小兴安岭红松种群天然更新及影响因子的探讨

The Natural Regeneration and Its Impact Factors of Korean Pine Population in Xiaoxing'anling Mountain

红松种群的天然更新一直是植被生态学家关注的重要问题,为了深刻了解红松天然更新过程,从红松土壤种子库、幼苗库、种群结构和动态以及群落结构和多样性等方面,对其天然更新状况及影响因子进行了综述和探讨,认为:红松的种子库和幼苗库可能由于松果采摘,其储藏量在减少;红松种群天然更新主要受鸟兽、林分郁闭度、林窗、森林采伐等生态因子的影响。建议采取控制松果采摘,保护野生动物,适度采伐或择伐,栽针保阔等措施来保护和维持红松林群落的发展和稳定更新。

The natural regeneration of Korean pine species has always been an important issue concerned by vegetation ecologists.To study further on the natural regeneration process of Korean pine,its natural update status and influencing factors are summarized and discussed from the Korean pine seeds,seedlings bank,population structure and dynamic and community structure and diversity.Now,the reservation of Korean pine seed and seedling bank amount are falling due to nut picking,and the natural regeneration of Korean pine population is mainly influenced by ecological factors,such as birds and animals,forest canopy density,forest gap and deforestation.To protect and maintain the development and stable update of Korean pine community,the measures of controlling to pick pine nuts,protecting wildlife,moderately cutting or selective cutting,planting conifers and protecting broad-leaved trees,and so on are recommended.
