当年生枝比例高的温性针叶林和落叶阔叶林；对水源距离≤100m和人为干扰距离〉500m的生境有一定的选择性；对地理因子没有明显的偏好。
Habitat selection of the wild boar （ Sus scrofa ） was investigated from March to May 2012 in the Liupan Mountain national nature reserve. Eighteen ecological factors were recorded in each of the thirtythree 10 m ×10 m plots. The data thus were collected and analyzed using cluster analysis and principal component analysis. The results showed that wild boars preferred habitats with the following characteris- tics： altitudes of 2 400 - 2 800 m, height of herb less than 30 cm, cover of herb greater than 50%, no brash, high levels of the proportion of 1 m below the branches, distance to water source not greater than 100 m, distance to human disturbance less than 500 m. There were no obvious preferences low and geo- graphic factors for the animals.
