江苏省典型中小城市常州市需水量变化规律及论证

Change law and demonstration of water demand in Changzhou City,a typical small and medium sized city in Jiangsu Province

为保证节水规划与需水量的平衡,综合考虑城市特点进行需水量动态分析是十分必要的。基于常州市相关城市建设规划内容,通过对其节水潜力及社会经济指标的分析,明确需水量预测背景条件及定额;分别选用分类与分项用地指标法进行城市需水分析,论证相应节水规划及需水结构的合理性。研究可知,预测结果论证了常州市到近期(2035)、远期(2050)规划年农业及农村生活用水量在逐年减少,工业及城镇生活用水量在逐年增加,与其城市规划建设发展趋势一致。在需水量分析中的各类定额选用,可为江苏省典型中小城市相关规划分析提供参考。

In order to ensure the balance between water saving planning and water demand,it is necessary to make dynamic analysis of water demand with comprehensive consideration of urban characteristics.Based on the relevant urban construction planning content of Changzhou and the analysis of its water saving potential and social and economic indicators,the background conditions and quota of water demand prediction are defined.The classification index method and classification of land use index method are used to analyze the urban water demand,and the rationality of the corresponding water saving planning and water demand structure was demonstrated.According to the research,the forecast results demonstrate that in the near term(2035)and long term(2050)planning years,the agricultural and rural water consumption in Changzhou will decrease year by year,while the industrial and urban water consumption will increase year by year,which is consistent with the development trend of urban planning and construction.The selection of various quotas in the analysis of water demand can provide references for the related planning analysis of typical small and medium sized cities in Jiangsu Province.
