摘要
科学客观的评价水质,是做好水资源管控的前提。当前应用的水质评价方法存在定性与定量结合不好、评价结果与法定标准不一致、计算过程复杂、评价结果不直观形象等问题,有必要研究更加科学实用的评价方法。参考了单因子评价法、污染指数法和标识指数法等广泛使用的评价方法的优点,并对水质指标浓度实行了去量纲的标准化处理,改进设计出一种水质级别指数法。结果表明:该方法实现了水质定量和连续化分析,可以有效地开展水质指标间对比分析、时间上变化趋势分析和空间上变异情况分析,在桂南沿海地区水质评价、预警和水质月(专)报编报过程中得到了较好应用。该方法简便易行,具有一定推广价值。
Scientific and objective evaluation of water quality is a prerequisite for water resources management.The currently applied water quality evaluation methods have problems such as poor combination of qualitative and quantitative evaluation,inconsistent evaluation results with legal standards,complex calculation processes,and unintuitive evaluation results.It is necessary to develop a more scientific and practical evaluation method.Based on the advantages of the widely used evaluation methods,such as single factor evaluation method,Water Pollution Index(WPI)method and water quality identification index method,the Water Quality Level Index(WLI)method was designed and improved in this article,and the Water Quality constituent concentrations were standardized by de-dimension treatment.The results showed that the WLI method truly realized the quantitative and continuous analysis of water quality.With this method,the water quality index comparison analysis,time change trend analysis and spatial variation analysis can be effectively carried out.The method has been well applied in water quality assessment,early warning and water quality monthly(special)report preparation in coastal areas of southern Guangxi.It was proved that this method is simple and easy to implement,and has certain promotion value.
