Figure 1: Illustration of the two main landscape models. There are: process-explicit models, using specific processes (a), and neutral landscape models, using random functions (b). Process-explicit models often simulate landscape structure dynamics in terms of land cover (top-right), as well as bio-ecological and socio-economical processes (top-left) hosted by these structures. In addition, these processes are interacting (dashed arrows) through neighbouring fluxes that likely modify their dynamics (dashed curves). Neutral landscape models often simulate fixed landscape structures in raster mode (bottom-left), here adapted from Saura and Martínez-Millán (2000). To study agricultural landscapes some patchy neutral models (bottom-right), associated to linear networks (in black), have recently been built on the basis of Voronoï diagrams. Colours are representing hypothetical land covers.
