摘要
由于红壤的生态脆弱性及亚热带的暖湿气候特征,亚热带红壤区已成为自然生态系统破坏与退化的严重区域,亚热带红壤的退化机理及恢复与重建成为土壤学、水土保持、生态学研究的热点问题之一。综述了近年来有关红壤退化的过程、机理及影响因素等方面的研究进展,并提出了退化红壤的生态恢复及重建的技术措施。
The red soil region of subtropics is one of the most densely populated areas in China in which natural ecosystem has been heavily destructed and degraded to ecological weakness and climatic characteristics. The research of degradation, restoration and reconstruction in these regions has become one of the hot points in soil science, water and soil conservation science and ecology. The research has concentrated on causes, process, mechanism and features of soil degradation. The ecological restoration about degraded red soil was discussed.
