Multi-granularity virtual forest information model with linkage capability and its application

Due to lack of information correlation between different-granularity forest ecological calculation models, construction of different-level virtual forest landscape usually adopts a single ecological calculation model. In order to achieve the information correlation and transition between the different-level virtual forest simulations, this paper puts forwards a multi-granularity virtual forest information model with linkage capability (MGVFM). In addition, this model is applied in the forest ecological landscape simulation. Based on the principle that the environment factors have inherent relations with the different-level forest ecological calculation models, our experiment shows that the model proposed in this paper can construct information correlation in two space-time transition ways: large-scale to small-scale and small-scale to large-scale.
