Abstract: Investigations were carried out frorn February 1989 to April 1990 in Taiyue mountain of Shanxi province.The adult's corpulence degree of common frogsis higher during hibernation aidlowest in May and June,and that of males is signlficantly higher than females'(except in August). During April-August,the coef-ficients of liver and fat are low,but begin to rise rapidly after August ai1d peak before hibernation. The co-efficient of gonad has a variation tendency roughly as same as that of liver and fat,but still riseb during hi-bernation and reaches maximum befOre reproduction. There are rernarkable differences for all indices be-fore and after hibernation. During hibernation,the decline rates of all indices for females are higher than those for males(except for gonad).
