| 摘 要： | 以1960～2009年渭河下游各站实测数据为基础,分析了渭河下游水沙变化的情况,并利用Mann-Kendall法和距平累积法,对华县站年均来水来沙序列进行趋势分析。分析表明,渭河下游的来水来沙呈现减少趋势,尤其近期减少趋势明显,年水量的变异开始于1988年,年沙量序列则没有明确的变异点。 |

| Abstract: | Based on the field data of runoff and sediment of the Lower Weihe River in the period of 1960~2009,variation of runoff and sediment load are analyzed,and this study employed Mann-Kendall method and Cumulative Anomaly method to detect tendency of water and sediment.It was found that runoff and sediment load has generally decreased during the periods,with significant decrease in recent years. |
| Keywords: | variation of water and sediment tendency Mann-Kendall method cumulative anomaly method Lower Weihe River |
