Abstract

An investigation was made on the coarse woody debris (CWD) in burned forestlands in Huzhong area of Great Xing’ an Mountains. The loading capacity of CWD in the burned forestlands was 24.9-181.0 m3 x hm(-2), among which, snag and log occupied 24.3%-85.9% and 14.0%-75.7%, being 6.0-93.9 m3 x hm(-2) and 15.3-138.4 m3 x hm(-2), respectively. Significant differences were observed among burned forestlands and among years. The predominant DBH class of snag and log was 2.5-20 cm and 1.5-15 m, and the height of most snags and logs was 2.5-15 m and 5-20 cm, respectively. The loading capacity of CWD had no obvious change with the recovery of forest vegetation. The characteristics of CWD had a close relationship with pre-fire forest stand conditions and burn intensity.
