摘　　要：为探索人工因素对东北林蛙(Rana chensinensis)生长发育的影响,采用骨龄学方法比较了野生和半人工养殖林蛙发育的差异性。结果表明:不同性别半人工养殖林蛙的体长、体质量均值都极显著大于野生林蛙的(p<0.05);半人工养殖林蛙的趾骨直径大于野生林蛙的,但差异不显著(p>0.1)。由von Bertalanffy’s方程得出:半人工养殖雌性林蛙的k值(k=0.401)大于野生雌性林蛙的(k=0.38),半人工养殖雄性林蛙的k值(k=0.558)大于野生雄性林蛙的(k=0.515)。由林蛙趾骨直径相对增长率的计算可知,相同年龄组内,半人工养殖林蛙的相对生长速率均大于野生林蛙。The experiment was conducted to study the effects of artificial factors on the growth of Dybowski＇s frogs and compare developmental differences between wild and semi-free farmed frogs by skeletochronology. The body length and weight of semi-free farmed frogs are significantly higher than those of wild frogs（ p 0. 05）. The phalanx diameter of semi-free farmed frogs is longer than that of wild frogs,but the difference is not significant（ p0. 1）. By von Bertalanffy equation, k（ 0. 401） for semi-free farmed female frogs is higher than that for wild female frogs（ 0. 38）,and k（ 0. 558） for semi-free farmed male frogs is higher than that for wild male frogs（ 0. 515）. The relative growth constant of semi-free farmed frogs is higher than that of wild frogs in the same age group.
