A watershed local water quality criteria verification method, which belongs to the field of water quality criteria derivation and verification. The method comprises the following steps: step 1, analyzing watershed biota distribution features; step 2, removing non-native related species from a target contaminant toxicity database; step 3, supplementing toxicity data of local native sensitive organisms and specific species; step 4, constructing a watershed native toxicity database; step 5, comparing the degree of fitting of a species sensitivity distribution (SSD) model and determining the optimal SSD model; and step 6, verifying a water quality criteria value, and completing derivation and verification of watershed local water quality criteria. The method can significantly improve the nativity of watershed local water quality criteria, is used for formulating watershed local water environment quality criteria, and provides important support for watershed water quality management.
