燕山北部山地不同生境水曲柳幼树生长的比较
|
摘要
为了解水曲柳幼树在燕山北部山地的生长状况,以及生境对水曲柳幼树生长的影响,对林间空地、高密度林冠下、低密度林冠下和裸地4种不同生境下水曲柳幼树生长特征进行调查研究。结果表明:林间空地生境中,水曲柳幼树的地径和树高最大,在高密度林冠下和裸地生境中较低;造林后第2年第、第3年树高生长量由高到低分别为林间空地>低密度林冠下>高密度林冠下>裸地;树高生长量呈逐年增加的趋势。由此得出结论,林间空地最适宜水曲柳幼树的生长,水曲柳在冀北山地生长状况良好,可在当地进行推广造林。
In order to understand the growth of Fraxinus mandshurica young trees in north region of Yan Mountain and the effects of habitats on the growth of Fraxinus mandshurica young trees, the growth characteristics of Fraxinus mandshurica young trees in four different habitats under gap,high-density canopy,low-density canopy and bare land were studied.The results showed that the ground diameter growth and tree height growth of Fraxinus mandshurica young trees were the highest in the gap habitats,and were lower under the high-density canopy and bare land habitats. In the past 2 years,the growth of tree height from high to low is the gap> low-density canopy> high-density canopy> bare land;the growth of tree height is increasing year by year. It is concluded that the gap habitat is most suitable for the growth of Fraxinus mandshurica young trees, and the Fraxinus mandshurica young trees is well grown in north mountain of Hebei, and can be promoted and afforested locally.
