摘要
以贵阳水文站近45年年径流量时间序列为例,借助于Excel和MATLAB等软件,利用滑动平均法、累积距平法、Mann-Kendall趋势检验法及变差系数对南明河流域贵阳水文站径流量时间序列进行了计算分析。结果表明:1990-2000年贵阳站年径流量系列的具有显著的上升趋势;年径流量系列的变差系数较小,径流变化比较稳定,有利于水资源的开发利用。以期对喀斯特地区水资源规划及可持续利用具有参考意义。
The time series of annual runoff at Guiyang Hydrological Station in the recent 45 years is used as an example.By means of software such as Excel and MATLAB,the time series of runoff at Guiyang hydrological station in Nanming River Basin are calculated and analyzed by using the moving average method,the cumulative anomaly method,Mann-Kendall trend test and the coefficient of variation.The results show that the annual runoff series has significant upward trend at Guiyang Hydrological Station during 1990 to 2000,because the coefficient of annual runoff series is small,runoff is relatively stable,which is conducive to the development and utilization of water resources.The author hopes that this study will serve as a reference for water resources planning and sustainable use.
