Application of GIS in dynamic simulation of forested landscapes

Abstract

Abstract: Linking a forest dynamic model to a relevant Geographical Information System(GIS) through the transformations between data files in the model and database in GIS, the simulation of forested landscape dynamics can be carried out. It is proved that this modelling approach has mainly three advantages of flexible data input, time-save running and more capable run output including tables, figures and maps. The components and structure of GIS, the choice and running of forest dynamic models, and a case study using this method in Changbai Mountain of China are also introduced in this paper.

Key words: Forested landscape, Geographical Information System, Forest dynamics, Simulation model, soil enzyme activity, aggregate stable, mineral N fertilizer reduction and organic fertilizer substitution, N fertilizer, organic fertilizer, soil biological activity.
