摘要
本文介绍了南宁郁江水文基本情况,运用Excel回归拟合曲线分析了郁江流域含沙量、输沙量、径流量三者变化趋势,对三者进行了回归拟合分析,得出结论:郁江流域水沙关系平稳,水土流失现象呈现下降趋势。
In the paper,the basic hydrological situation of Nanning Yujiang is introduced. Excel regression fitting curve is utilized for analyzing change trend of sediment content,water conveyance and runoff in Yujiang River Basin. Regression fitting analysis is implemented on the three aspects. The following conclusion is obtained: water-sediment relationship is stable in Yujiang River Basin,and water loss and soil erosion phenomenon show a decline trend.
