摘　　要：该研究对不同坡向和坡位的南方红豆杉轻基质苗和大田育苗的造林效果进行了探讨,结果表明:南方红豆杉2个类型苗木山地造林时在树高、地径、成活率等方面都存在较大差异,且差异极显著。不同坡位之间也达到了显著水平,但是不同坡向的差异性不明显。用南方红豆杉轻基质苗造林,造林后的早期生长和成活率都优于常规的大田裸根苗。下坡位的生长量从阳坡—半阳坡—阴坡是递增的关系,上坡位的生长量从阳坡—半阳坡—阴坡是递减的关系。以上结论可为南方红豆杉造林生产实践提供重要的理论依据。The contrast effect of afforestation by light medium seedlings and field bare-root seedlings with different slope directions and positions of Taxus chinensis var. mairei was studied. The results showed that ： the two types of Taxus chinensis var. rrtairei seedlings mountain afforestation were quite different in terms of tree height, basal diameter, survival rate, and the difference was significant. At the same time, there was significant difference with the slope positions, while no significant with slope directions. So, the early growth and survival rate of the seedlings using light medium seedlings afforestation method were better than conventional field bare-root seedlings. The growth of upper slope was as the following ： sunny slope 〉 half-sunny slope 〉 shady slope, while lower slope presented opposite phenomena. The results can provide theoretical basis for afforestation practice of Taxus chinensis var. mairei.
