Characteristics of coarse woody debris |in Huzhong area of Great Xing’an Mountains.

Abstract

Abstract: An investigation was made on the coarse woody debris (CWD) in burned f
orestlands in Huzhong area of Great Xing’an Mountains. The loading capacity of
CWD in the burned forestlands was 249〖KG-*2〗-〖KG-*7〗1810 m3·hm-2
, among which, snag and log occupied 243％〖KG-*2〗-〖KG-*7〗859％ and 14.
0％〖KG-*2〗-〖KG-*7〗757％, being 60〖KG-*2〗-〖KG-*7〗939 m3·hm-2
 and 153〖KG-*2〗-〖KG-*7〗1384 m3·hm-2, respectively. Significan
t differences were observed among burned forestlands and among years. The predom
inant DBH class of snag and log was 25〖KG-*2〗-〖KG-*7〗20 c
m and 15〖KG-*2〗-〖KG-*7〗15 m, and the height of most snags and logs was
25〖KG-*2〗-〖KG-*7〗15 m and 5〖KG-*2〗-〖KG-*7〗20 cm, respectively. The loa
ding capacity of CWD had no obvious change with the recovery of forest vegetatio
n. The characteristics of CWD had a close relationship with pre-fire forest sta
nd conditions and burn intensity.
