Abstract: The shortage of water resources has badly influenced the development of city and the basic life of residents, and it will become the important factor to obstruct the economy and the sustainable development of society. Dalian is a city, which very short of water resources. The fresh water is innate scarce, and the distribution of water resources is asymmetric. In this paper, the characteristics of Multi-water resources in Dalian are analyzed. At the same time, from the point of view of systems analysis, the theory of water resources reasonable allocation has been discussed and researched, and an urban multi-water resources system allocation model has been built. The multi-water resources (ground water, surface water, rain water, diverting water from external region, reuse water, seawater and so on) reasonable allocation among multi-user (household, industry, agriculture, ecology environment and so on) may achieve the superior water for the more efficient users, and the inferior water for inefficiency users, thus the utilization efficiency of water resources will be improved. The urban Multi- water resources reasonable allocation is very important for alleviating the urban water scarcity, achieving the sustainable development of urban water resources, and improving the water environment in Dalian city.
