摘　　要：以距长和距的色泽及弯曲状况为依据对山西省5个地区狩猎季节雄性雉鸡年龄的划分表明,当年幼鸡、1龄和2龄以上鸡各占40.7％—46.0％、42.9％—49.0％和9.6％—12.1％。各调查区域雌雄鸡的体重范围分别是0.73—0.81kg和0.99—1.10kg。11月中旬以后,体重没有明显的季节变化。雄性幼鸡的重量低于1龄鸡,而1龄鸡的重量在有些地区低于2龄以上个体,但差异不显著(P>0.05),在有些地区则显著高于2龄以上个体(P<0.01)。The Ring-necked Pheasants (Phasianus colchicus) were shot in fall and winter of 1990—1991 in five areas of Shanxi province, China. On the basis of the length, color and shape of thesput, We divided the pheasants into juvenile, adult Ⅰ and adult Ⅱ ageclasses, which respectively ac- counted for 40.7%—46.0%, 42.9%—49.0% and 9.6%—12.1% of the fall-winter populations. Ean body weights in five areas varied from 0.73 to 0.81 kg in female and from 0.99 to 1.10kg in male. After the second the days of November, the pheasants' mean body weight had no singnificant seasonol variation either geographical varition. Juveniles were lighter than adult Ⅰ; adult Ⅰ were lighter than Ⅱ (but p>0.05) in some areas and heavier than adult Ⅱ (p<0.01) in the other areas.
