一、引言 红松是我国东北区域长白山、完达山、张广才岭及小兴安岭林区的一个天然优势树种。 自建国以来,对于红松占主导的优势林分,进行了多种形式的采伐与更新,以便找出既能生产大量木材支援国家建设,又能很快的把红松林更新起来,不断的扩大森林资源,使森林越采越多,越采越好,青山常在,永续作业。但在历经二十多年的过程中,在小兴安岭林区的带岭看来,凡是更新起来比较又快又好的是人工植苗更新,又慢又少的是天然更新;在迹地类型上,皆伐迹地的人工林又是非常优于择伐迹地更新后的天然 First, the introduction of Korean pine is the northeastern region of Changbai Mountain, Wandashan, Zhang Guangcai Ridge and small Xinganling a natural advantage of tree species. Since the foundation of our country, many kinds of logging and regeneration have been carried out for the predominant stands dominated by Korean pine, in order to find out that not only can a large amount of timber be produced to support the construction of the country, but also the Korean pine forest can be renewed and expanded continuously Forest resources, making the forest more and more, the more the better, Aoyama often, sustainable operation. However, after more than two decades of development, it seems that in the belt of the small Xingan Mountains, it is natural that all the plants are renewed more quickly and better, and the slow and the slow are renewed naturally. The curtailed plantations are also very new to natural habitats
