摘要
在对饮用水系统适应能力界定的基础上,基于水源地、供水系统、用水系统、排污处理系统和社会系统等环节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,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:长江南岸地区饮用水系统适应能力高于江北地区;从各子系统适应能力得分情况来看,需加大省辖市水源地的保护力度,合理规划港口、码头等的布设;加快江北地区供排基础设施的建设;培养经济发达地区的节水意识;提高全区的技术水平。
Based on a detailed discussion about the conception of urban drinking water system adaptation, this study established an drinking water system adaptive capacity assessment index system and model of areas along riverside from the aspects of adaptation factors in water sources sub-system,water supply subsystem, water user sub-system,sewage treatment sub-system and technology sub-system. According to the model, the drinking water system adaptive capacity, including spatial differentiation, types and influencing factors of cities along the Yangtze River in Jiangsu Province was evaluated. The results showed that the adaptive capacity of urban drinking water north of the Yangtze River. From the ada province need to make greater efforts on sys ptiv tems in south of the Yangtze River was higher than that in e capacity of the various subsystems,primary cities of Jiangsu 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. Economically advanced districts should enhance the awareness of water conservation and all the cities need to improve their ability to cope with emergency risk and technology.
