摘    要:运用模糊数学综合评价模式,对珠江口海域近20a水质进行综合评价分类.结果表明,水质多年变化总的趋势是不断恶化,主要污染物质已由重金属污染过渡到营养盐污染;与单项分指数法比较,认为模糊数学综合评价模式更为合理和全面.

关 键 词:珠江口  模糊数学  水质评价  模糊数学  珠江口海域  水质  综合评价  Estuary  fuzzy  mathematics  water  quality  比较  指数法  单项  营养盐污染  金属污染  物质  趋势  多年变化  结果  分类  评价模式  运用

Abstract:The assessment of the water quality in Zhujiang Estuary was made by the fuzzy mathematics for last 20 years. The results show that the water quality in Zhujiang Estuary has been deteriorated during the period, The main pollutants were changed from the heavy metals to nutrients. Comparing the method of single sub-index, the assessment method of the fuzzy mathematics is available and reliable.
Keywords:Zhujiang Estuary  fuzzy mathematics  water quality assessment
