The application of GIS technology to land evaluation in China began much later than in other countries. But it is developing very rapidly. So far, GIS has been used mainly as an assistant in evaluation of land resources. Beginning with addressing models and methods for land evaluation, the authors divided the GIS-based land evaluation research into three types, i.e. single-region nonspatial model, single-region spatial model, and multi-region model based on interactions between land evaluation units and unicity or not of the evaluation region. The application of GIS and its related technologies may reveal the static or dynamic interactive effects between land evaluation units. This paper is a review of the three types of research, summarizing systematically advances in the research on GIS-based land evaluation in the country.
