The invention discloses an urban ecological toughness evaluation and early warning method and device and related equipment, and the method comprises the steps: S1, obtaining real-time data from an urban ecological environment, and forming a time sequence; s2, on the basis of the determined time width, performing smooth noise reduction processing and standardization processing on the time sequence data; inputting the data into an Informer model, and evaluating a future ecological toughness value; s3, on the basis of an Isolation Forest model, ecological toughness original historical data are calculated by using the monitoring data after smoothing processing, an alarm threshold interval is set, and when a predicted toughness value is in the alarm threshold interval, a system sends out low-toughness early warning; and S4, analyzing low-toughness data indexes, and giving a corresponding specific disaster early warning method through historical situations. The method can improve the reasoning ...
