摘要
采用Ｆ检验和ｔ检验的方法，对西藏东南部金珠藏布流域野外收集的孟加拉虎足迹数据进行数理统计，统计结果得到虎的６个个体样本，结合在当地的大量访查工作，确证了该流域至少有５只虎的分布。另外嘎隆藏布流域发现１只虎的踪迹。金珠藏布流域虎的活动小区有一定重叠，说明它们可能存在一定的亲缘关系。对金珠藏布流域及邻近地区虎的活动情况也进行了调查，调查结果表明虎的分布和数量自７０年代以来呈减少趋势。
The quantity and distribution of tigers (Panthera tigris tigris ) in Jinzhu Tsangpo valley, southeastern Tibet were investigated in 1995. We gathered and measured 30 trails and 93 footprints of tigers in this valley. By statistical method of F test and t test and a large number of investigate, five tigers and their activity range in Jinzhu Tsangpo valley were confirmed. Moreover, we found trails of one tiger in Galong Tsangpo valley near Jinzhu Tsangpo. We also conducted some survey on the future trend of tigers in Jinzhu Tsangpo valley and adjecent areas. These survey results indicated that the quantity and distribution of tigers had been decreasing since the seventies in Jinzhu Tsangpo and adjecent areas.
