摘要：Soil erosion is very serious in Thailand especially in northern Thailand. Important on-side effects of soil erosion may be the decline in qualities of soil related to agricultural productivity. So it is very important to assess the soil erosion risk for the sustainable development of agriculture. This study was conducted with objective of modelling and assessing soil erosion risk in the northern Thailand with the application of IMAGE\LDM. Rainfall erosivity index, relief index, soil erosivity index and land cover index are four basic factors used in IMAGE\LDM. Soil erosion risk can be grouped into six classes. Furthermore, the spatial distribution characteristics were also analyzed with the application of GIS in the view of elevation, land use types. From the result we can find soil erosion risk is high in the altitude between 100 and 400. Soil erosion risk is lower in the forest area than in the agriculture and plantation area
