摘要
地下水污染是当前较为严峻的现实问题,地下水水质评价是开发和保护地下水资源的前提,将BP神经网络应用到地下水水质评价中,解决了以往评价方法人为性较大和隶属函数构建不合理等问题。应用实例表明,BP神经网络法训练速度快、精度高,能如实地评价地下水质情况。
Now, the pollution of groundwater has become the serious and practical problems, groundwater quality evaluation is the precondition of exploitation and protection groundwater resource. BP neural network is used in groundwater quality evaluation by this paper, it resolved some the former evaluation＇ s problem which was thought as has mere man - made property and belonging function construction is unreasonable. It is illustrated that this method of BP neural networks has excellence as rapid speed and high precision, and it could evaluate the instance of groundwater quality.
