极端天气干扰下闽北人工林林隙形成方式及其特征

Gap Formation in Plantations in Northern Fujian Province Under Disturbance of Extreme Climate and Their Characteristics

  • 摘要: 对福建省顺昌县宝庄村人工林在极端天气干扰下形成的林隙进行调查,研究人工林林隙分布及其特征。结果表明,在宝庄村人工林中,树木倒伏形成的林隙最为常见,占林隙总数的32.98%;其次是树木翻兜形成的林隙,占27.66%。林隙形状不规则,林冠空隙(CG)和扩展林冠空隙(EG)面积主要集中在600~800m2;形成木数量组成以100~150株为主,形成木分布最多的径级在10~15cm,构成形成木的主要树种是马尾松、杉木、毛竹。以林隙形成特征为参照,对受灾人工林的恢复提出建议。

     

    Abstract: The forest gaps formed in plantations under disturbance of extreme climate in Baozhuang Village of Shunchang County, Fujian Province were surveyed to analyze the distribution and characteristics of the gaps formed in plantations. The results showed that in the plantations in Baozhuang Village, tree falling was the most common reason for gap formation, accounting for 32.98%, followed by uprooting, which accounted for 27.66%. The shape of the gaps was usually irregular, the size of canopy gaps (CG) and expanded gaps (EG) was mainly in the range of 600-800m2. Most of the gaps were formed by 100-150 trees 10-15cm large in DBH, and the major tree species for the gap formation were Phyllostachys pubescens, Pinus massoniana and Cunninghamia lanceolata. Some proposals were put forward for restoration of the disaster damaged plantations based on the formation characteristics of the gaps.
