Promote Development of Modern High-Efficient Ecological Agriculture Based on Divisional Remediation of Red Soil Degradation in Hilly Region of Southeastern China
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 modern 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 modern 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.
