Abstract
The stocks and characteristics of coarse woody debris (CWD) are expected to reflect forest stand features. However, despite their importance, there have been no reports of CWD stocks and characteristics in the Qinling Mountains. We measured the CWD stocks in different CWD types, decay classes and diameter classes of the five forest types in the Qinling Mountains. The highest biomass of CWD was the Pinus tabulaeformis forest (12.57 t·hm-2), occupied 5.66% in the biomass of this forest, the lowest occupied 1.03% in Betula albo-sinensis forest (1.82 t·hm-2). Our results revealed that there was a strong correlation between CWD and forest biomass. When the CWD biomass were 9.9 t·hm-2 and 11.6 t·hm-2, the biomass of Pinus armandi forest and P. tabulaeformis forest reached maximum, respectively.
