| 摘 要： | 利用主成分分析法确定模糊评价法中评价指标的权重,克服了由于只考虑评价指标本身的权重而忽略指标的超标权重而对模糊评价的影响,使利用模糊综合评价进行水质评价更简单、实用,在浑河水质评价分析显示,该方法合理、可行,有一定的参考价值.

| Abstract: | The method of principal component analysis is used to determine the evaluating indicator's weight coefficients of fuzzy assessment,which overcomes the defects caused by only considering evaluating indicator's weight while neglecting its' exceeding weight.It makes the water quality evaluation more simple and practical.The water quality evaluation and analysis on Hunhe show that this method is reasonable and feasible,and has certain reference value. |
