摘要

In Yingzuijie National Nature Reserve,Pinus massoniana forest,mixed broadleaf-coniferous forest and evergreen broad-leaf forest were investigated to study the changing characteristics of woody debris( WD) during various succession stages of evergreen broad-leaf forest. The results showed that during various succession stages of evergreen broad-leaf forest in Yingzuijie National Nature Reserve,WD storage of each forest ranged from 1. 26 to 8. 82 t /hm2,with the order of P. massoniana forest <mixed broadleaf-coniferous forest < evergreen broad-leaf forest,that is,it increased from early to late stages of the succession. At different succession stages,coarse woody debris( CWD) storage was 2-9 times more than fine woody debris( FWD) storage,revealing that CWD was dominant in WD of each forest. CWD biomass accounted for 0. 66%-2. 21% of arbor biomass,so the forests were at the developmental stage.
