摘　　要：基于蜿蜒型河流丰富的地貌异质性,回顾了蜿蜒型河流形成机理及影响因素,论述了蜿蜒型河流的地貌结构和动态变化特征,总结了地貌异质性的生态功能,重点分析了深潭-浅滩序列结构的相关研究进展,归纳了蜿蜒型河流异质性的生态学意义。Based on abundant geomorphological heterogeneities in meandering river,the shaping mechanism of meandering rivers and its influence factors are reviewed; geomorphological structure of a meandering river and its dynamic change features are discussed; and the ecological functions of geomorphological heterogeneities are summarized. Pool-riffle sequence and its relevant researches are mainly analyzed. The ecological significance of various geomorphological characteristics in meandering river is summed up.
