摘　　要：弯曲河流是自然界存在河流的基本形态,研究河流曲度对河流生物多样性的影响,能够深入认识弯曲河流的生态功能。在大量文献研究基础上,梳理了河流曲度—生物栖息地、水流条件—生物多样性之间的相关关系以及裁弯取直工程和河流修复工程对河流生物多样性影响等研究的进展。目前,研究仍停留在定性和半定量层面上,尚未有学者全面系统地开展河流曲度与生物多样性相关关系的定量研究。提出今后应进一步开展理论和系统研究,探索河流曲度对生物多样性影响的机理,寻求有利于生物多样性增长的适宜河流曲度范围。Curvedriver is basic form of the river in nature. It is necessary to make further research on the impact of river sinuosity on river biodiversity and can help us to understand river ecological function thoroughly. Based upon reviews of the former researches on leisure, this thesis had clarified the correlation of sinuosity habitat and flow conditions biodiversity and described the research progress of the impact of the cutoff and restoration works on the river. At present, the research still remains at the qualitative and semi-quantitative level. There is no quantitative research on the correlation of sinuosity and biodiversity. Based on the above description, in the future, we should further study on theory and system, explore the mechanism of river sinuosity effects on biodiversity and search the optimal range of river sinuosity for the in-crease of biodiversity.
