摘　　要：通过马尾松杜英混交林、马尾松闽粤栲混交林和马尾松纯林生长状况、林分植被生物多样性和土壤理化性质的研究,结果表明,马尾松与杜英、闽粤栲混交后,树高、胸径生长量增加明显,蓄积量增大;马尾松混交林下植被种类和数量都增多,生物多样性比马尾松纯林丰富;马尾松混交林土壤理化性质得到较大改善。Growth, biodiversity of stand , physical ＆ chemical properties of soil of mixed forest of Pinus massoniana ＆ Elaeocarpus sylvestris, mixed forest of Pinus massoniana ＆ Castanopsisfissa, pure forest of Pinus massoniana were studied. Result shows that growth increment of tree height, DBH ＆ volume increase significantly after mixing of Pinus massoniana, Elaeocarpus sylvestris ＆ Castanopsis fissar;species and numbers of plant of mixed forest of Pinus massoniana all increase; biodiversity is richer than that of pure forest of Pinus rnassoniana; soil physica/ ＆ chemical properties of pure forest of Pinus massoniana improve significantly.
