title: [Long-term effects of different planting proportion on forest landscape in Great Hing' anling Mountains after the catastrophic fire in 1987].
abstract: With LANDIS model, this paper simulated the long-term dynamics of 100% larch (P1) 70% larch and 30% Mongolian Scotch pine (P2), 50% larch and 50% Mongolian Scotch pine (P3), 30% larch and 70% Mongolian Scotch pine (P4), and 100% Mongolian Scotch pine (P5) in the Tuqiang Forest Bureau at the northern slope of Great Hing' anling Mountains after the catastrophic fire in 1987, taking the forest under natural regeneration as the reference. The results showed that at the early, medium, and late stages of succession, different planting proportion all had significant effects on the abundance of larch, Mongolian Scotch pine, and white birch. The abundance of larch increased with time,while that of Mongolian Scotch pine was in a converse way. Larch and Mongolian Scotch pine had an increased abundance with their increasing planting proportion, but the abundance of white birch was higher under natural regeneration than under different proportions of planting. The abundance of white birch was positively affected by the planting proportions of larch and Mongolian Scotch pine. As for the total abundance of larch and Mongolian Scotch pine, it had no significant difference under P2, P3 and P4, but was higher than that under P1 and P5, indicating that individual-species planting should not be used in the forest landscape.
