林口林区的原始阔叶红松林是地带性顶极群落 ,具有丰富的物种多样性 ,生物量大。由于长期的过量采伐与严重破坏 ,形成了大面积低、中密度的杨、桦、柞、杂木天然次生林 ,趋向中性和耐荫的硬阔叶林阶段 ,并顽强的、缓慢地向阔叶红松林方向发展。目前仍处在原始阔叶红松林的弹性极限之内。在天然次生林下和林间空隙小生境 ,最适宜红松的更新与生长。当前次生林中缺少红松种源 ,只要在空白生态位上人工栽植红松壮苗 ,保留天然阔叶树 ,并适时适法进行抚育 ,为红松生长创造上方适光和侧方庇荫的环境条件 ,就能尽快恢复接近自然的阔叶红松林
The original broad-leaved Korean pine forest in Linkou forest area is a zonal climax community with rich species diversity and large biomass. Due to long-term over-harvesting and serious damage, a large area of low, medium-density natural secondary forest of poplar, birch, oak and zoology was formed, which tended towards neutral and shade-tolerant hardwood forest. Leaf red pine forest development. It is still within the elastic limits of the original broad-leaved Korean pine forest. In the natural secondary forest and forest niche niche, the most suitable for the regeneration and growth of Korean pine. The current secondary forest is lack of Pinus koraiensis provenance, as long as the artificial white pine seedlings in the niche, the retention of natural broad-leaved trees, and timely appropriate method of tending for the growth of Korean pine to create the top of the appropriate light and lateral shade of environmental conditions As soon as possible to restore close to the natural broad-leaved Korean pine forest
