Abstract:

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 subsystem,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 systems in south of the Yangtze River was higher than that in north of the Yangtze River.From the adaptive capacity of the various subsystems,primary cities of Jiangsu province 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.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
