摘要
１９９１－１９９４，用标记重捕法研究了哈尔滨近郊中国林蛙的野外生长和种群密度。结果表明：除体重、眼间宽和吻长外，中国林蛙的头长、前臂及手长、体长和后肢长其长度与相应的增长率呈很强的负相关。同时，用施纳贝尔法分析了中国林蛙的种群密度，平均密度为４８．９４只／ｈｍ￣２．
From 1991 to 1994,the growth under field condition and population density of Rana chensinensis were observed in the suburbs of Harbin by means of the mark-recapture method.The results are as follows:Except the weight,interorbital space and snout length,significant negative correlation was found between head length,length of lower arm and hand,bpdy length,leg length and theirgrowth rates.At the same time,the population density of Rana chensinensis was analysed with Schaable -method.The average density of Rana chensinensis is 48.94/hm￣2.
