Land suitability evaluation is the basis and core of overall land use planning. With global population increasing and environmental problems deteriorating, it is important and urgent to implement the research on land suitability for dealing with the relation between population and resources and with sustainable development. Based on indexing an amount of references, the authors systematically summarized viewpoints of alien researchers on land suitability with GIS and classified the related methodologies into three aspects: Computer-assisted overlay mapping, multi-criteria decision-making methods and artificial intelligence methods. In addition, authors analyzed the latter two methodologies, put forward the orientation of more accuracy, integration and dynamics in this regard, and suggested to realize methodologies transition at different spatial scales and network assessment and evaluation visualization in the future.
