摘  要：
利用窟野河入黄控制站——温家川水文站1956-2012年降雨、径流、洪水、泥沙实测资料,采用线性趋势分析、滑动平均、累积距平、R/S分析、双累积曲线法等多种方法,分析了窟野河水沙变化特征,降水和人类活动对径流及输沙的影响。结果表明:1总体上,窟野河径流量和输沙量呈持续下降趋势。21世纪初,年径流量和输沙量下降显著,其值分别为多年均值的34.4%和5%;2受降水和人类活动影响,径流量和输沙量年际变化过程经历了3个阶段,其转折点分别是1979年和1997年;3降水对径流量和输沙量的影响越来越弱,而人类活动对其两者的影响日益增强,成为影响径流和输沙的主导因素;4温家川站径流和泥沙的Hurst指数分别为0.876 7和0.803 9,表明未来一段时间内窟野河径流量和输沙量变化趋势将与过去保持同一势态,有持续递减的特征。正确认识水沙变化特性及产生的原因可为流域水资源合理开发和综合治理提供科学依据。

摘  要：
The Wenjiachuan is the most important hydrological monitoring station on the Kuyehe.In this study,the authors analyzed runoff and sediment variation characteristics and influencing factors based on rainfall,runoff,sediment and flood data during 1956-2012.Different analyzing methods linear trend analysis,moving average method,accumulated variance,R/S analysis,and double mass curve were used comprehensively.The results showed that the multi-year change of runoff and sediment had a decreased tendency in all,and this trend was the most evident in the beginning of the 21 st century.The runoff and sediment affected by rainfall and human activities appeared three change periods in which the turning years were 1979 and 1997,respectively.The response of rainfall to runoff and sediment became weaken gradually,the human activities had growing impacts,and became the main reason.The Hurst index were 0.876 7and0.803 9for runoff and sediment respectively,which indicated that the decreasing trends in Kuye River runoff and sediment would continue in the future.Learning the reasons of the water and sediment changes can provide reference for the the appropriate water resources exploitation and the comprehensive treatment.
