黑龙江省东北虎野外种群监测研究

The Wild Population Monitor of Amur Tiger in Heilongjiang Province

2003～2004年,在黑龙江省建立了东北虎监测网络系统,共记录到东北虎活动足迹链等信息25个.监测结果表明,黑龙江省东北虎目前分布于完达山东部、老爷岭南部和张广才岭南部3个独立的分布区,东北虎的数量在9～11只之间,其中完达山东部5～6只(1～2♂,2♀,2幼体),老爷岭南部3～4只(1～2♂,1♀,1亚成体),张广才岭南部1只(1♂).在完达山东部乌苏里江流域的中俄边境地带存在东北虎迁移生态通道;老爷岭南部的中俄边境与吉林省交界地带有东北虎跨境迁移活动,并发现亚成体;完达山东部是黑龙江省东北虎最适宜的栖息地,并且存在东北虎的繁殖个体,是东北虎种群恢复和增长最具潜力的林区.

An Amur tiger （Panthera tigris altaica ） monitoring network system was set up for its population monitor during 2003- 2004, and 25 active tracks were spotted in the process. The results indicated that in Heilongjiang Province, the Amur tiger mainly distributes in the eastern areas of Wanda Mountains, the southern areas of Laoye ridges and Zhang guangcai ridges separately. The total population of Amur tiger is 9--llthat include 5-6 in eastern Wanda Mountains （1- 2 male, 2 female and 2 young）, 3-4 in the southern Laoye ridges （1-2 male, 1 female and lsub adult） and 1 in the southern Zhang Guangcai ridges （1 male ） separately. There is an ecology corridor for Amur tiger migration in Sino- Russia frontier area near Ussuri river of eastern Wanda Mountain area. Also Amur tiger can be found in areas of Sino - Russia frontier area of the southern area of Laoye ridges and Jilin Province. Sub adults were also observed in these areas. The eastern areas of Wanda Mountains in Heilongjiang Province were the most suitable habitat for Amur tiger and were also the most potential forest area for Amur tiger reproduction, population resume and enlarge.
