摘    要:
传统的模糊综合评价法用于地表水水质评价,当指标数较多时需要设计很多隶属函数,设计和计算工作量皆很大,实际使用不便。在设定指标参照值和规范变换式基础上,将指标按各级标准规范值相近程度进行适当分类,只需分类设计隶属函数即可,大幅减少了计算工作量,使模糊综合评价法应用于地表水水质评价变得简化。

关 键 词:环境科学  指标规范值  模糊综合评价  参数优化

Abstract:
When a traditional fuzzy synthetic evaluation has numbers of index for surface water quality assessment,many membership functions are necessary to design resulting in inconvenience due to great works of design and calculation.On the basis of setting index reference values and normalizing conversion of indexes,the indexes were classified according to the close extent of their standard normalized values.Furthermore,membership functions were designed only according to classification.In this way the fuzzy synth...
Keywords:Environmental science  normalized values of index  fuzzy synthetic evaluation method  parameter optimization
