郁江南宁站水沙变化的回归分析

Regression Analysis between Discharge and Suspended Sediment Discharge at the Nanning Gauging Station of Yujiang River

根据郁江南宁站1954～2001年的流量和输沙率资料,对流量和输沙率之间进行了回归分析,得出了多年平均月均流量-输沙率的相关性、各年月均流量-输沙率的相关性、各月月均流量-输沙率年际变化的相关性和年均流量-输沙率的相关性,分析了南宁站的水沙变化趋势,得出了两者变化趋势的规律。

Based on the data of discharge and sediment in Nanning Gauging Station of Yujiang River from 1954 to 2001, the regression analysis between the discharge and the suspended sediment discharge has been made in order to understand the correlation between the suspended sediment discharge and the mean multi -year discharge of each month, the mean monthly value of each year, the mean value of each month, the mean yearly value. Analyzing the discharge and sediment variation at Nanning Gauging Station of Yujiang River has drawn out the principle of the variation trend for discharge and sediment.
