Abstract: Large-scale agriculture management is an important method to implement agricultural modernization. This study aims to explore the influential mechanism of large-scale agriculture in hilly areas on soil erosion using literature review. All related studies are collected and organized. New research perspectives are then established based on the analysis of the disadvantages found in current studies. To sum up the previous studies, we learn a) the efficacy, policy and promotion mechanisms of large-scale agriculture management; b) that soil erosion is a result of the interaction between natural and artificial factors based on agricultural activities; and c) the methods to investigate and monitor soil erosion as well as evaluations and analog simulations of influential factors. Finally, five research perspectives are proposed: a) establishing a driving force model for soil erosion in hilly areas; b) setting up an evaluation index system based on the influence of large-scale agriculture in hilly areas on soil erosions; c) analyzing the influential level and spatial-temporal difference; d) inversely simulating the soil erosion effect caused by large-scale agriculture in hilly areas; and e) suggesting the policies made for large-scale agriculture in hilly areas that acquire sustainable soil and water resources, which are expected to serve as valuable scientific references to appropriate large-scale agriculture in hilly areas and sustainable development.
