摘要：Spatial analysis has being a hot issue in spatial information science. However, its lack of unified principles and systematic technology make its development lag behind applications’ needs. This paper introduces field concept to spatial analysis, proposes the theoretical framework of spatial analysis based on data field, constructs land gradation data field, discusses spatial analysis techniques based on land gradation data field (including classification of data fields’ sources, recognition of radiation pattern, determination of field strength, and attenuation model), and builds land gradation model. Research on urban commercial land gradation method based on land gradation data field is performed with case study in Wuhan, China. The gradation result is assessed to be reliable and authentic
