Abstract: The spatially explicit landscape modeling is a now highlighted concern in the study of landscape ecology. Spatially explicit landscape models are designed to simulate ecological processes at landscape scale on heterogeneous landscapes. Their outputs include both non-spatial data and spatial data. Thus, spatially explicit landscape model validation not only includes non-spatial data validation but also spatial data validation, which is a great challenge for traditional validation method developed from the validation of non-spatial data. In this paper, we reviewed the development of spatially explicit Landscape models and the available methods for spatially explicit Land scape model validation. The key area of future study on spatially explicit landscape model validation was also identified.
