摘 要 ：2005年6月至8月，在伏牛山北坡对野猪的泥浴场特征进行了研究。野外设置了42个20×20m2样方和14个生态因子，以此为基准运用聚类分析和主成分分析的方法，对野猪泥浴场进行了分析，结果表明，野猪泥浴场的生境特征为：（1）安全舒适因子：无倒木、无树桩、隐蔽距离30m以下、黄泥土质、郁闭度80%以上；（2）植被地形因子：乔木距离适中、灌木距离小于1m、坡度小于30°；（3）植被类型因子：高度倾向阔叶林；（4）干扰因子：人为干扰距离大于500 m；（5）海拔因子：海拔高度大于1000 m。在水源距离和坡位两项上没有明显的偏向。

Abstract:Mud bath sites of the wild boar (Sus scrofa) were investigated in June-August 2005 on the northern slope of Funiu Mountain.. Fourteen ecological factors (Vegetation type, Elevation, Slope, Location, Aspect, Distance to water source, level of concealment, Distance to human disturbance, Canopy cover, Soil traits, average distance to trees, average distance to shrubs, average distance to tree-falls, average distance to stumps) were recorded in each of 20 m×20 m plots. The data thus collected were analyzed using Cluster Analysis and Principal Component Analysis. The results showed that mud bath sites of the wild boar shared the following characteristics: absence of tree-falls and stumps, high levels of concealment, loess soil, canopy cover > 80%, average distance to trees moderate, average distance to shrubs less than 1 m, slope less than 30, broadleaf forest vegetation, distance to human disturbance greater than 500 m, and altitude greater than 1000 m. There were no obvious preferences concerning location and distance to water source.
