两种水质现状评价方法在港口环境影响评价中的应用

根据对水质的监测结果和取水口附近底栖动物的调查结果,分析南通港两个通用散货泊位工程建设对下游狼山水厂取水口水质的影响。用综合生物指数法对取水口附近水域水质评价的结果显示:狼山水厂取水口的综合水质评价等级为轻污,与水质理化指标的评价结果相吻合。综合生物指数评价法与水质理化指标评价法的结果相互印证,这两种水质现状评价方法可在港口环境影响评价中应用,并互为补充。

Application of two water quality evaluation methods in port environmental impact assessment

On the basis of monitoring results of water quality and benthos,the impacts of two generic bulk berths construction in Nantong Port on downstream water quality of water intake were analyzed.The results of biologic assessment show that water quality of the water intake are light pulluted,the physical and chemical indicators of water quality evaluation results are coincide.Composite index evaluation of biological and physical-chemical indicators of water quality evaluation results confirm each other,both water quality evaluation methods can be applied in the port environmental impact assessment,and they also complement each other.
