【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]:Agricultural scale management is an important way to realize agricultural modernization. In order to explore the influence mechanism of agricultural scale development on soil erosion in hilly and mountainous areas. Through literature review, this paper analyzes the deficiency of the existing research, and puts forward the research prospect. From the previous studies, we can see that the benefit, policy and promotion mechanism of agricultural scale management are the result of interaction between natural factors and human factors in hilly and mountainous areas, and the influencing factors of soil and water loss in hilly and mountainous areas are the result of interaction between natural factors and human factors. And the influence of agricultural activities on soil and water loss. The investigation of soil and water loss, the evaluation method of monitoring and influencing factors, and the simulation. Finally, This paper puts forward a 5 point research prospect: 1) constructing the driving force model of soil and water loss in hilly and mountainous areas. (2) establishing an index system for assessing the impact of agricultural scale on soil and water loss in hilly areas; (3) discriminating the degree of influence and its temporal and spatial differences; 4) agriculture in hilly areas In this paper, the agricultural large-scale policy recommendations for sustainable utilization of soil and water resources in hilly and mountainous areas are put forward. In order to provide scientific reference for the study of moderate agricultural scale and sustainable development in hilly and mountainous areas of China.
