摘　　要：观察了人工饲养条件下成年雄性白豚“淇淇”性自慰行为的表达方式及其变化周期。性自慰行为有腹部贴池底、贴池壁和阴茎外露三种主要表现形式。性自慰行为有季节性变化趋势。腹部贴池底行为全年都发生 ,贴池壁行为和阴茎外露行为有明显的春季、秋季两个高峰 ,且春季高于秋季。性自慰行为发生的周期性变化是豚性腺活动的表现形式。性自慰性行为发生的先后顺序为贴池底、贴池壁和伸出阴茎。The patterns and cycles of sexual masturbation behavior of one captive male baiji, 'Qi Qi', were reported in this paper. The patters of the behavior consisted of ventral contacting with pond bottom, ventral contacting with pond wall and spreading out of penis. The variation of sexual masturbation behavior seemed to follow a seasonal pattern. The ventral contacting with pond bottom occurred monthly all the years. The ventral contacting with pond wall and spreading out of penis did not occur monthly, but apparently had two peaks one year and the peak in spring was higher than one in autumn. These cycles of sexual masturbation behavior were considered to be indicatives of sexual activity. The occurring sequence of sexual masturbation behaviors was the ventral contacting with pond bottom, ventral contracting with pond wall and spreading out of penis in a period of year.
