摘要

By collecting and analyzing sediment samples from 16 river sections of the Daxia River and the main tributaries, the contents of five heavy metals Pb, Cr, Cd, Cu, and As in the sample data were detected, fuzzy comprehensive strategies were used to determine the heavy metals in the river basin,then made an assessment for the pollution situation . The result showed that the order of heavy metal pollution in the soil of Daxiahe River was Cd>As>Cr>Pb>Cu. Among them, the pollution assessment level of 16 river sections is V1, and it belongs to a clean state. The pollution evaluation level of the 6 river sections is V2, which is still in a clean state, and the pollution level of a river section is V3, belonging to a light pollution state.
