Mass loss of Pinus massoniana and Cinnamomum camphora leaf litter in forest gaps of different size*

Forest gap plays an important role in optimizing and adjusting the structure of plantation. However, researchers are not clear whether the gap size affects mass loss, or which gap size contributes more to litter decomposition. This research set up a field litterbag experiment to study the effects of different forest gap size on mass loss of Pinus massoniana ( Pm ) and Cinnamomum camphora ( Cc ) leaf litter. The Pm plantation was thinned to establish seven different gap sizes (G1: 100 m 2 , G2: 225 m 2 , G3: 400 m 2 , G4: 625 m 2 , G5: 900 m 2 , G6: 1 225 m 2 , G7: 1 600 m 2 ); closed canopy was used as the control. The results showed 1) the forest gap size had significant effect on mass loss of Pm and Cc, with the k value of Olson decomposition model as G4 > G1 > CK > G2 > G3 > G5 > G6 > G7 in Pm , and G2 > G4 > G1 > CK > G5 > G6 > G7 > G3 in Cc.
