渭河流域水文变异综合诊断分析研究

Comprehensive Diagnosis and Study on Hydrological Variation of Weihe River Basin

水文序列受水文气象条件改变和人类活动的影响,变化趋势已愈发明显。水文时间序列参数的变化对河流的多年平均径流量有直接影响,对人类生产生活有着十分重要的意义。文章将渭河流域的水文时间序列数据带入不同模块,结合不同诊断方法综合对比分析得出流域年径流量的变异点,所得成果对流域水文变异综合诊断分析具有重要的参考价值。

Influenced by the changes of hydrometeorological conditions and human activities,the hydrological sequence has become more and more obvious.The changes of hydrological time series parameters have a direct impact on the average annual runoff of rivers,which is of great significance to human production and life.In this paper,the hydrological time series data of Weihe river basin are brought into different modules,and the variation points of annual runoff in the basin are obtained through comprehensive comparative analysis of different diagnostic methods.The obtained results have important reference value for the comprehensive diagnosis and analysis of hydrological variation in the basin.
