摘　　要：通过调查闽北地区杉木纯林下套种的闽粤栲,初步探索闽粤栲的造林效果。结果表明,套种10 a后的闽粤栲树高总生长量最高为9.47 m、胸径总生长量最大为9.86 cm。与10年生闽粤栲纯林对比,闽粤栲能够在杉木纯林正常生长。杉木纯林套种闽粤栲的凋落物生物量为20740 kg·hm^(-2),明显高于杉木纯林的凋落物生物量(5980 kg·hm^(-2)),说明闽粤栲的套种可增加杉木纯林的生物量。We investigated the Castanopsis fissa intercropping in the Cunninghamia lanceolata pure forest in northern Fujian to explore the afforestation effect of interplanting C.fissa.The results showed that the maximum height and diameter at breast height(DBH)recorded for 10-year C.fissa in terms of growth are 9.47 m and 9.86 cm,respectively.Compared with the controlled C.fissa pure forest,C.fissa can grow in the C.lanceolata pure forest.The litter biomass of the C.lanceolata pure forest interplanting C.fissa is 20740 kg·hm^(-2),which is significantly higher than that of the C.lanceolata pure forest(5980 kg·hm^(-2)).It shows that interplanting C.fissa can increase the biomass of pure C.lanceolata.
