This study attempts to quantitatively investigate the relatinship between agricultural land use and environmental factors through synthsizing various types of spatial data. The study area is the Tokachi Plain in eastern Hokkaido, Japan. In this analysis, data were transformed from raster data to vector data, creating a synthesizing data bank. Next, this study clarified the relationship between several types of spatial data in detail. In this study, agricultural land use was classified into rice, wheat, root crops and beans, crops for industrial processing, vegetables, feed crops, and horticulture. Environmental factors included altitude, slope angle, slope aspect, geomorphology, surface geology, soil type, temperature during the summer, and precipitation during the summer. In the overlay analysis of agricultural land use and these environmental factors, it was clarified that the land use type was determined by the geomorphology, the surface geology, and the temperature during summer in the Tokachi Plain. In future, agricultural planning will have to rely more and more upon data banks synthesized from various data sources. Correspndingly, the development of synthesizing techniques is of great importance for decision making.
