摘　　要：通过分析沙松解析木找出沙松胸径早晚期相关关系,制定沙松优树标准,为建立沙松无性系种子园打好基础。Through correlation analysis between early wood and late wood at breast height diameter by analytic tree of Abies holophylla,a selective standard of superior tree to this species was set down. It would lay a foundation for the establishment of clonal seed orchard of Abies holophylla.
