摘要
利用灰色关联分析方法,对灵空山辽东栎萌芽更新与海拔、坡向、坡度、坡位、灌木层盖度、草本层盖度以及枯落物层厚度等七项立地因子之间的关系进行了分析。结果表明,坡向、坡度、坡位为影响辽东栎萌芽更新的主要立地因子;辽东栎萌芽最适宜生长的立地条件为海拔1 850 m、阳坡、坡度35°、下坡。
Using Gray incidence analysis, the relationship between sprout regeneration of Quercus liaotungensis in Ling Kong Shan and elevation, slope direction, slope, slope location, bush coverage, grass coverage and deciduous leaves was analysed. The result showed that slope direction, slope degree, slope location were main factors affecting sprout regeneration of Quercus liaotungensis,and the suitable stand condition for Quercus liaotungensis required an elevation of 1850m, sun-faced slope and a slope of 35 degrees.
