摘　　要：对北江中上游的乐昌林场生态公益林筛选的29种树种的早期生长进行了比较分析与研究。结果表明:米老排、木荷、山乌桕、毛桃木莲、喜树、陀螺果、山桐子、虎皮楠、樟树和火力楠适宜选作当地的生态公益林树种;竹柏、黄果厚壳桂、交让木、珊瑚树不宜选作当地的生态公益林树种;其他树种能否选作当地的生态公益林树种,有待后期观察。The early growth of 29 tree species selected for the ecological publie-weffare forest was studied at Leehang Forest Farm in Beijiang uppuer reaches. The results showed that 10 species of Mytilaria laosensis, Schima superba, Sapium discolor, Manglietia moto, Camptotheca acuminata, Melliodendron xylocarpum, Idesia polycarpa, Daphniphyllum oldhami, Cinnamomum camphora and Michelia macclurei were suitable for the ecological public-welfare forest, while four species including Nageia nagi, Cryptocarya concinna, Daphniphyllum macropodum and Viburnum odoratissimum were not. Further more observations and studies were needed to estimate if the other 15 tree species could be used for the ecological public-welfare forest in this areas.
