摘　　要：比较了广东省博罗县梅花林场11种8年生乡土树种的生长状况,并应用样方法调查分析了林分的物种多样性。结果表明,白楸(Mallotus paniculatus)、红苞木(Rhodoleia championii)、红锥(Castanopsis hystrix)和火力楠(Michelia macclurei)生长较快;大头茶(Gordonia axillaris)、柳叶桢楠(Machilus salicina)和拐枣(Hovenia dulcis)生长较慢。与造林初期相比,改造后8年生的林分物种多样性和均匀度稍有下降。研究表明,白楸、红苞木、红锥和火力楠均适合作为惠州市生态公益林和风景林的树种。The growth status of 11 8-year-old native trees was compared in Meihua Forest Farm,Buoluo County,Guangdong Province,were studied.Plot method was used to investigate the species diversity of the forest lands.The results showed that the growth rates of Mallotus paniculatus,Rhodoleia championii,Castanopsis hystrix,and Michelia macclurei were higher while those of Gordonia axillaris,Machilus salicina,and Hovenia dulcis were lower.As compared to the early stage,the species diversity and evenness of the community declined slightly after 8 years long enrichment.The results showed that Mallotus paniculatus,Rhodoleia championii,Castanopsis hystrix,and Michelia macclurei were suitable for ecological and landscape forest growth in Huizhou City.Based on the study,some measures were suggested to enhance the potential growth and ecological function of the native trees.
