| 摘 要： | 从周期性、趋势性及持续性揭示了汉江上游石泉和安康水文站的径流规律.采用谱分析法对径流序列进行周期性分析得出了周期变化规律,应用Kendall秩次相关检验分析径流序列的演变趋势性获取了两站径流序列递减趋势,用R/S分析法计算了H指数两站径流序列均具持续性状态.分析结果将为汉江上游水资源开发利用提供科学依据.

| Abstract: | Runoff law of Shiquan and Ankang hydrological stations in the upper Hanjiang River is studied in this paper from three aspects including periodicity,tendency and sustainability of tendency.Firstly spectrum analysis method is adopted to analyze periodicity of runoff time series and periodicity change law is obtained.Then Kendall rank correlation coefficient test is adopted to analyze the development tendency of runoff time series.The results show that runoff time series of two stations have decreasing tenden... |
