摘　　要：糯扎渡电站是澜沧江流域最大的电站、同时也是澜沧江中下游梯级开发的核心工程,研究其库区的泥沙淤积对研究整个流域的泥沙淤积情况具有较大的指导意义。采用历史水文数据,结合水文比拟法和Brune模型,计算出糯扎渡电站库区泥沙淤积量。结果显示:糯扎渡电站库区的泥沙淤积量分别为2016年7800×10^(4) t、2017年9534×10^(4) t、2018年6982×10^(4) t、2019年6178×10^(4) t,年平均淤积量为7623×10^(4) t。The Nuozhadu hydropower station is the largest hydropower station in Lancang River basin,and also the core project of cascade development in the middle and lower reaches of Lancang River.The study of sediment deposition in reservoir is of great significance to the study of sediment deposition in the whole basin.Based on historical hydrological data,combined with hydrological analogy method and Brune model,sediment deposition in Nuozhadu hydropower station reservoir was calculated.The results showed that:the sediment deposition of Nuozhadu hydropower station reservoir were 7800×10^(4) t in 2016,9534×10^(4) t in 2017,6982×10^(4) t in 2018 and 6178×10^(4) t in 2019,with an averaged annual sediment deposition of 7623×10^(4) t.
