摘　　要：已有的基于人工神经网络对大气环境质量预测的研究大多只考虑空间特性,因此,无法准确刻画大气环境中污染物浓度随时间的动态变化规律,更不能实现影响污染物浓度诸因子在时间维上的有效预测。鉴于此,主要在时间、空间上对多聚合过程神经元网络模型进行多次训练与学习,并将训练好的模型对宁东能源化工基地大气环境中污染物SO2的浓度进行预测。仿真实验表明:多聚合过程神经元网络对于大气环境中SO2浓度具有较好的预测能力。In recent years, artificial neural network have been only proposed for solving spatial case of the prediction of atmospheric pollutant concentration, which could not been accurately depicted dynamic change regulation of the atmospheric pollutant concentration in time-varying, So it was not desirable to forecast pollutant concentration in temporal. The purpose of this paper is to present multiple poly- merization process neural network model, which based on temporal and spatial scale. By training and learning repeatedly, the trained network model is derived. Then the model is used to forecast SO2 concentration of atmospheric environment in Ningdong Energy and Chemical Base. Simulation results of SO2 concentration demonstrate that the multi -aggregation process neural network is applicability and effectiveness to predict the concentration of the atmospheric environment.
