摘　　要：对重阳木以通径分析方法分析其生长状况与环境条件的关系。结果表明:多行的重阳木与其生长状况呈较强的正相关关系,除直接作用外,根系半深埋,根系损害以及地面硬化等均可通过其对生长状况产生影响;根系正常与冠幅生长相关性较强,除直接作用外,多行,根系伤害以及地面硬化程度均可通过其对冠幅生长产生影响;单行的重阳木与树干生长关系密切,除直接作用外,根系深埋、根系伤害程度以及地面硬化程度均可通过其对树干生长产生影响;根系深埋推迟发芽时间,除直接作用外,单行以及地面硬化均可通过其对发芽时间产生影响。The relationships between growth status and environmental conditions of Bischofia polycarpa were analyzed by path analysis in Anhui agricultural university. The results showed： environmental con- dition that was multi-line was closely related with growth status, in addition to direct effect, half-buried root, root damage and hardened groundcould impact on the growth status through its; healthy root had a significant relevant with crown growth, in addition to direct effect, the multi-line, root damage, and hardened ground could also impact on the crown broadness through its; single-line was closely related with the growth of trunk, in addition to direct effect, deep-buried root system, root damage and hardened ground could also impact on the trunk growth through its;deep-buried root greater impact on the germi- nation time, in addition to direct effect, single-line and hardened ground could also impact on the germi- nation time through its.
