在小流域水利工程设计中,由于泥沙监测资料少,给水利工程设计带来不便.现通过对一元回归模型原理及显著性进行分析,结合西台峪小流域实验站多年输沙监测资料,建立年输沙模数与年降水量的相关关系,并对其相关性进行检验.根据该小流域实验资料建立的相关关系,在附近流域进行水利工程设计时,在下垫面因素比较相似的情况下,可以移用该流域相关关系计算年输沙模数.
在小流域水利工程設計中,由于泥沙鑑測資料少,給水利工程設計帶來不便.現通過對一元迴歸模型原理及顯著性進行分析,結閤西檯峪小流域實驗站多年輸沙鑑測資料,建立年輸沙模數與年降水量的相關關繫,併對其相關性進行檢驗.根據該小流域實驗資料建立的相關關繫,在附近流域進行水利工程設計時,在下墊麵因素比較相似的情況下,可以移用該流域相關關繫計算年輸沙模數.

During the design of water conservancy project in small watershed, the lack data of sediment transport monitoring caused discommodi-ties.Having analyzed the unary regression model principium and significance with years' sediment transport monitoring data of Xitaiyu experiment station in small watershed, the correlativity between the modulus of annual sediment transport, and annual precipitation was established, which was conducted on correlation test.According to the corretativity of the data about this experiment,this watersheds correlativity can be used to calculate annual sediment transport modulus when underlying surface factors are quite alike in the design of water conservancy project near watershed.
