厦门市坂头国有林场2007年在采伐迹地上营造香樟、小叶榕、木荷建设生态风景林，经过7年的生长观察，结果表明：香樟和小叶榕年平均生长量分别为：树高0．69m、0．59m，胸径0．86cm、0．75cm，蓄积总生长量49．03 m3/hm2、36．05 m3/hm2，年均生长量7．0 m3/hm2、5．15 m3/hm2，树冠体积52．47 m3、49．5 m3，林木生长旺盛，能迅速形成景观效果，是生态风景林建设的良好树种。木荷由于种植在立地条件相对较差的位置，其生长也较快，可作为生态风景林建设的树种，除作防护林带经营外，也可作为用材林。%Since 2007 , the Cinnamomumhupehanum, Ficusmicrocarpa and Schimasuperbawere planted in the cutting blank for construction of eco -landscape forest by Bantou State -owned Forest Farm of Xiamen Municipality .Through seven years observation , the result showed that the annual average growth amounts of Cinnamomumhupehanum and Fi-cusmicrocarpa such as tree height , trunk diameter , accumulation of total growth , average annual growth and crown vol-ume are 0.69m, 0.86cm, 49.03m3/hm2 , 7.0m3/hm2 , 52.47m3 and 0.59m, 0.75cm, 36.05m3/hm2 , 5.15m3/hm2 , 49.5m3, respectively.Thriving trees may form the landscape effect fast , that are the suitable tree species for the development of eco -landscape forest .Although the Schimasuperba trees were planted in the location of poor land oc-cupation conditions , they still grew fast .This tree variety may also be planted for the development of eco -landscape forest that can not only be used as shelter belt but also the timber stand .
