摘要
根据水文学统计原理,以石河水库站汛期径流量和悬移质年输沙量的同步实测资料为依据,建立相关曲线,通过相关系数计算和显著性水平的检验以及误差评定,给出回归预测模型,为延长石河水库站悬移质输沙量系列长度提供有效的理论依据,为实际预测今后石河水库站的年输沙量,在方法和精度上提供了保证。
According to statistical theory of hydrology, basing on the synchronous measured date of the runoff in flood season and annual suspen ded load o~ sediment discharge in Shihe reservoir hydrological station, a related curve was estab~,ished. Through the correlation eoef{icient caleulw tion, the significance level inspection and the error evaluation,regression prediction model is given. It can provide effective theoretical basis for extending the length of sediment discharge of suspended load series and give security in the method and accuracy for the actual prediction of an nual sediment discharge in Shihe reservoir hydrological station.
