ZELIG.CBA model consists four sub-models: growth model simulating annual increment of individual tree in forest, regeneration model simulating annual establishment of different tree species, mortality model simulating annual agerelated and stress-related morality; and silviculture model simulating the forest response to different silviculture scenario. The validation of the ZELIG.CBA showed that the accuracy of the model for the forest growth was more than 95%. The succession from clear cutting site simulating showed that the ZELIG.CBA model was stable for long term simulation. And selective cutting experiment showed that the optimal scenario for broad-leaved Korean pine forests was removal volume 30% combining with 30a rotation.展开更多

The species composition, number, origin,decayed class and sizes of gap makers were studied comprehensively. The comparative studies of regencration inside and outside of canopy gap showed that the density of regeneration inside canopy gaps was 30% higher than that outside canopy gaps. The specific species regeneration response to canopy gap varied greatly. Pinus koraiensis, Picea jezoensis Frarinlis nla)ldshurica, JItghI)ls )nalJholu-i`a and Acer mono generally did not response to canopy gap disturbance. The Regeneration Importantce Valuc (RIV) of Abies nephrolepis, Ulmus Japonica increased with canopy gap disturbance. RIV of Tilia amurensis, Acer madshurica and Ulmus laciniata decreased with canopy gap disturbance. Canopy gap disturbance was not strong enough to result in the regeneration of some rpecies of shade intolerance such as Larix olgensis, Betula platyphylla.展开更多
