摘　　要：文章对吉林省重点国有林区人工林资源进行调查研究.结果表明:吉林省重点国有林区人工林面积3.457×10^(9)m^(2),人工林蓄积4660.26万m^(3),每公顷蓄积135.83 m^(3),林种以用材林为主,中龄林所占的面积和蓄积比重较大,人工纯林面积大于混交林.故建议吉林省重点国有林区人工林建设的方向为增加公益林,抚育幼龄林和营造混交林,不仅可以增加人工林的物种多样性,还可以保证人工林内生态平衡.In this paper,the artificial forest resources in the key state-owned forest areas of Jilin Province were investigated,The results showed that the area of planted forest was 345700 hm^(2),the volume of planted forest was 46602602600 m^(3),and the volume was 135.83 m^(3) per hectare,the area and volume proportion of middle-aged forest were larger,and the area of pure forest was larger than that of mixed forest.Therefore,it was suggested that the direction of plantation construction in key state-owned forest areas of Jilin Province should be increasing public welfare forest,tending young forest and constructing of mixed forest can not only increase the species diversity of plantation,but also ensure the ecological balance in the plantation.
