借鉴国内外土壤侵蚀建模的经验与技术，针对我国干旱地区的实际情况，应用微机技术，建立了坡耕地土壤侵蚀过程数学模型ＳＬＥＭＳＥＰ，并在晋西北砖窑沟试验区得到了验证。模拟过程以天为步长，可预报不同耕作措施条件下，基于日降水量的坡面土壤侵蚀量，定量评价人类活动对土壤侵蚀过程的影响，为水土保持的决策和具体措施的制定提供依据。ＳＬＥＭＳＥＰ模型可进行长期模拟，应用于土壤变化和可持续利用的研究。
According to the experience and technology of soil erosion modeling both at home and abroad, aiming at the actual situation of arid areas in our country, the mathematical model SLERSEP of soil erosion in sloping arable land was established by microcomputer technology and verified in the experimental area of brick kiln ditch in northwestern Shanxi province. The simulation process takes days as a step, and predicts the amount of soil erosion based on daily precipitation under different tillage measures, quantitatively evaluates the influence of human activities on soil erosion process, and provides the basis for making decisions and specific measures for soil and water conservation . The SLEMSEP model can be used for long-term simulation and applied to the research of soil change and sustainable utilization.
