基于多种方法的淮河流域驻马店段水质综合评价

Comprehensive Evaluation of Water Quality in the Zhumadian Section of the Huaihe River Basin Based on Multiple Methods

为了解驻马店市淮河流域重要支流的水质现状,选取市内5个国控断面,分别使用单因子评价法、综合水质标识指数法及模糊综合评价法分析得出各断面的综合水质类别,并对比三种方法的评价结果。结果表明,综合水质标识指数法评价结果直观合理,计算方法简单,更适合该地区断面的水质评价工作。

To understand the current water quality status of important tributaries in Zhumadian City’s Huaihe River Basin,five national control sections within the city are selected.The single-factor evaluation method,comprehensive water quality index method,and fuzzy comprehensive evaluation method are respectively employed to analyze the comprehensive water quality categories of each section.A comparison of the evaluation results of the three methods reveals that the comprehensive water quality index method provided intuitive and reasonable results,with a simple calculation method,making it more suitable for water quality evaluation work in this region.
