Abstract
With spatially intuitional landscape model (LANDIS), this paper simulated the long term (300 years) dynamic changes of forest landscape pattern in Huzhong Forestry Bureau in Daxing'anling Mountains under no cutting, clear cutting, gradual cutting, and selective cutting. Compared with no cutting, the other three harvesting modes decreased the distribution area of Larix gmelini and Picea koraiensis, but increased that of Pinus sylvestris var. mongolica and Betula platyphylla. Selective cutting had the smallest effect on the distribution area of Larix gmelini and B. platyphylla. Cutting changed the age structure of tree species and reduced the distribution area of over-matured forests. Compared with clear cutting, gradual cutting and selective cutting had more effects on this reduction. Under different forest harvesting modes, the aggregation of B. platyphylla and P. sylvestris var. mongolica had little difference, but great difference was observed on the agregation of L. gmelini and P. koraiensis.
