利用线性回归偏离角评价地下水质量

Evaluation of groundwater quality by using linear regression deviation angle

介绍了线性回归偏离角的基本概念及其在地下水质量评价中的应用,并与内梅罗指数法、模糊综合评判法、物元可拓法及BP神经网络模型法评价结果对比,证明利用线性回归偏离角评价法判定地下水质量等级结果客观、准确、合理。

The basic concept and its application of linear regression deviation angle are introduced in the evaluation of groundwater quality. The comparisons of the evaluated results with those from Nemero index, fuzzy comprehensive method, matter-element analysis and BP neural network model show that the method of linear regression deviation angle which is applied to the evaluation of groundwater quality is objective, accurate and reasonable for the evaluation results.
