摘要
红海榄是重要的红树植物之一,其大量的支柱根在生态上具有重要的意义。通过红海榄支柱根在纵、横2个方面的分析,提示红海榄支柱的分布格局。对5种红海榄群落的研究表明,在垂直方向红海榄支柱根的分布高度为0—150cm,其中大部分集中在30—80cm。在水平方向上,红海榄支柱根主要分布在冠幅的20%~70%位置,即离树干基部54~190cm区域,呈双峰分布,拥有2个密集分布区。
Rhizophora stilosa whose abundant stilt root has an important meaning in ecology is one of the important mangroves. The distribution of stilt root was derived from the stilt root distribution on longitudinal direction and landscape orientation. The conclusion shows the stilt root in longitudinal direction locate in 0-150 cm from the tree and more of them locate in 3-80 cm. Landscape orientation of the stilt root mainly locate in 20%-70% crown site, that is, 54-190 cm from the base of the tree. There were two apexes with two dense distributing areas.
