The invention discloses a fluorescent probe for environment detection and a preparation method and application thereof.The fluorescent probe has the structural formula shown in the formula (1), is prepared from a compound A and a compound B through synthesis, is stable in optical performance (the probe can be stably stored at the room temperature for six months or above, and the spectral property of the probe is kept unchanged), high in sensitivity and high in copper ion recognition capacity, and can be used for detecting copper ions. During detection, the solution is changed from yellow to red, naked eye recognition can be realized, the selectivity is good, the response speed is relatively high (the response time is 5 minutes), the response range is 0.1-10 [mu] mol.L <-1 >, the detection limit is low (34nM, a method based on 3 times of blank sample standard deviation given by the International Pure and Application Chemical Combination), and the method can be used for detecting copper ions in a water body and
