| 摘 要： | 通过分析人工砂石料系统中废水排放、噪声、粉尘等8个因素对环境的影响,建立了基于误差反向传播(BP)神经网络的人工砂石料系统环境影响评价模型.基于模糊数学思想,对影响因素中的定性属性进行了量化;对定量属性进行了归一化.考虑选址的敏感性,并将相关国家标准规定的污染物排放限值归一化,共同组成输入样本对BP网络进行训练.实例分析验证了该方法的可行性.

| Abstract: | The environment impact assessment model based on BP neural network is established for the artificial aggregate system after analyzing eight factors which having impacts on environment,such as waste water,noise and dust.Based on the idea of fuzzy mathematics,the qualitative attribute of the factors are quantified,and the quantitative ones are normalized.The emission limit of each factors determined by national standards on environment protection are input as training samples to BP neural network.The case stu... |
