基于改进BP神经网络的地下水水质评价——以新疆和田地区为例

Application of BP network to groundwater quality evaluation——Case study of Hotan sub-project area Xinjiang

在阐述人工神经网络基本原理的基础上,提出了地下水水质评价的BP网络模型。并分别利用BP网络模型与传统的模糊综合评判法对新疆和田地区地下水水质进行了评价,结果表明,BP网络模型不仅计算简便,而且具有较高的计算精度。

Based on the explanation of rationale of artificial neural network,the BP Network model for groundwater quality evaluation is established.Then the model and the traditional fuzzy synthetic appraisal method are used to evaluate the groundwater quality in Hotan Prefecture of Xinjiang Autonomous Region.The case study shows that the model possesses the advantage of high accuracy and good practicability and adaptability.
