摘　　要：选择了不同坡形、坡位以及不同混交比例的厚朴混交林和厚朴纯林,研究了立地因子对厚朴生长的影响,结果表明,不同立地因子对厚朴和杉木的胸径、树高均产生了极显著影响,相同坡形的下坡位生长量优于上坡位;相同混交比例上,凹形坡生长量均优于凸形坡。实际造林中,应根据培育目标合理选择立地类型和混交比例。The effects of site factors on growh of Magnolia officinalis were studied by choosing mixed forest and pure forest of Magnolia officinalis with different mixed species proportion at different slope shape and slope position.Result shows that different site factors have significant effects on DBH and tree height of Magnolia officinalis and Cunninghmia lanceolata.The growh of downhill with the same slope shape is optimal than that on uphill;the growh of the concave slope is optimal than that of the convex slope.In actual afforestation,the site type and the mixed species proportion should be selected according to cultivate goals.
