Abstract
Reasonable water quality assessment of reservoirs plays an important part in strengthening water source management. Based on the monitoring data on the water quality in Suya Lake Reservoir provided by water quality environmental monitoring agencies, this paper selected typical water quality indexes such as dissolved oxygen, permanganate (CODMn), ammonia nitrogen (NH3-N), total phosphorus (TP) and total nitrogen (TN) as the water quality assessment factors, and applied the fuzzy comprehensive evaluation method to assess the quality of water in the Suya Lake Reservoir on the basis of single factor assessment. The result shows that the fuzzy comprehensive evaluation method can accurately quantify the fuzzy assessment of water quality. The main pollution factors in Suya Lake Reservoir are TP and TN, and pollution mainly occurs in the waters on the west bank of the reservoir (between the Cold Water River and the Lianjiang River), with the Huangxi River and its inlet being the most seriously polluted. This study provides some reference for the improvement to the water quality assessment model and scientific basis for the prevention and control of water environment pollution in the reservoir area.
