| 摘 要： | 北洛河流域是黄河粗泥沙的主要来源区之一.基于北洛河流域(氵状)头水文站1950-2006年逐年降水量、径流量和输沙量数据,分析了北洛河径流与输沙变化特征.Mann-Kendall、Spearman检验以及线性趋势拟合均表明,降水量、径流量和输沙量均呈显著减少趋势;利用单位降水产流产沙量距平累积曲线分析表明,北洛河单位降水产流产沙量变化可以分为枯水平沙期、丰水丰沙期、枯水平沙期、丰水枯沙期、丰水丰沙期和枯水枯沙期等6个阶段.分析其变化原因认为,降水是影响径流输沙变化的主要自然因素,其中降水径流关系最为密切;水利水保措施的实施、毁林开荒、修路开矿等破坏活动、国家政策以及法律法规的颁布实施等人类活动同样影响径流、输沙量的变化. |

| Abstract: | The Beiluo River basin is one of main source regions to produce coarse sediment for the Yellow River.The basic characteristics of precipitation,runoff and sediment (from 1950 to 2006) were analyzed.The results showed that the precipitation,runoff and sediment had an obvious decreasing trend and the change of runoff and sediment has six obvious periods.The analysis on the reasons for these changes showed that the precipitation is the main natural factor,while the human activities also have an important effect on the change of runoff and sediment. |
| Keywords: | the Beiluo River runoff sediment reason analysis |
