Claim 3:
4. The method for assessing microbial drug resistance multi-level risks of antibiotic residues in water environment according to claim 1, wherein the step S3 further comprises environment persistence assessment: the half-life period t1/2 of the target antibiotics or target antibiotic derivatives is obtained by database querying combined with model prediction, an environment persistence level is divided into 3 grades according to the size of the half-life period t1/2: non persistence is t1/2<60d, persistence is 60d<t1/2<180d, and high persistence is t1/2>180d; when t1/2>60, the target antibiotics or target antibiotic derivatives have environment persistence, so regardless of the drug resistance risk RQr value of the microbial flora in the target watershed, step S4 is carried out for further assessment.
