以闽东南地区3个立地条件不同的8年生马占相思人工林为研究对象,运用方差分析、多重比较等方法,分析出马占相思林分的生长状况及其影响因素。结果表明,坡向对马占相思存活率影响很大,林分密度和混交程度对林分的胸径、单株材积无显著影响,但对树高生长量有显著影响。3个样地中,坡向为南坡、林分密度最大、无混交的林分蓄积量最大。
以閩東南地區3箇立地條件不同的8年生馬佔相思人工林為研究對象,運用方差分析、多重比較等方法,分析齣馬佔相思林分的生長狀況及其影響因素。結果錶明,坡嚮對馬佔相思存活率影響很大,林分密度和混交程度對林分的胸徑、單株材積無顯著影響,但對樹高生長量有顯著影響。3箇樣地中,坡嚮為南坡、林分密度最大、無混交的林分蓄積量最大。

In order to analyze the state of growth status in Acacia mangium forest stand and its influencing factors, the eight years of A. mangium in three different conditions site in the southeast of Fujian province took, and use using the method of variance analysis and multiple comparison analysis. The results showed that the slope impacts the survival rates of A. mangium most. The stand density and the degree of mixed forest stand had no significant effect on the DBH of forests stand and individual volume, but have significant effects on tree height growth. Among the three sample plot, the stands which in south slope have the biggest stand density and have no-mixed holds the biggest amount of accumulation.
