Water resources system is a complicated large system, whichrncontains regional background, as well as specific framework, function and dynamic balance. The evaluation of the water resources system needs thernmeasurement according to both water resources carrying capacity and water environment carrying capacity, and the supervision with the viewpointrnof sustainable development. The water resources system of Lake Taihu basin experiences a degenerate period from 1960, and the year of 1980 is arnturning point of the degeneration. Therefore, it demands to use the concept and theory of circular economy and to be based on the water resourcesrnsystem, to improve, harmonize and counterpoise water resources carrying capacity and water environment carrying capacity, to insist the “3Rrnprinciple”, to save water and use water efficiently. Consequently, human can coexist with water harmoniously, and gain sustainable development,rninsuring the sustainable social-economic development with the sustainable use of water resources.
