摘要
通过典型样地法对小兴安岭地区的3种红松混交林进行重要值和生物多样性调查,探究重要值、生物多样性和更新之间可能存在的关系.研究发现,生物多样性与林分更新并无多大关系,但乔木树种的重要值却对森林的更新演替有着深远的影响.通过改变林分树种组成,在尽可能少的人为干扰条件下可达到改善森林更新的目的.
Using typical sample plot method,through investigating the importance value and bio-diversity of three kinds of Korean Pine mixed forest in the region of Xiaoxinganling,this article intended to find the possible relationship of the importance value,bio-diversity and forest regeneration.The result shows that the relationship is not obvious between bio-diversity and the stand regeneration,but the importance value of arbor has a far-reaching impact on forest regeneration and succession.By changing the stand composition of forests,foresters can improve the regeneration in the case of minimum interference.
