【 摘 要 】
At present, under the background of the river length system, the concern for water quality becomes more and more urgent. For there are many influencing factors of water environment change and it is difficult to describe. This paper proposes a fuzzy random risk rate calculation model for water environment water quality exceeding the standard aiming at the randomness and fuzziness of water environment system. At the same time, information entropy was introduced to solve the calculation. Use an example for calculations, the results show that the rate of the DO pollution is 4.3%, COD is 0.16%, and NH4-N is 0.00% .The model calculation results are as good as observed.
