The growth of eight tree species that were used stand improvement at two plots under a Pinus caribaea stand was studied.Studied broadleaved tree species consisted ofCastanopsis fissa, Camellia oleifera, Acacia auriculiformis and Artocarpus nitidusat plot 1, and those consisted of Schima argentea, Symplocos lancifolia, Carallia brachiata and C.oleiferaat plot 1.Thegrowth of tree height decreased in the order ofC.fissa>A.auriculiformis>Artocarpus nitidus>C.oleifera, that of diameter at breast heightdecreased in the order of C.fissa>C.oleifera>A.nitidus>A.auriculiformis and that of crown widthdecreased in the order ofC.fissa>A.nitidus>C.oleifera>A.auriculiformisat plot 1;Tree growth was the greatest in C.fissaamong the four tree species.Thegrowth of tree height decreased in the order ofS.argentea>S.lancifolia>C.brachiata>C.oleifera,that of diameter at breast heightdecreased in the order ofC.oleifera>S.lancifolia>S.argentea>C.brachiata, and that of crown widthdecreased in the order ofC.oleifera>S.lancifolia>S.argentea>C.brachiataat plot 2.Growth of tree height was the greatest inS.argentea, whereas those ofdiameter at breast height and crown width was the greatest in C.oleiferaamong the four tree species.Overall, C.fissa, A.auriculiformis, S.argentea and C.oleifera were good tree species for stand improvementof P.caribaea stands.%对用于两块加勒比松林改造样地的8种阔叶树种(样地1:藜蒴Castanopsis fissa、油茶Camellia oleifera、大叶相思Acacia auriculiformis、红桂木Artocarpus nitidus;样地2:荷木Schima argentea、光叶山矾Symplocos lancifolia、竹节树Carallia brachiata、油茶)的生长进行了试验研究.结果表明:样地1的树高排序为藜蒴>大叶相思>红桂木>油茶,胸径排序为藜蒴 >油茶 >红桂木 >大叶相思,冠幅排序为藜蒴 >红桂木 >油茶 > 大叶相思,黎蒴的生长状况最好,树高、胸径及冠幅均最大.样地2的树高排序为荷木>光叶山矾>竹节树>油茶,胸径排序为油茶>光叶山矾>荷木>竹节树,冠幅排序为油茶>光叶山矾>荷木>竹节树,荷木长的最高,但油茶的在胸径和冠幅上生长更好.总体来看,藜蒴、大叶相思、荷木和油茶是加勒比松林改造的优良树种.
