A typical small watershed in Sanxia area-Chenjiagou small watershed as the research object, spatial and attribute database were constructed for SWAT model of Chenjiagou small watershed. The spatial database was constructed based on the processing the topographic map digitally, re-encoding the land use pattern and sub-dividing the customized soil type. The attribute database was constructed by looking at the'soil species in Wanx-ian area', using software and empirical formula for calculating and using measurement and investigated data. The SWAT model based database construction can be the foundation in application of the model in this water-shed.
