摘　　要：选取渭河下游主要控制站咸阳站、临潼站、化县站,分别统计三站在渭河综合治理前(1974~2010年)和综合治理后(2011~2014年)水沙情况、河道造床流量及过洪能力等数据,通过综合治理前后特征数据对比的方法反映造床流量及过洪能力的变化情况,结果表明:综合整治后,随着堤防的加高培厚及新建,河道的造床流量和过洪能力大大增加。To select Xianyang station, Lintong station and Huaxian station, the main control stations in the lower reaches of Weihe River, and collect statistics of water and sediment discharge, riverbed flow and water balance before comprehensive treatment （1974-2010） and comprehensive treatment （2011 - 2014） of three stations respectively Flood capacity and other data. Through the comparison of the characteristic data before and after the comprehensive treatment, it can reflect the changes of the flow rate and the flood capacity. The results show that with the improvement of the embankment and the new construction, Flood capacity has greatly increased.
