摘要
运用模糊数学综合评价模式,对珠江口海域近20 a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。
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.
