江苏省沿江城市饮用水系统适应能力评估

Adaptive Capacity Assessment of Drinking Water System: The Case of Citys along the Yangtze River in Jiangsu Province

在对饮用水系统适应能力界定的基础上,基于水源地、供水、用水、排污处理和技术5个子系统的适应性要素构建沿江城市饮用水系统适应能力评价指标体系和评价模型,采用分指数与综合指数法评估系统的适应能力水平、存在问题,并据此对江苏省沿江地区城市饮用水系统适应能力分异特征、类型及影响因素进行深入探讨。结果表明,南部环太湖地区城市饮用水系统适应能力高于中部滨江地区,北部地区适应能力最低;从各子系统适应能力得分情况来看,需加大对沿江地区水源地的保护力度,合理规划港口、码头等的布设;加快北部地区供排基础设施的建设,提高风险应急防范能力;南部环湖地区重点开展节水型企业与生态工业园区创建。

Based on a detailed discussion about the conception of urban drinking water system adaptation,the essay establishes an adaptive capacity assessment index system and model of drinking water system in areas along riverside from the aspects of adaptation factors in water sources,water supply system,water user system,sewage treatment system and social system.According to the model and the method of sub-index and integrated-index,the drinking water system adaptive capacity,including spatial differentiation,types and influencing factors of cities along the Yangtze River in Jiangsu Province is evaluated.The results showed that：the adaptive capacity of urban drinking water systems in the areas around Taihu Lake is higher than the primary cities along the Yangtze River,the drinking water system adaptive capacity of the secondary cities in north of the Yangtze River are minimum.From the adaptive capacity of the various subsystems,primary cities along the Yangtze River need to make greater efforts on the drinking water source protection and rational planning of the layout of ports and terminals.The cities in north of the Yangtze River should speed up its infrastructure construction on supply and discharge.Southern cities in south of Yangtze River should enhance the awareness of water conservation and the secondary cities in north of the Yangtze River need to improve their ability to cope with emergency risk.
