摘要
本文分别应用小样地法、平均木标准差对比法、综合评分法、优势木对比法对４株预选树（ｎｍ－２０、ｎｍ－１９、ｎｍ－１８、ｎｍ－０６）进行分析，制定选优标准，确定ｎｍ－２０为优树。分析结果表明：应用小样地法进行楠木人工林选优最客观、正确，工作量较少。若预选树生长量指标ｍｄ＞４０％、ｍｈ＞３０％、ｍｖ＞１４０％且形质指标符合，则可确定为优树。
The analytical results reveal that applying the small sample plot method to conduct the plus tree selection of Phoebe bournei Plantations is most objective and correct and its work amount is smaller.The candidate plus trees whose growth index md is >40%,mh>30% & mv >140% and whose form & quality indexes meet the criterions may be determined as plus trees.
