摘要

根据渭河流域水文站点分布特征，将流域划分为15个子流域，结合1961—2015年输沙资料和气象站日降雨量资料，采用Mann—Kendall检验、双累积曲线、相关性分析及偏最小二乘回归等方法，定量分析渭河流域输沙时空变化特征及其主控因子。结果表明：渭河流域1961—2015年输沙量呈显著减少趋势，渭河干流咸阳站、北洛河状头站和泾河张家山站年输沙量分别以0.039 0，0.017 4，0.041 4亿t/a的速率减少。15个水文站中，北洛河的张村驿站年输沙量呈显著增加趋势（P<0.05），洪德、雨落坪和庆阳站呈不显著减小趋势，其余各站的输沙均显著减小（P<0.05）。主要通过对输沙驱动因子和渭河流域输沙模数2个方面进行纵横方向上的综合分析对比，最终得到的相关数据结果表现出渭河输沙变化与降雨集中度指数、植被覆盖指数、草地面积比例、最小高程、平均坡度等因子具有良好的相关关系（R2>0.7）。

Abstract

In recent years

sediment load in many rivers around the world has undergone significant changes

which may greatly affect ecological environment and economic development of the basin. Exploring the evolution of sediment load in the Weihe River will provide a theoretical basis for the comprehensive management of the Weihe River Basin and the regulation of water and sediment relations. This study attempted to investigate the spatial and temporal variation of sediment load in 15 hydrological stations in the Weihe River basin during the period of 1961-2015. The results showed that the average sediment load in the Weihe River Basin from 1961 to 2015 showed a significantly decreasingtrend. The annual sediment load atXianyang

Zhuangtou and Zhangjiashan stations decreased at a rate of 0.039 0 billion t/a

0.017 4 billion t/a

and 0.041 4 billion t/a

respectively. Among the 15 hydrological stations

the annual sediment load atZhangcunyistation showed a significant increasing trend

while Hongde

Yuluoping and Qingyang stations showed no significant decreasing trend

and the remaining stations showed significant decreasing trends (P<0.05). Both correlation analysis and partial least squares regression were applied to quantify the relationship between sediment load and potential driving factors. The sediment loadhad good correlations with the Precipitation Concentration Index

Vegetation Coverage Index

Grassland Area Ratio

Minimum Elevation

and Average Slope.
