| 摘 要： | 对秦岭林区天然油松林年龄结构，直径结构分析研究表明，天然油松林按林层和林龄可划为单层异龄林和复层异龄林两类。单层异龄林的天然更新表现出明显的连续性和阶段性，而复层异龄油松林的年龄结构出现多世代波动现，直径结构的波动随林龄的增加，其偏度具有一定的方向性。

| Abstract: | The analysis of the age and diameter structures in natural Chinese pine forests, Qinling Mountains shows that Chinese pine forests can be classified into two types,single-storedly even-aged forest and multi-storedly even-aged forest. The natural regeneration of single-stored forest expresses apparent continuity and stage traits, whereas multi-stored forest fluctuates in age structure and its deviation vary in certain orientation followed by the increment of stand age class. |
