摘要
以地下水水质指标国家分级标准为训练样本,用样本的地下水水质综合指数计算值作为样本的期望输出值,对BP网络进行训练,用训练好的网络对某地地下水水质监测点进行优选。结果表明:BP网络用于地下水环境监测点优选具有简单、实用和客观性好的特点。
Selecting the national stardards of groundwater as training samples, and using the value of comprehensive index of groundwater quality of each sample as its target value, the training was performed to BP network. The trained network was applied to optimize the groundwater quality monitoring sites of a region. The results of this optimal methods shows that it has simplicity, practicability and objectivity for BP network to optimize groundwater (quality) monitoring sites.
