摘要
介绍了水质评价的国内外研究进展,阐述了水质评价的意义,同时系统性地总结了水质评价的方法。分析得出,为确保合理利用水源、保护水源,有必要对水质评价进行系统的研究,模糊综合评价方法可以将不确定的因子定量化,是具有广阔应用前景的水质评价方法,主成分分析法可以较为客观的对评价因子进行赋权。上述分析为水库水质评价提供了理论依据。
This paper introduces the progress of domestic and foreign researches on water quality evaluation, expounds the significance of water quality evaluation, and sums systematically up the methods for water quality evaluation. It can make conclusions that： it is essential to make systematic study on water quality evaluation for guaranteeing the reasonable utilization and protection of water resources, the fuzzy comprehensive evaluation, which can make uncertainty factors quantitative, is a method for water quality evaluation with wide application prospect, and the principal component analysis can objectively determine the weight value of evaluation factors. The above-mentioned research provides theoretical basis for water quality evaluation of reservoir
