Abstract The abandoned dreg sites of production and construction project is variety, the composition and structure of waste slag is complex, thus, different sites have different erosion form, the mechanism is not same too. The soil and water loss in abandoned dreg field is very serious, which leads hard to implement appropriate soil and water conservation measures. Based on the demonstration and classification of soil erosion type and its characteristics’analysis, the main factors influenced soil erosion in abandoned dreg site were pointed out to be row of abandon way, material composition, slope and accumulation time etc. Combining with abandon dreg field water loss and soil erosion control goal,ensuring stability and safety of the abandoned dreg field, and restoring the land productivity, this paper analyzed the current soil and water conservation measures’characteristics and gave advices in establishing and perfecting measures system of soil and water conservation in abandoned dreg field, which provided a scientific basis and guidanc for controlling the soil and water loss.
