为了说明在混交林中各森林分子的组合特点,衡量每个森林分子和其平均标准木的关系,就必须有一个具体的最有代表性的测树因子来反映林分生物学的特点。在林业经营的实践中,反映林分和立地条件的重要因子是树高。按林分平均高和年龄来确定地位级。据收集的很多材料证明,这一分类因子有很大缺
In order to illustrate the characteristics of forest assemblages in mixed forests and to measure the relationship between each forest species and its average standard wood, a specific and representative tree-measuring factor is needed to reflect the characteristics of forest biology. In the practice of forestry management, an important factor that reflects the conditions of stands and sites is the height of trees. According to the forest average height and age to determine the status level. According to the many materials collected, there is a great shortage of this classification factor
