Abstract

Water quality index (WQI) is one of the most used tools to describe water quality. It is based on physical, chemical, and biological factors that are combined into a single value that ranges from 0 to 100 and involves 4 processes: (1) parameter selection, (2) transformation of the raw data into common scale, (3) providing weights and (4) aggregation of sub-index values. The background of WQI is presented in this review study. the stages of development, the progression of the field of study, the various WQIs, the benefits and drawbacks of each approach, and the most recent attempts at WQI studies. In order to grow and elaborate the index in several ways, WQIs should be linked to scientific breakthroughs (example: ecologically). Consequently, a sophisticated WQI that takes into account statistical methods, interactions between parameters, and scientific and technological improvement should be created in order to be used in future investigations.

水质指数研究的历史、模式、尝试与展望

水质指数(WQI)是最常用的描述水质的工具之一。它是基于物理、化学和生物因素组合成一个单一的值，范围从0到100，涉及4个过程:(1)参数选择，(2)将原始数据转换为公共尺度，(3)提供权重，(4)子指标值汇总。本文综述了WQI的研究背景。发展阶段，研究领域的进展，各种WQI，每种方法的优缺点，以及WQI研究的最新尝试。为了以多种方式发展和完善该指数，应该将wqi与科学突破(例如:生态学)联系起来。因此，为了在未来的调查中使用，应该创建一个考虑到统计方法、参数之间的相互作用和科学技术改进的复杂的WQI。
