目前广泛使用的地下水水化学分类方法为舒卡列夫、布罗茨基或阿廖金分类。在山区和山前区,使用这些方法所编制的水化学图尚不能很好地反映水化学的成因。我们改用Q型群分析进行分类及编图,现介绍如下: 一、方法简述 1.原始数据:因水的矿化度、总硬度等与有关的离子含量有关,呈线性相关关系,故不列入项目中去,每个水 Currently widely used method of classification of groundwater chemical classification of Shu Karev, Brodsky or Alejandin classification. In mountainous and piedmont areas, the water chemistry diagrams prepared using these methods do not adequately reflect the cause of water chemistry. We use Q-type group analysis for classification and coding, are described as follows: First, a brief description of the method 1. The original data: Due to water salinity, total hardness and related ion content, was linearly correlated, so Not included in the project, each water
