| 摘 要： | 为了研究渭河上游径流演变特性，以林家村等5个水文站近50 a的实测径流序列为基础，采用Mann-Kendall趋势分析法(M-K法)和R/S法分析了径流演变趋势。结果表明：渭河上游径流年内分配在20世纪50年代较为集中，60~90年代相对均匀；径流年际变化较大；径流量总体呈下降趋势，且趋势性较为显著。研究成果为渭河流域水资源开发利用、调度管理和生态环境保护提供一定参考。

| Abstract: | In order to analyze the runoff evolution characteristics of upper Weihe River,the runoff variation trends of 5 hydrological stations of Linjiacun etc.are analyzed using Mann-Kendall method and R/S method on the basis of measured runoff series data for 50 years.The results show that the annual distribution of runoff in upper Weihe River is concentrated relatively in 1950s,relatively even during 1960 to 1990;the inter-annual variation is large;the runoff is reducing generally,and the trend is obvious.The results can provide a reference for the development,utilization,regulation and management of the water resources and ecological environment protection of Weihe River. |
