[0057] In order to show the purpose and technical solutions of the present invention more clearly, taking the Xiaolangdi Hydrological Station of the Yellow River as an example, the present invention will be further described in detail in conjunction with the accompanying drawings. The specific implementation steps are as follows figure 1 :
[0058] Step 1. Collect the yearly daily discharge data of the Yellow River Xiaolangdi Hydrological Station from the "Hydrological Yearbook of the People's Republic of China". Daily traffic data was collected from 1956-2015. Since the Xiaolangdi Reservoir was officially put into use at the end of 2001, the time series were divided into time series before the reservoir was built (1956-2001) and time series after the reservoir was built (2002-2015).
[0059] Step 2, based on the daily flow time series (1956-2001) of the 46 years before the establishment of the database, taking January 1st as an example, from the 46 data composed of the flow ra...
