水质评价理论模式研究进展及趋势分析

水质评价理论模式可以分为确定性与不确定性两大类,其中,以不确定性评价模式最为引人关注。根据各评价方法所依据的理论基础,可将不确定性水质评价模式概括为模糊数学法、灰色系统理论法、数理统计法、物元分析与可拓集合法、人工神经网络法、投影寻踪模型法以及其它方法等类型。文章对每种方法研究现状进行了简要综述,并对水质评价理论模式的发展趋势作了扼要分析。

Progress and trend analysis of theoretical methodology of water quality assessment

The theoretical methodology of water quality assessment can be generally divided into certain models and uncertain models, and the uncertain models are more attractive.The uncertain models of water quality assessment are introduced and analyzed, which are based on the theory of fuzzy sets, the grey system theory, the mathematical statistics method, the matter element and extension method, the artifical neural network method, the projection pursuit method, and some other methods. The development trend of theoretical methodology of water quality assessment is discussed.
