摘　　要：采用2016—2022年衢江段实测江道重要断面及地形资料,系统分析衢江江道断面及江道容积变化、江道洪水水位变化及行洪过流能力。分析结果表明:近6年来,衢江江道容积总体稳定,警戒水位以下容积每年微增0.62%左右;断面总体变化不大,因航道疏浚等原因,局部稍有变化;江道洪水位变动不大,过流能力变化不明显;大洪水不改变衢江江道总体变化趋势;2016年之后建成的枢纽对衢江江道总体影响不大。Based on the measured data of major river sections and topographic data of Qujiang Section from 2016 to 2022,the paper systematically analyzes the changes of Qujiang section and river volume,changes of river flood level and flood discharge capacity.The analysis results show that:from 2016 to 2022,the volume of Qujiang River was generally stable,and the volume below the warning water level increased slightly by 0.62%every year.The overall change of the section was not significant,with some local slight changes due to channel dredging and other reasons.The river flood level did not change much,and the overflow capacity did not change significantly from 2016 to 2022.Major floods did not change the general trend of the Qujiang River;the water control complex built after 2016 had little impact on the overall Qujiang River channels.
