The invention provides a method for evaluating the odor degree of an urban and rural black and odorous water body. The method comprises the following steps: step 1, acquiring conventional water quality detection parameters related to the black and odorous water body; 2, establishing correlation analysis, and identifying water quality detection parameters related to an odor threshold value; 3, extracting main control parameters through factor analysis, and obtaining factors as analysis objects of the fuzzy comprehensive evaluation model by combining a correlation analysis result; 4, optimizing the fuzzy comprehensive evaluation model, and then establishing an improved fuzzy comprehensive evaluation model to judge the black and odorous condition of the water body, so as to obtain a fuzzy comprehensive evaluation result B. The method provided by the invention is an independent evaluation method capable of judging the stink of the water body and the stink causing degree, so that the stink degree of the water body
