Abstract:
The variable fuzzy model was used to evaluate the water quality of the Chi’ao Reservoir. According to the characteristics of the reservoir, eight water quality evaluation indexes were selected to construct an index system. The two element theory was applied to determine the index weight and calculate the relative membership degree of the model, thereby providing the water quality evaluation results. The results showed that the water quality in the Chi’ao Reservoir is between classⅠand classⅡ, water utilization is at its good level, and water supply can meet the requirements of users. The variable fuzzy model is feasible and practical in evaluation of reservoir water quality.
