摘　　要：对江苏南京地区北草蜥头、体大小的两性异形进行了研究。结果表明,北草蜥成体体长无显著的两性差异,两性异形主要表现为:雄性个体有较大的头部(头长和头宽),而雌性个体有较大的腹长;雄性个体头部的增长速率明显大于雌性,而其腹长的增长速率明显小于雌性。The sexual dimorphism of head and body size of Takydromus septentrionalis from Jiangsu of Nanjing were studied. The results showed that the body length of adult T. septentrionalis had no significant difference between male and female. The sexual dimorphism mainly shown as the male had bigger head（ head length and head width） and the female had bigger abdomen length. The growth rate of head of male T. septentrionalis was faster than that of female, but the growth rate of their abdomen length was slower than that of female.
