南方红壤对农业乃至整个经济的可持续发展和人民生活水平的迅速提高起着重要作用。但红壤具有酸、薄、粘等弱点，区域内降水时空分布不均，加之不合理的开发利用，导致红壤区水土流失、退化、污染和生态环境恶化，红壤资源的潜在生产能力没有得到适当发挥，严重影响了整个农业和经济的可持续发展。当前，我国南方红壤生态系统面临着水土流失、酸化、肥力退化、季节性干旱、土壤污染、生物退化、土地沙化、土地沙化、耕地减少和系统功能衰退等问题，针对这些问题，需要提高综合治理意识，调整农业结构，优化耕作制度，发展立体农业，治理水土流失和污染，提高土壤质量和肥力，重建红壤植被生态系统，建立和完善红壤预警系统，确保南方红壤生态系统稳定健康发展。
Southern red soil plays an important role for sustainable development of agriculture,even the whole economy, and the rapid increase in people' s living standard. But red soil has some weakness,such as acid,thin and sticky,the uneven temporal distribution of precipitation in the region,and the irrational exploitation which leading to soil erosion, degradation,contamination and deterioration of ecological environment in red soil areas,the potential production capacity of red soil resources are not properly exert,and the entire agriculture and sustainable economic development are severely affected. Currently,China Southern red soil ecosystem faces many problems,such as soil erosion,acidification,fertility degradation,seasonal drought,soil pollution,biological degradation,desertification,land desertification,reduction of arable land and system functions decay and so on. In response to these problems,we need to raise awareness of comprehensive measures,to adjust the agricultural structure,optimize the farming system,develop three-dimensional agriculture,control soil and water erosion and pollution,improve soil quality and soil fertility,reconstruct vegetate ecosystem of red soil,establish and improve red soil early-warning system,so as to ensure steady and healthy development of the southern red soil ecosystem.
