水环境质量模糊综合评价中的一些问题探讨
- FUZZY COMPREHENSIVE EVALUATION FOR WATER QUALITY
- 摘要：水环境质量评价,对于正确了解水环境现状,合理利用与开发水环境资源,科学预测未来水环境变化趋势具有重要意义.建立在模糊集合论基础上的模糊综合评价法是评价水环境质量的一种新方法.与常规评价方法相比,模糊综合评价方法有其突出的优点,因此,日益受到环境评价工作者的重视.国内已有工作发表.我们就水环境质量评价的特点与模糊综合评价方法中的一些问题进行探讨.
- Abstract：The fuzziness of classification for water quality by pollution indices, the statistical fluctuation of measured data of pollution and comprehensive evaluation of multiple parameters were discussed. For defining the classification standard of water quality, the difference of the standard values between two neighbor classes should be larger than confident interval of measured data at given significant level. The effect of the statistical fluctuation of measured data on the calculation of membership degree was evaluated and some formulas for calculating membership degree were recommended.
