The present invention provides a thermocline monitoring method based on spectral technology and a thermocline monitoring device based on spectral technology. The method first pre-judges whether a thermocline exists through temperature monitoring points, and then determines whether a thermocline exists through spectral analysis of water quality monitoring points. If so, the height of the thermocline is calculated based on the coordination of temperature monitoring points and water quality monitoring points. The method has high accuracy and can timely and accurately process the thermocline according to the height of the thermocline.
