- 摘要:
- 为使蒙古栎次生林生态系统达到近自然的状态，探讨经营方式对蒙古栎次林种群的影响，对不同经营方式下的蒙古栎次生林主要建群种的结构特征进行了比较研究。结果表明：除蒙古栎和胡枝子外，针阔混交林主要建群种生长情况均好于纯林；针阔混交林下蒙古栎实生幼苗的地径要大于纯林，即混交林下天然更新幼苗生长更好，对资源的利用也更充分；其余结构特征从数据分析上看没有十分明显的规律。
- Abstract:
- In order to make the Mongolian oak forest ecosystem be neatly natural state,and explore the effect of operation mode,the structural characteristics of mongolian oak populations in the same age and situation in different management were studied.The results showed that the populations growth situation of needle broad-leaved mixed Mongolian oak forest was better than pure forest,except Mongolian oak and lespedeza.The ground diameter for Mongolian oak seedlings of needle broad-leaved mixed forest were better than pure forest and it could use resources more fully.There was no obvious disciplinarian of other structural characteristics.
