| 摘 要： | 对榆林地区不同林龄樟子松群落的自疏规律、生活史对策、病虫害发生情况以及自然更新等进行研究.榆林地区的樟子松群落不是稳定群落,但其有很强的竞争力和适应能力,目前正处于适应当地立地条件和气候条件的过程中,在今后的营林中应该注意防止病虫害大面积爆发,人工促进天然更新.

| Abstract: | The self thinning law,life cycle strategy and occurrence of disease and pest injury as well as natural regeneration of different age of Pinus sylvestris var. mongolica community in Yulin area were investigated. The results showed that: Yulin area community was not a stable community,however,the competition ability here was very strong, which was in the process of adaptation to the local site conditions and climatic conditions. In the future,pest outbreaks should be prevented in forest management,and natural regeneration should be stimulated artificially. |
