| 摘 要： | 1985一1987年间，作者在中国东北大、小兴安岭林区，根据三阶抽样的原理，选择1 6块样地，设置并调查202条样带，长2476．6km，遇见309条驼鹿足迹链。由此，明确了驼鹿在中国的分布区域并确定总栖息面积为1 9万多km2 ．平均分布密度为0.0519头／km2，种群数量为9955士397头(a=0．2 ），其种群下降率年平均逃6.3 %,且呈继续下降趋势, 亟待保护。

| Abstract: | Using the 3 orders sampling method，the authors selected 16 sampling sites andreplaced 202 sampling lines which were 2 476．6km in length，and 309 trail lines of moose(Alces alces)were counted in Da and Xiao Xinganling Mountains of Northeastern China,during the winter of 1985-1987．From these data，the geographical distribution and population size were determined as follows:the total area of moose habitat is about 1 90000km2 ，the average density is 0．0519 individuals／km2 and the population size is 9 955+397 individuals． In the meantime，annual descending rate was 6．3 %． Now the moose population in China is greatly need to protect．Lastly,the reasons of causing the moose population to reduce，as well advantage and shortcoming of the investigation method were discussed. |
