Research On The Theory And Application Of Harmony Regulation For Human-water Relationship

Water is the most critical resources for human production and living. It is also one of the important material foundations for sustainable economic and social development. There is no doubt that the process of human developing is closely related with water resources. With the rapid development of society and economy, water problem has become a huge obstacle to the further development of human society and the human-water relationship have faced more serious challenge than ever before. Therefore, seeking human-water harmonious development is a key way to solve the above problems, and human-water harmonious development has gradually become the focus of global attention. The idea of human-water harmonious is of very important and has practical significance to formulate and implement regulatory strategies of water resources. Simulating human-water relationship and building harmonious regulation model based on the idea of human-water harmony is an "important" addition to the research system of human-water relationship. Also, it provides an important theoretical basis for the decision making of water resource management. Analyzing research status at home and abroad and existing problems of current researches is the first step to this research, and then the former research results of our research group are introduced to study the theory and application of human-water harmony regulation. In this paper, the research mainly includes the following aspects:(1) Researching on the theory and research framework of the human-water harmony regulation. Based on the expounding the concept and the connotation characteristics of human-water relationship, a research framework regarding human-water harmony regulation was carried out. Harmony evaluation, harmony simulation and harmony regulation for human-water relationship made up the main part of this framework. The interrelationships among the evaluation, simulation and regulation for human-water harmony were expounded clearly and the research system of human-water relationship was formed perfectly.(2) Researching on the evaluation of human-water relationship. Based on the system theory, the concept and connotations of human-water relationship were deeply analyzed. According to the rule of "the goal – guidelines-classification- indicators", an index system of quantitative evaluation for human-water relationship was established. More specifically, the system was including eight subsystems: water resources, water environment, water ecology, social development, economic development, science and technology development, water supply, protection and management. A quantitative method from the harmonious theory was introduced to evaluate the harmonious degree of human-water relationship in different regions of Henan province.(3) Researching on the simulation of human-water relationship. Embedded system dynamic model was employed to simulating human-water system. The concrete steps are: adopting water resources transformation equation and pollutants mass balance equation to express water system, and then coupling those equations to the various water modules from humanistic system, finally forming a dynamic simulation model. In order to realize the dynamic simulation of human-water relationship under different scenarios, the dynamic simulation model which we created above was applied in Henan province to research it as a case study. The ultimate purpose of this simulation is to find out the key factors affecting human-water relationship. The results of the study can lay a good foundation for human-water harmony regulation.(4) Researching on the human-water harmony regulation. A regulatory model framework, including the principle, classification, ideas and other aspects of the regulation, was proposed. The matching degree calculation method was adopted to divide the control regions into different control types and put forward two kinds of harmonious regulation models: one is based on harmony equilibrium, called “Harmony Equilibrium Model(HEM)” and the other is based on “Three Red Lines” of the most strict water resources management system, called “Three Red Lines Model(TRLM)”. HEM is an advanced regulation model which is formed by the latest concept and quantitative method of harmony equilibrium and including the general harmonious balance expression. TRLM is an innovative model which is introduced “Three Red Lines” as the constraints and carried maximum harmony degree of human-water relationship as regulation goal.
