摘　　要：通过对湖北省大悟县仙居顶林场喜树(Camptotheca acuminata Decne.)和杉木人工混交林中喜树生长量的调查,选取标准地标准木进行树干解析,分析喜树胸径、树高、材积的生长量,研究其生长规律。结果表明,该地喜树在前10年呈快速生长趋势,15年后稳定缓慢生长。By the investigation on the growth of Camptotheea acuminata Decne. from C. acuminata Decne. and cedarwood mixed forest locating in Xianjuding forest farm in Dawu county, Hubei province,the mean trees in sample plot were selected to conduct the stem analysis,and the growth of DBH, height as well as volume of C. acuminata Decne. were analyzedto study its growth rhythm. The results showed that, the investigated C. acuminata Decne. grew fast in the first ten years,and fifteen years later grew stably and slowly.
