Water environment quality evaluation based on FMEM

The objective water environment quality evaluation is very important to prevent and control the water pollution and provide scientific basis for water management. This paper is a trial application of the fuzzy matter-element evaluation method (FMEM) as a water environment quality evaluation method. In this method, compound fuzzy matter elements are established first, followed by establishment of the correlation function and evaluation method. The feasibility of this method is verified by citing water environment quality evaluation of DaWen River as an example.
