基于图表及统计方法的水化学综合分析

Comprehensive Analysis of the Hydrochemistry based on Graphical and Statistical Methods

某拟建工程位于四川乐山市红层地区。根据工程建设前水文地质勘查中获取的水化学资料,结合当地自然地理特征、地质及水文地质调查资料,应用图表和聚类分析方法,分析了该研究区水化学基本特征及形成因素。同时对比了两种水化学分析方法。分析结果认为,研究区水化学特征具有相似性,但不同地形及地质条件控制下的水化学特征又具有一定差别;在水化学特征较为相似的地区,统计分析结果比图表分析结果具有更强的可读性。

A proposed project is located in the red bed region of Leshan of Sichuan Province.According to the hydrochemistry data from hydrogeological investigation,the paper combines with geographic features,geological and hydrogeological survey,applies graphical and statistical methods,analyses the hydrochemistry of this region and its forming factors,at the same time,compares the two analyze methods.The analyzed results indicated that tthe hydrochemistry characteristics of the project area are similar,but there are some slightly difference for the geographic and geologic conditions.Finally the results of statistical analysis are more readability than graphical in the area which the hydrochemistry characteristics are relatively similar.
