【摘要】 以查干湖监测数据为例,对其进行模糊综合评价.分别利用主成分分析法、污染超标赋权法和层次分析法确定权重,并对不同赋权方法得出的权重值与评价等级进行比较分析.结果表明,主成分赋权法对权重值的确定能如实反映每一个评价因子在整个环境中的重要性;污染超标赋权法对污染较重的因子赋予较高的权重;层次分析赋权法受主观影响较大.更多还原

【Abstract】 By taking monitoring data of Chagan Lake as an example,fuzzy synthetic assessment was conducted using the principal component weighting,exceeding standard weighting,and analytic hierarchy process.Results show that the principal component weighting can truly reflect the values of various factors;exceeding standard weighting gaves heavier weights to the polluting factors;and the weight values are influenced by subjectivity in analytic hierarchy process.更多还原
