Method and system for analyzing and evaluating thermal stratification evolution trend of stratified reservoir based on wavelet transformation

The invention discloses a method and system for analyzing and evaluating the thermal stratification evolution trend of a stratified reservoir based on wavelet transformation, and the method comprises the steps: selecting water temperature and water level monitoring points of surface-middle-low layers of the reservoir, and selecting the layout position and layout mode of an electronic weather station; collecting surface-middle-low layer water temperature long sequence data of a target reservoir, and collecting air temperature-radiation long sequence data; based on the water temperature data of the target reservoir, wavelet transform analysis is carried out, a wavelet transform result of surface-medium-low layer water temperature and air temperature-radiation is obtained, a schematic diagram is drawn, and typical thermal stratification reservoir thermal stratification formation-stabilization-extinction trend analysis and evaluation are carried out; and adjusting the variation amplitude of the air temperature-ra
