Non-point source pollution in agriculture has become an important factor restricting the sustainable development of economy, society and environment and has a direct impact on people’s drinking water and food security. The paper introduced the concepts of soil erosion and agricultural non-point source pollution, and pointed out that soil erosion is an important form of agricultural non-point source pollution and transport carrier. On the basis of summarizing the influencing factors of soil and water loss, this paper puts forward the countermeasures of prevention and control of soil and water loss and gives some suggestions on the research of soil and water loss and agricultural non-point source pollution.
