Based on lack of hydrological and water quality data, incomplete information in many rivers, the unascertained mathematics is used to calculate river water environmental capacity. This model can provide not only the interval value of river water environmental capacity and its corresponding confidence level, but also the certain value under unascertained information. It presents more useful and scientific information for water pollution prevention. This case study shows that it is feasible, simple, reliable and of good popularization value.
