【 摘 要 】

Soil erosion is a very complicated process. This paper uses convolution theory, through the runoff and sediment data of economic forest area natural rainfall conditions of southeast coastal area collected, and divided into several micro slope unit, using convolution model, slope soil erosion analysis. The simulated values were verified with the measured values, the results show that the simulated values and measured values of the average relative error is 40%, the effective model coefficient is 0.614; the simulation value had a significant linear relationship with rainfall and runoff.
