摘要: 农业规模经营是实现农业现代化的重要路径。为了探讨丘陵山区农业规模化发展对于水土流失的影响机理。通过文献综述法梳理相关研究,分析现有研究存在的不足,并提出研究展望。综观前人的研究可以得知:(1)农业规模经营的效益、政策与推动机制等状况;(2)丘陵山区水土流失的影响因素乃为自然因素与人为因素交互作用的结果,以及农业活动对水土流失的影响;(3)水土流失的调查、监测与影响因素的评估方法及仿真模拟。最后,提出5点研究展望:(1)构建丘陵山区水土流失驱动力模型;(2)建立丘陵山区农业规模化对水土流失的影响评估指标体系;(3)甄别影响程度及其时空差异;(4)丘陵山区农业规模化的水土流失效应模拟反演;(5)提出丘陵山区水土资源可持续利用的农业规模化政策建议。以期对我国丘陵山区发展适度农业规模化与可持续发展研究提供科学参考。

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.
