Abstract

Due to the influence of global warming and environmental change, the meteorological and hydrological elements of the Dagu River Basin have also undergone a series of response changes, which have led to the change of the spatial and temporal changes of water resources. The natural ecological environment and the economic development of human society have been seriously affected. In this study, hydrological and meteorological factors such as temperature, precipitation, evaporation and runoff were selected as the object of study. Spearman order correlation test, linear regression method and sliding average method were used to analyze the trend of meteorological hydrological elements in Dagu River Basin in Recent 50 Years. The results show that the trend of climate warming in Dagu River Basin is consistent with that of national climate change in recent 50 years. At 0.05 confidence level, the annual mean temperature fluctuates with time, and the annual precipitation is increasing with time. The trend of declining trend is not significant. The annual evaporation decreases with time, and the descending trend is significant. The surface runoff decreases with time.
