Abstract

Water environment system is a large complicated system, there are some uncertainties in assessing water quality, yet fuzzy mathematics is the mathematical method which processes and researchs the fuzzy phenomenon. Based on the theory of fuzzy mathematics and the standard limited value of the appraisal factor, a membership function expression was established, and a computation based on the actual measured data thereafter. The result shows that the water quality of Qinghe Reservoir watershed is poor and Reservoir entrance, Hong Huadian, Tie Jiagou, Zeng Jiatun and YaoPu are belong to standard, which matches the practical situation of water quality.

模糊数学在清河水库水质评价中的应用研究
水环境系统是一个庞大的复杂系统,水质评价存在一定的不确定性,而模糊数学是处理和研究这种模糊现象的数学方法。基于模糊数学理论和评价因子的标准限定值,建立了隶属函数表达式,并根据实测数据进行了计算。结果表明:清河水库流域水质较差,水库入口、洪华店、铁家沟、曾家屯和姚铺水质达标,符合实际水质情况。
