广东热带沿海侵蚀地的植被恢复途径及其效应

依据热带自然林的种类组成、层次结构多样性的特点， 以及植物群落的演替规律， 在百余年水土流失严重的不毛荒坡上， 开展了植物的引种和群落配置研究。25年来， 采取工程措施与生物措施相结合， 选用耐旱、耐瘠、速生的先锋树种， 进行荒山绿化， 重建先锋群落。建立了6000余亩多样性的热带人工林样板。初步探索出从荒坡恢复到多层多种阔叶混交林的途径。对同类沿海侵蚀地的改造利用， 有指导意义。Based on the species composition, hierarchical structural diversity of tropical natural forests, and the succession patterns of plant communities, this study conducted research on plant introduction and community configuration on barren hillsides that had suffered from severe soil and water loss for over a century. Over the past 25 years, by integrating engineering and biological restoration measures and selecting drought-tolerant, infertile soil-tolerant, fast-growing pioneer tree species, we carried out afforestation on barren hills and reconstructed pioneer plant communities. A 6,000-mu demonstration plot of diverse tropical plantation forests was established. This study preliminarily explored the pathway to restoring barren hills into multi-layered, multi-species broad-leaved mixed forests, and provides valuable guidance for the rehabilitation and utilization of similar coastal eroded lands.
