[Objective] To design the soil-electric-acoustic sand table model in order to provide a more intuitive dynamic demonstration model for soil and water conservation education. [Methods] Based on the characteristics of a small watershed

the type of soil erosion

and soil and water conservation measures were demonstrated with the light

electricity and sound system. The soil erosion intensity

the soil and water conservation measures and the monitoring of soil and water conservation were demonstrated with the aid of the miniature artificial rainfall system. [Results] The soil-electronic sand table model was actually a simplified small watershed

which was divided into 12 large demonstration areas. The model focused on the expression of topography

terrain and geographical characteristics of natural elements. It could demonstrated the watershed boundary and its relations with adjacent watersheds

the basic elements of watershed system

biological and engineering measures for soil and water conservation

hydrological network system composition and concentration process. [Conclusion] The soil-electronic-acoustic model could provide an emulative

interesting

experience

autonomic and interactive model for soil and water conservation teaching

and could enhance the students' learning interest and initiative

and improve the teaching effect.
