| 摘 要： | 地种群年龄的研究表明，虽经人为频繁干扰，管涔肝扦天然林仍表现出异龄林结构特征，立木年龄范围超过一个级期，根据年龄结构特征值可分为相对龄林、相对异龄林和异龄林３种类型林下新一代种群的数量和结构受林冠郁闭度和结构的影响。具垂直郁闭型林冠的异龄林，林下更新数量充足，幼苗幼树年龄结构合理；而服闭型林冠，不利于一代种群的发生和发展，青扦种群年龄结构受种群发生和自疏两个过程的控制，林下种群的发生以小规模林冠空

| Abstract: | Age structure of natural spruce forests in Guancen Mountains remained the characters of uneven aged stands after long time of human disturbance. Age ranges of trees within the stand were all over one single age class(20 years). According to characteristics of age structure, the forests were divided into three types, that is, relative even aged forest, relative uneven aged forest, and uneven aged forest. The regenerations under forest canopy were greatly affected by density and structure of canopy. The ... |
