【摘要】：農(nóng)業(yè)規(guī)模經(jīng)營是實現(xiàn)農(nóng)業(yè)現(xiàn)代化的重要路徑。為了探討丘陵山區(qū)農(nóng)業(yè)規(guī)模化發(fā)展對于水土流失的影響機理。通過文獻綜述法梳理相關(guān)研究,分析現(xiàn)有研究存在的不足,并提出研究展望。綜觀前人的研究可以得知:(1)農(nóng)業(yè)規(guī)模經(jīng)營的效益、政策與推動機制等狀況;(2)丘陵山區(qū)水土流失的影響因素乃為自然因素與人為因素交互作用的結(jié)果,以及農(nóng)業(yè)活動對水土流失的影響;(3)水土流失的調(diào)查、監(jiān)測與影響因素的評估方法及仿真模擬。最后,提出5點研究展望:(1)構(gòu)建丘陵山區(qū)水土流失驅(qū)動力模型;(2)建立丘陵山區(qū)農(nóng)業(yè)規(guī)模化對水土流失的影響評估指標(biāo)體系;(3)甄別影響程度及其時空差異;(4)丘陵山區(qū)農(nóng)業(yè)規(guī)�；乃亮魇�(yīng)模擬反演;(5)提出丘陵山區(qū)水土資源可持續(xù)利用的農(nóng)業(yè)規(guī)模化政策建議。以期對我國丘陵山區(qū)發(fā)展適度農(nóng)業(yè)規(guī)模化與可持續(xù)發(fā)展研究提供科學(xué)參考。
[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.
