红松种群扩散林营建技术研究

Research of Construction Technology of the Forest of Korean pine Population Diffusion

通过向次生林引入红松种群扩散林,对目标林分形成持续的红松种源供给,建立红松种群及阔叶红松林生态系统恢复的高效、低碳有效途径和长效机制。次生林红松天然更新受林分平均胸径和林分密度的显著影响,松鼠搬运松塔的活动主要集中在半径120~160 m范围。实现红松种群700株/hm2的恢复目标,需要红松种群扩散林的密度是74株/hm2,红松种群扩散林的面积约为目标林分面积的18.5%。

By introducing the forest of Korean pine population diffusion into secondary forest,a continuous germplasm source supply of Korean pine was formed for the Target Tree Stand.To establish an efficient,low-carbon and long-term mechanism for the restoration of Korean pine population and broadleaved Korean pine forest ecosystem.The natural regeneration of Korean pine in secondary forest was significantly affected by forest stand average DBH and forest stand density.Squirrels carry pine towers within a radius of 120 m to 160 m.To achieve the recovery target of 700 plants/hm2 of Korean pine population.The density of the forest that requires the forest of the Korean pine population diffusion is 74 plants/hm2.The area of the forest of Korean pine population diffusion is about 18.5%of the target forest stand.
