Simulating Empirical Study And Theory Construction Of "Yi" On Water Resources System

Relaying on the origin research subject, in the previous research, this article, according to analysis on the related existing achievements on the water resources, the water resources system, the water resources transfers, allocation, protection and management, etc. and background material on Tao river diversion project, took the theory of "Yi" of water resources system integrated with others as the theoretical cornerstone of water resources system regulation and management after a long period of research process. In addition, the new theory was deduced. Empirical study is based on the theoretical one, and mutually fed back with each other. The SD simulating empirical study on diversion & use management of water resources of the study area was based on the present situation analysis of one.In the theoretical study aspect, based on the eight theories such as the "Yi" philosophic thought, dualistic water cycle model, the entropy and the dissipative structure, the sustainable development, the life cycle management, the ecological economy and the circular economy, the environment risk management, the Eco-hydraulic Engineering Construction and the river health maintenance, the "Yi" theory of water resources system was constructed after system integration and organic combination. After the basic principle thought of the theory, it was showed that the water resources system was nested between the system of the human economic society and the artificial environment coupling and the natural ecological environment outside the ecology economic system, and was fluid, open, of temporal processes and periodic cycle complex system, it conforms to the movement principle of the "Yi" theory of the water resources system in the four-dimensional temporal condition. From the angle of the life cycle analysis, the use value of the water resources was of periodicity. In one cycle of water resources use, its use value was different along with the artificial utilization degree. After deduction on the "Yi" theory of water resources system, the water resources could be divided into the fresh water resources, the process water resources, the unconventional water resources, the virtual water resources. The first three were taken as the entity water; the latter was done as the virtual water. In addition, the water resources system was of mutual restriction & the unity of opposites, mutual intertwining & coupling connection, mutual transformation & circular regeneration, inter-coordination & harmonious Symbiosis.In the empirical study aspect, after analysis on the situation of water resources diversion & use in the area studied, the water resources and development & utilization situation for it were showed, and the preliminary program of distribution of water resources of Tao river diversion project according to the different areas and departments. After the analysis on the study area, Anding district was taken as the typical one of simulating empirical study. Based on the "Yi" theory of water resources, the SD models of water resources of Anding were built from the two aspects, independent and related, of the balance between Profit & loss and the regulation of water environment risk. After simulating, the results of it were showed that the change of the balance between Profit & loss and the degree of the regulation, for the balance, of water environment risk. At last, based on the results of the theory study and the empirical one, the total frame and fundamental ideas of water resources system regulation and management were constructed, and some management strategies for the two important aspects of the water resources utilization of circular economy and environment improvement and risk prevention & controlling of the water resources system, and then, the GIS framework of water resources system management was designed preliminarily. Thus, the study on water resources system management was of practical significance and application value.In short, the throughout of "Yi" was taken as the center of this study, the water resources system of the typical area was simulated and analyzed by the SD method. Then it was showed that the development tendency of the water resources system of the study area, and the regulation management strategies and measures of water resources were provided in order to ensure healthy, stable and sustainable operation of the system. Besides, the GIS foundation framework of water resources system management was designed so as to provide the technical support for the accomplishment of the Modern, dynamic, real-time, fine, quantitative water resources management. Besides, the "Yi" theory of water resources founded could provide the new idea and angle for the related study on the water resources system at home and abroad, and the outcomes could provide the important scientific references and technical supports so that the relationship, among the drawing water, transferring, using and discharging in the area, would be of dynamic equilibrium, sustainable coordination, orderly fairness, and the water resources management in the area would be of security & stability, sustainable & health after the finish and operation of Tao river diversion project.
