| 摘 要： | 地表水是人们生活及生产用水的重要来源,准确评价水质关系着人们的用水安全。选择集对分析方法和模糊综合评价法评价水质,对比分析评价结果。集对分析法首先用联系度来描述评价因子实测值与地表水环境质量标准的同异反程度,然后通过加和平均求出评价因子对应各级标准的平均联系度,确定水质级别。与模糊综合评价法相比,集对分析方法具有概念明确、计算简便和实用的特点,可以较好地应用于水质评价,为水资源的合理开发利用与管理提供依据。

Surface Water Quality Assessment Based on Set Pair Analysis |
| |
| Abstract: | The quality assessment of surface water, which is the major source of domestic and drinking water in China, is ＇also a part of water security. The set pair analysis menthod as well as a commonly used fuzzy comprehensive evaluation method were applied to assess the same surface water environment. Using the establised set pair model, the individual cooelation coefficients ot field data and the national standard of different grades were obtained, and the grade of water quality was determined by the maximal average correlation coefficient. Comparing with the results of fuzzy comprehensive method, the set pair method reveals its advantages in accuracy, simplicity, which can he put into more practical use in water quality assessment. |
