长白山自然保护区中国林蛙种群现状及增殖措施

Status of Population of Rana chensinensis in Changbai Mountain Natural Reserve and Measures for Population Propagation

分析了长白山自然保护区中国林蛙种群的现状,观察了在采用相应措施的情况下林蛙种群的增长情况.结果表明：长白山自然保护区林蛙种群结构保持幼蛙占多的格局,但种群统计数量较过去已明显减少,同时林蛙个体大小的总体水平也已不如过去.采用为林蛙创造适宜繁殖生境和补充种源、加强放养管理等措施,可有效地促进林蛙种群的增长进程.

The status of the population of Rana chensinensis in Changbai Mountain Natural Reserve was analyzed through investigation,and the situation of the population growing under the condition of adopting the relevant measures was observed.The results showed that the population structure kept the pattern which the larvae were in majority,but the population statistical number had decreased obviously compared with the past,meanwhile the total level of the body size of the individuals was inferior to the past.Adopting the measures of creating available breeding habitat for the species and supplying species sources and strengthening stocking management could promote the population growing progress effectively.
