The spatial pattern of coarse woody debris (CWD) reflects the death and disturbance patterns of forest communities, and to some extent, the death of forest trees. The adjacent grid method was used to investigate the CWD, in a 1 hm² fixed plot, of the original Abies georgei var. smithii forest in the Sejila Mountain and analyze the spatial distribution of CWD from three perspectives:CWD type, decay grade, and diameter grade. The results showed that the total density of CWD in the plot was 582 plantshm², among which the inverted wood, the main form of CWD, accounted for 55.33%. The distribution of CWD density at the decay level can be fitted by a polynomial (R²=0.9973), while the distribution at the diameter level can be fitted by an exponential decay model (R²=0.9746), which is greatly affected by its types, decay grades, and diameter classes. Over a 50 m area, the overall performance of CWD displays a cluster distribution at a small-scale and random distribution at medium and large scales. Among the three CWD classifications, only the large dead branches, the first-grade decay, and the diameter-level I CWD displayed a strong cluster distribution at a small-scale or mesoscale and the rest were basically distributed randomly, but only reached or approached the cluster distribution at individual scales. The overall correlation between different types of CWD was not significant, and only the dead standing trees and large dead branches reached a significant negative correlation over a 0-21 m scale. The spatial distribution pattern of CWD is an important structural feature of the primitive forest of Abies georgei var. smithii, which largely determines the natural regeneration pattern of understory plant communities and forest types.
