Abstract: 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.
