【摘要】 根据东湖多年监测数据分析，建立了多元相关预测模型、基于灰色理论灰色系统的预测模型和质量平衡模型。为了提高灰色预测精度，利用残差对模型进行了相应的修正，并利用３种模型对影响东湖水质主要因子——经济、人口、ＢＯＤ、ＣＯＤ、ＴＮ、ＴＰ进行了２０００年的预测，提出了东湖污染防治对策更多还原

【Abstract】 In this paper,forecasting models,such as multivariate regression model,grey model and mass balance model have been established on the basis of analysis of monitoring data for East Lake,Wuhan City.In order to improve precision,the grey model has been revised by using residual error equation.The population, economy,BOD,COD,TN,TP about 2000 have been forecasted with these models.The proposals of administering for East Lake have been advanced.更多还原
