摘要
物元分析是用来处理在某些条件下用通常的方法无法达到预期目标的不相容问题的一种分析方法,本研究在简要阐述物元分析基本理论思想的基础上,应用该方法对盐城自然保护区近海海域水质进行综合评价。结果表明:该海域水质符合GB3097-1997海水水质的二类标准,水域污染类型以氮磷营养盐为主。评价结果既客观地反映了该海域的综合水质现状,又能直观表达各污染指标的贡献权重,计算过程意义明确、条理严密、可复制性强,可在其他环境因素的质量评价理论方法和应用中借鉴和推广。
The matter element analysis theory is the way of deal with some problems which can＇t reach the aim in some special conditions. On the basis of the principle of matter element analysis,The study applyed it to assess water quality of Yaneheng Nature Reserve. The result showed that the water quality conform the II standaid of GB3097 - 1997 seawater quality ,the main pollution type is nitrogen and phosphorus nutrients. The result no only showed the comprehensive water quality objectively ,but also expressed the contribution of pollution indicators intuitively. The method is clear, tight, easily copy, and it can be used widely in other environment assessment.
