地质体内元素含量与水体质量的关系分析

An Analysis on the Relationship between Element Contents in Geological Body and Quality of Water Body

为分析地质体内元素超标与水体质量的关系，收集了18组统计数据，采用线性回归的数学方法进行分析，得出影响水体质量的元素包括：有机物、无机物、有毒物质和金属元素，并建立了通过以上元素预测水体质量的预测模型，该模型预计结果较为可靠，精度较高。

In order to analyse the relationship between standard-incompliant elements in geological body and quality of water body, 18 sets of statistical data were collected. By using mathematical methods of linear regression analysis, elements affecting the quality of water body were found to include organic, inorganic and toxic substances and metallic elements. A water quality prediction model through those elements has been established. It was indicated that the model would be reliable with higher precision.
