The progresses of sloping field erosion, study methods and of preventive measures are summarized. The mechanism and affect factors of sediment, runoff and nutrient loss on the slopeland surface are analyzed respectively. The sloping fields were the main source of sediment, runoff and nutrient loss. Most of the research works focused on the prevention soil and water loss on the slopeland surface and improvement of soil fertility. Most of the study methods were qualitative and statistics analysis. However, studies on the mechanism of soil and water loss and nutrient loss, the model of quantitative analysis were scarce yet, the further studies should pay more attention to the processes of runoff and sediment yield, so as to study the mechanism of slope erosion and build the process-based model of water erosion prediction.
