江苏省生活废水排放量的多元非线性回归预测

本文依据1999～2009年江苏省的人均日生活用水量和人均GDP并结合生活废水排放量的资料,建立了生活废水排放量的三维非线性预测模型,并进行了评估和分析,该模型有较高的拟合精度.根据预测数据,2020年江苏省城市生活废水排放量将达66.85亿吨,为2009年排放量的两倍有余,城市生态环境面临巨大压力.最后本文提出了相对应的政策建议,以供相关部门参考借鉴

Prediction of Domestic Waste Water Missions in Jiangsu Province Based on the Nonlinear Prediction Model

This paper established a three-dimensional non-linear prediction model on domestic waste water discharge according to the per capita GDP,per capita domestic water consumption and the data of domestic wastewater discharge from 1999 to 2009 in Jiangsu Province.And the analysis proves the model has a high fitting precision.Based on the prediction data,the amount of domestic wastewater discharge of Jiangsu Province will reach 6.685 billion tons in 2020,more than two times the discharge in 2009,which imposes enormous pressure on urban environment.At last,some policy recommendations were offered as references to the relevant departments.
