摘要：The study of the natural regeneration of an artificial Platycladus orientalis stand is important in orderto reflect the potential trend of the stand. This field investigation was carried out in the Shisanlingforest farm in Beijing. We analysed the factors that influenced the natural regeneration using the graycorrelation method. The results showed that the regeneration status was bad in height classes of 0-30 cm and 30-50 cm, while it was moderate in the height class of >50 cm; the overall regenerationstatus was moderate. Eight factors that affected the natural regeneration, in a descending order, are:altitude, aspect, soil depth, slope position, stand density, gradient, shrub-herb cover and litter thickness.It was difficult to satisfy the demand of stand self-replacement because the natural regeneration ofartificial P. orientalis stands was poor.
