摘　　要：本文概述了我国东南丘陵区红壤退化现状、原因和治理意义,总结了30年来不同阶段红壤退化治理的成果,分析了红壤区域进一步发展现代高效生态农业的途径。论文提出针对红壤区域保障粮食安全、保护生态环境和应对全球气候变化的多重目标,在常规化学农业基础上,充分利用区域水热资源优势,融合生态农业、循环农业和智慧农业等模式的科学理念和优势,创新区域现代高效农业的建设原理、关键技术、配套政策法规和管理体系;针对红壤退化的区域特征,开展流域尺度红壤退化的综合治理和适度规模经营,建立红壤流域智慧农业发展模式,促进红壤区域农业现代化。The status quo and causes of red soil degradation in the hilly region of Southeastern China were described, and the significances to control and remediate the degraded red soil ecosystems were discussed. Then the achievements were summarized for the remediation of red soil degradation during last 30 years. Finally the ways to develop modem efficient ecological agriculture in red soil region were analyzed. Facing the multiple tasks of increasing food safety, protecting environment and responding to global climate change, we should take road to develop modem high-efficient ecological agriculture to make full use of regional advantaged resources of water and heat, in which the main steps are to improve the building principles, key technologies and supporting policies, regulations and management systems, and to integrate the advanced scientific concepts from different agricultural models, such as ecological agriculture, recycling agriculture and intelligent agriculture. Based on considering the regional characteristics of red soil degradation, comprehensively remediating the red soil degradation and developing moderate large-scale land management could be carried out at the basin scale, and the basin-scale intelligent agricultural models could be established to promote the agricultural modernization.
