摘要
工业用水影响因素众多。为了定量辨识影响因素与工业用水定额之间的关系,在分析工业需水影响因素的基础上,建立了以主成分分析法——定额法组成的工业需水预测模型,并以郑州市为例进行了分析检验,结果表明,郑州市在未来2010年、2020年和2030年工业需水量分别达到46818×104m3、48441×104m3和47517×104m3,工业需水定额分别为41 m3/104元、19 m3/104元和12 m3/104元,工业需水量及需水定额比较符合郑州市的发展实际,该模型是可行的。
Industrial water demand is affected by many factors. In order to research quantitative re- lationship between influencing factors and industrial water quota, a forecast model used of Principal Component Analysis-quota method is established based on analysis of industrial water demand factors. The Zhengzhou City is taken as an example for the analysis. The results show that the indus-trial water demand in the future of 2010, 2020 and 2030 will be reached 46818× 10^4 m^3, 48441×10^4 m^3, and 47517×10^4 m^3 respectively, and the industrial water quota was 41,19, and 12 m^3 per ten thousand Yuan. This results also show that the industrial water quota and demand are conformity with the development practice of Zhengzhou, and the model is feasible.
