Abstract :
With the tourism exploitation of World Natural Heritage Wulingyuan, its water environmental quality emerges a marked downward trend. We take BOD5, COD, TN, TP, As and MnO4- as evaluation factors, which have important influence on water environmental quality. Then we use fuzzy comprehensive evaluation method, gray correlation analysis method and TOPSIS evaluation method to respectively evaluate Wulingyuan water environmental quality. By comparison we find that fuzzy comprehensive evaluation method is able to truly reflect the status of Wulingyuan water environmental quality. According to these, some corresponding measures are put forward to provide scientific basis for improving the ecosystem environmental quality of Wulingyuan and its surrounding areas.
