摘要
红松(Pinus koraiensis Sieb.et Zuee.)是东北地区著名的木本粮油树种,其生产的松籽闻名于世。通过对黑龙江省森工林区红松资源的分布、起源、林龄结构、各种经营区面积的统计分析,认为天然林占18.61%,幼龄林占80.85%,表明用于生产松籽的面积较少;禁伐区与限伐区面积占82.04%,大部分应为公益林;现有红松林的中龄林内密度普遍偏大,个体间竞争激烈,分化严重;总体上经济效益普遍低下。对此,我们认为:应该加强天然林保护;合理改建禁伐区与限伐区,向红松果林方向发展,提高经济效益;开展红松果林培育,增加科技投入,提高经营水平。
Pinus koraiensis Sieb.et Zuee.is famous tree specie of woody cereal-and oil-yielding plant for it's well-known seed.By the survey of the existing forest resource of Pinus koraiensis Sieb.et Zuee,it Show us that natural stand goes up to 18.61%,young forest stand 80.85%,this reality reveals that stand aimed to seed-providing is less.Stands area of bidden for cutting is up to 82.4%,the most is public welfare forest.The density of the existing young forest stand is too high that competition and differentiation seriously between individuals.The whole economic benefit is less.So we think that the construction of forbidden area should be logical,the protection of natural forest should be enforced,the silviculture of Pinus koraiensis Sieb.et Zuee.should be developed and the investment should be increased so as to promote the management level.
