【摘要】 在充分调查辽东地区辽东楤木生长环境的基础上,通过标准地和样带调查,研究影响辽东楤木生长的主要环境因子。经方差分析和多重比较得出:坡向、坡度、栽植密度、树龄和郁闭度对辽东楤木生长状况都有显著影响。同时,利用Auto CAD软件绘制辽东楤木的林缘分布图,距离林缘0~1 m、5~6 m内辽东楤木分布较多且较均匀;离林缘近的区域辽东楤木生长状况好于离林缘较远的区域。更多还原

【Abstract】 Based on the comprehensive investigation of Aralia elata growing environment in Eastern Liaoning, the growth conditions and the environmental factors of A. elata were studied in sample plots and belt transects. Main factors that affected the growth conditions of A. elata were studied by employing analysis of variance and multiple comparisons.The results showed: slope position, gradient, planting density, age of A. elata and canopy density had very significant influences on the growth of A. elata. At the same time, cartographic software auto CAD was used of to draw the distribution picture of A. elata near forest edge. A. elata distributed more homogeneous in the area 0~1 and 5~6 meter from forest edge. And A. elata grew better in the area which is nearer to forest edge than the farther.更多还原
