摘要
可以从定性、定量两个角度解决问题的物元可拓法已被广泛应用于各个领域,本文对物元可拓法进行了改进,并应用于地下水水质评价,同时采用模糊综合评判方法进行了验证.Piper-三线图显示,研究区地下水主要为HCO3-Na和HCO3-Ca·Na型水,水质本底条件较好.水质评价结果表明,上第三系馆陶组地下水水质显著优于明化镇组,1984～1999年间明化镇组和馆陶组的地下水水质均有变坏趋势,前者趋势较为明显.物元可拓法采用综合关联度与可拓指数判断地下水水质级别,不仅能反映其相对性,也能反映绝对性,可延拓连续的特点使其更有说服力.
Being able to solve problems qualitatively and quantitatively, Matter-Element and Extension has widely been used in many fields. It was improved in this paper, and was attempted to be used in groundwater quality evaluation. The results were testified by Fuzzy Synthetic Assessment at the same time. Groundwater there in the study area was mainly of HCO3-Na and HCO3-Ca· Na types on the Piper diagram, and the background of groundwater quality was found good. The results of evaluation indicate that the groundwater quality of in the aquifers of the Guantao Group was evidently better than that in aquifers of the Minghuazhen Group of the Upper Tertiary Series. The groundwater quality of the aquifers of the Minghuazhen Group and the Guantao Group was getting worse from 1984 to 1999, and the trend of the former was even more obvious. Using Integrated Relating Rate and Extension Index to estimate the level of the groundwater quality, the Matterelement and Extension can reflect not only the relativity but also the absoluteness, and the characteristics of extended continuum brought it more persuasion.
