摘　　要：通过研究分析连江控制站高道站在飞来峡水库建成运行后近20年来的河道断面实测资料,发现该站河道断面在不断下切,前十年下切得比较严重,后十年比较平缓,最低河底高程也不断走低,分析结果对连江洪水预报、北江防汛抗旱、北江航运安全、水库下游供水、水库库区河床变化、水库上下游水资源水环境变化及水库防洪安全调度具有重要意义。Based on the research and analysis of the measured data of the river section of Gaodao station of Lianjiang control station in the past 20 years after the completion and operation of Feilaixia reservoir,it is found that the river section of Lianjiang control station is constantly undercutting,the undercutting in the first ten years is more serious,the undercutting in the last ten years is more gentle,and the lowest river bottom elevation is also continuously decreasing.The analysis results are of great significance to lianjiang flood forecast,Beijiang flood control and drought resistance,Beijiang shipping safety,It is of great significance for the water supply in the lower reaches of the reservoir,the change of riverbed in the reservoir area,the change of water resources and water environment in the upper and lower reaches of the reservoir and the safe operation of reservoir flood control.
