赣南不同坡向杉阔混交林物种多样性初步研究

Study on the Species Diversity of Cunninghamia lanceolata and Broadleaved Mixed Forest with Different Slope Aspects in South Jiangxi

在江西大余县帽子峰林场,通过标准样地法对不同坡向杉阔混交林的物种多样性进行调查研究,结果表明:杉阔混交林不同坡向的植物种类和物种多样性有明显差异,阳坡植物种类较阴坡丰富,阳坡有利于保持乔木层及草本层的物种多样性,阴坡有利于保持灌木层的物种多样性,且物种分布较均匀。

The species diversity of Cunninghamia lanceolata and broadleaved mixed-forest of different slope aspects were studied through standard sample plot method in Jiangxi Dayu Maozifeng Forest Farm. The results showed that the plant species and species diversities were different with different slope aspects, the sunny slope had more plant species than shady slope, and it was beneficial to keep species diversity of arbor layer and herb layer, but the shady slope was advantage to keep species diversity of shrub layer and had more homogeneous species distribution.
