摘要
植物根系对保持滨岸区域土壤岸滩的稳定性具有重要作用。本文从根系固岸机制、根系固岸的评价方法、植物根系与固岸抗蚀关系等几个方面对植物根系的固岸抗蚀作用进行了综述。在这些方面目前已经取得了许多富有价值的成果,但相比之下,西方国家处于领先地位,中国在这些方面的研究还较少,目前仍处于起步阶段。建议未来应加强植物根系季节或年际变化规律与岸滩侵蚀季节或年际变化规律研究的结合,以及植物地上部分管理措施对地下部分特性影响的研究。
Plant root system plays an important role in keeping the stability of bank and soil. This paper reviewed the mechanisms of plant root system in bank reinforcement and erosion resistance, the methodologies for evaluating the effect, and the relationships of plant root system with the reinforcement and resistance. Many valuable results in these research areas have been obtained, but compared with that in Western countries, the research in China is still rare and at preliminary stage. It was suggested that future studies should more focus on the change patterns of plant root system and beach soil erosion among seasons and years, and the effects of different management measures for plant above-ground parts on the characters of plant underground part.
