FUZZY ISODATA聚类法在地下水水化学分类中的应用

本文以杜热草场水化学资料为例,运用FUZZY ISODATA聚类方法对地下水水化学类型的划分进行了初步研究,并与传统的舒卡列夫法和基于模糊关系聚类法所得结果进行了对比,说明了本方法的可靠性。文中运用该法对研究区水化学成份划分的五种类型,基本符合本区地下水化学成份形成与分布规律,分类合理,计算简便,特别是对水化学成份差别不大的地区更为适用。

APPLICATION OF THE FUZZY ISODATA METHOD TO THE CHEMICAL CLASSIFICATION OF GROUNDWATER

Taking the hydrochemical data in the Dure grassland as an example, a preliminary study of the chemical classfication of groundwater was conducted by means of the Fuzzy Isodata cluster analyzing method in this paper.As compared with the results obtained by the tranditional Shukaliefu method and with those by means of the Fuzzy relation cluster method, the data show that the new method is reliable. In this paper the new method was used to divide water samples into five hydrochemical classes in the Dure grassland, which basically accord with the formation and distribution of the groundwater composition. The new method proved the results of hydrochemical classification reasonable and the calculating method quite simple. It is more useful particularly in the areas where the difference among the chemical compositions of groundwater is small.
