| Abstract: | Identification of trends in long term time series of hydro-meteorological variables is an important topic for better understanding the effects of climate change and human activity on hydrological processes. In this study,data from five meteorological variables at eight stations in the upper and middle reaches of Heihe River Basin were analysed and the non-parametric Mann-Kendall test was employed to investigate their trends over the past years. It was found that on the annual scale,time series of average te... |
