Abstract: A pattern of multi-source water supply including surface water,groundwater,reclaimed water,water from the Yellow River and the Yangtze River has been formed in Shandong Province. But many enterprises compete for local low-cost surface water,groundwater and water from the Yellow River,rather than high-cost water from the Yangtze River. In order to effectively absorb the high-cost water from the Yangtze River and promote water use efficiency,it is necessary to establish a comprehensive water price model of multi-source and multilink water supply system based on the refined optimal allocation of water quantity,water quality and water price. According to the actual situation of water resources development and utilization in Zouping City,this paper calculates and analyzes the comprehensive water price of the multi-source and multi-link water supply system for industrial water. This is of great significance for the scientific and effective management of the existing water supply system,the realization of water supply at the same price of external water transfer and local water,the guidance of water use behavior of water users,the protection of regional water supply safety and the sustainable and healthy development of economy and society.
