[目的]构建南方红壤丘陵水土流失防控与循环农业模式,并分析其应用效果。[方法]分析我国南方红壤山地水土流失的成因和长期治理却收效不显著的原因,提出南方丘陵水土流失区综合防控的基本思路,并在此基础上进一步分析各种模式的关键技术、经济效益、生态服务功能和固碳增汇效果。[结果]南方丘陵水土流失区综合防控的基本思路即:将水土流失防治与现代农业生产相结合,构建“果(茶)-草-畜-沼”水土流失综合防控的循环农业模式;应用效果分析表明,在南方丘陵区建立循环农业模式以防控水土流失效果显著,能同时满足生态、经济和社会效益的协调发展。[结论]该研究建立了一种适合南方红壤山地水土流失治理与农业保护性开发的有效模式,可带动山区生态恢复与乡村农业经济的可持续发展。
[Objective] The purpose was to construct soil erosion prevention and control and cycling agriculture pattern in hilly red soil region in southern China and analyze its application effect. [Method] The causes of soil erosion in the red soil mountainous areas of southern China and the reasons for their insignificance in long-term treatment were analyzed. The basic idea of integrated prevention and control in the hills and hills of the southern hills was put forward. On the basis of this, the key technologies of various modes and economic Benefit, ecological service function and carbon sequestration effect. [Result] The basic idea of comprehensive prevention and control of hill and hillside soil erosion area in southern China was to combine the prevention and control of soil and water loss with modern agricultural production, and to build a recycling agriculture with integrated control of soil and water loss The application effect analysis shows that the establishment of a circular agriculture model in the southern hilly region to prevent and control soil erosion is effective and can simultaneously meet the coordinated development of ecological, economic and social benefits. [Conclusion] The study established an effective model for soil erosion control and agricultural development in southern red soils, which could promote the sustainable development of mountainous area ecological restoration and rural agricultural economy.
