基　　金：国家林业局野生动植物保护司资助项目:黑龙江省野生东北虎野外种群监测

摘　　要：2005年1月至2006年12月利用划分监测区的方法对黑龙江省境内野生东北虎进行监测,通过测量前足迹掌垫宽度的方法对野生东北虎进行个体识别,确定了野生东北虎的分布区及其种群变化情况。结果表明,黑龙江省有野生东北虎12～14只。其中,完达山东部分布区种群数量为5～6只,由2只雄性个体,2只雌性个体和1～2只亚成体组成;老爷岭南部分布区种群数量为3～4只,由1～2只雄性个体,1只雌性个体和1只亚成体组成;老爷岭北部分布区种群数量为4只,由2只雄性个体和2只雌性个体组成;张广才岭南部分布区监测期间未发现东北虎活动信息。监测结果与近几年调查的结果相比,分布区域和种群数量都发生了变化。在4个分布区中,老爷岭北部分布区是再次出现东北虎活动的区域,张广才岭南部分布区未监测到东北虎的活动信息,可能没有分布。完达山东部分布区、老爷岭南部分布区和老爷岭北部分布区种群数量略有上升,张广才岭南部分布区呈现下降趋势。We inspected regional distributions and population sizes of wild Amur tiger （ Panthera tigris altaica ） by partitioning the monitor regions and identified individuals of wild Amur tiger through measuring front pad widths from 2005 to 2006. The results shown that there were 12 - 14 wild Amur tigers in Heilongjiang Province. The Eastern Wandashan population includes 5 -6 individuals （2 males, 2 females and 1 -2 subadults）. The Southern Laoyeling population comprised 3 -4 individuals （1 -2 males, lfemale and 1 subadalt）. The Northern Laoyeling population had 4 individuals （about 2 males and 2 females）. No individuals were monitored in Southern Zhangguangcailing. The distribution regions and population sizes of wild Amur tiger in 2005 -2006 （ 12 - 14） have changed comparing with those in the past few years. Among the four regions, wild Amur tigers distributed in Northern Laoyeling again. However, no activity was found in Southern Zhanguangcailing region, perhaps there have no population distribution. The population sizes increased slightly in Eastern Wandashan, Southern Laoyeling and Northern Laoyeling, but declined in Southern Zhangguangcailing.
