摘要
针对区域性污水排放量与工业、农业的经济发展及人口增长紧密联系的特征 ,提出了系统多要素影响的区域污水排放量的偏最小二乘回归统计预测模型。所建模型综合考虑了系统要量的影响 ,并且主元的提取在一定程度上克服了变量间的多重共线性影响。经实例检验 ,模型在作中长期预测时精度较好 ,结论可靠 ,并具有一定的物理意义。
Aimed at the contacted characters of regional sewage quality, industrial and agricultural economy development and suburben population increasement, a biased smallest two multiplication method is raised to establish satistical predication model of sewage water output affected by many factors. In the model, main variations abstracted to a certain sense overcome the multiple linear influences of variations. Practice has testified the model is precise in predication and the model has a physical meaning.
