Identifying Spatial Patterns of Land Use and Cover Change at Different Scales Based on Self-Organizing Map

There are many complicated and non-linear spatial patterns on land use and cover change at different scales. It is very difficult to express these geographic phenomena at a known scale. The aim of this paper is to propose self-organizing map to identify spatial pattern of land use and cover change at different scales. The procedure and steps of identifying spatial pattern of LUCC based on SOM are discussed in detail. An example of application research is experimented in Echeng District through remote sensing imagines in 1992 and 2002. The results suggest that SOM is very distinct and visual, which can avoid too many clusters to misty spatial pattern or be short of clusters so as not to express its change diversity.
