南方红壤区草被的水土保持功能研究进展

Review of the Function of Grass on Water and Soil Conservation in Red Soil Region in South of China

摘要: 种草是水土保持植物措施的重要组成部分, 在南方水土流失区生态恢复与重建中具不可替代的作用。根据前人的研究, 阐述草被发生水土保持作用的主要部位, 介绍现阶段草地、牧草套种 (间作) 、草篱的水土保持应用情况与成效, 提出南方红壤区草的水土保持应用研究的若干思考: (1) 广泛收集水土保持草本植物资源; (2) 加强水土保持草种选育与评价体系构建; (3) 开展严重侵蚀劣地草被建植关键技术攻关研究; (4) 加快侵蚀果茶园水土流失治理与示范; (5) 开展水土流失区草业发展关键技术研究。
