吉林省长白山区野猪种群资源现状调查

Population Status of Wild Boar(Sus scrofa ussuricus) in the Changbaishan Mountains,Jilin Province,China

于2007年至2009年的两个冬季,采用样带法对长白山区的野猪资源现状进行了调查。根据野猪的生物学特性以及长白山地区的自然环境特征,随机布设样带189条。对样带内野猪活动新鲜足迹链进行记录,并对其它痕迹进行综合分析,转化成实体数,计算样带密度,运用DPS7.05软件进行统计分析,求出吉林省东部长白山区野猪的种群数量,结果表明,野猪在长白山区种群数量2007年为31514.81±3912.18头、2008年为33725.22±4243.57头,其种群发展呈上升趋势。

The population status of wild boar was studied using line transect method in Changbaishan Mountains,Jilin Province,in the winters of 2007/8 and 2008/9.According to the wild boar＇s biological characteristics as well as the natural environments of the Changbaishan Mountains,189 transect lines were set randomly.Combining experience,fresh tracks and other active traces which were recorded and analyzed in general inside the transect lines were translated into entities.We calculated the definite transect line density.Then carried on the statistical analysis with the DPS7.05 and calculated the wild boar population quantity of the Changbaishan Mountains.The result showed that there was a population of 31514.81±3912.18 in 2007 and 33725.22±4243.57 in 2008 approximately in Changbaishan Mountains.The population rendered an upward trend.
