Context. Study of interplay of disturbance and forest succession is key to understand forest landscape dynamics, especially under changing climate and disturbance regimes. However, most such studies are from small spatial and temporal scales, and thus may be limited to generalize at large scales. Objectives. We investigate how typhoons affected forest dynamics at stand and landscape scales, whether the impacts differ among forest biomes, and whether a post-volcanic forest landscape could ultimately reach equilibrium under typhoon disturbances. Methods. We used landscape modelling to spatially reconstruct the time-series (1710–2010) for the postvolcanic- eruption forest landscapes driven by forest succession and typhoon in Changbai Mountain, China. We compared aboveground biomass (AGB), climax tree species importance value, degree of recovery, and landscape pattern between northern (with typhoons) and southern and western Changbai Mt. (without typhoons). Results. The effects of typhoon disturbances were minimal when forests were young (before ~1810) but gradually increased as tree grew and forest recovered. The response of forest biomes to typhoon varied, which can be attributed to individual species traits. With recurring typhoons landscape did not reach an equilibrium until 2010. However, the effects of typhoons on landscape pattern gradually stabilized after 1960, suggesting landscapes with typhoons may eventually reach a steady state. Conclusions. Typhoons have long-lasting and cumulative effects that varied with successional-stages and forest biomes. Landscape under infrequent, large disturbances is nonequilibrium in the short term, but may ultimately reach equilibrium over long time periods. Historical landscape reconstruction reveals fuller spectrum of interplays of typhoons and succession.
