| 摘 要： | [目的]便于进行林分平均木、优势木数据转换，获取林分优势木信息。[方法]通过在塞罕坝机械林场获取的5个林龄。共178块临时样地的数据，对华北落叶松平均木和优势木树高相关关系进行研究。[结果]建立起平均木一优势木树高模型：DomH=2．162＋0．98AvgH。通过模型可知，华木落叶松林林分优势木高要比林分平均木高高出近2m。[结论]该模型便于在只取得了林分平均木高的情况下，换算得到林分优势木高。

| Abstract: | [ Objective ] It was convenient for data transformation between average height and dominant height. [ Method J In this paper, the da- ta of 178 temporary stand totally at five forest age level was used to study the correlation between average height and dominant height of Lar/x principls-rupprechii. [ Result] The paper established the average height and dominant height model ： DomH = 2. 162 ＋ 0.98AvgH. Based on the model, Dominant height of Larix principls-rupprechii was nearly two meters higher than average height. [ Conclusion] The model was conven- ient for getting the dominant height under the conditions of having average height only. |
