China is a geological disaster-prone country. Human production and living, activities such as engineering, makes the frequency and harm of geological disasters are increasingly aggravate trend. The construction of the Three Gorges dam which lead to the great changes in water level, maybe induce a large number of geological disasters, and endanger the safety of the people’s life safety and waterways. In order to solve this serious situation, Chinese government around the goal which reduce the rate of water caused by geological disasters, and the greatest degree to prevent or reduce possible geological disasters,for the geological disaster in three gorges reservoir area focuses on a large scale management, and achieved good results. In this paper, the research methods including comparative analysis, system analysis, combining qualitative analysis with quantitative analysis and so on.The element composition of the three gorges reservoir geologic hazard prevention and control system are settled, analyzes its operating mechanism and the mechanization, and points out the change about the system operation mechanism in next phase.The paper consists of eight parts with the specific contents as follows:Chapter one introduces the propose, research purpose, significance and aim of the topic. It also elaborates the existing problems of the research status at home and abroad.Chapter two analyzes operating mechanism construction of geological disaster prevention and control system for theoretical basis. it defines the concepts of disaster, disaster reduction, and disaster management. In-depth analysis of the characteristics of geological disasters in the three gorges reservoir, the main types and development of geological disasters.It establishes a theoretical framework of the operation mechanism of geological hazards prevention and control system, and points out the main elements of the three gorges reservoir geologic hazard prevention and control system. And analyzes its basic running mechanism. Chapter three, from the macroscopic point of view, for China and the United States, Japan, the two countries which compar the disaster management mechanism, In order to put things in perspective, the current problems in disaster management mechanism in China and makes analysis and exploration. Compared with the United States, Japan’s disaster management mechanism, disaster management in our country remains to be improved in the system, imperfect law related to disasters, and was not well prepared before a disaster prevention and disaster preparedness, early construction of disaster prevention facilities, lack of maintenance, information feedback mechanism should be further improved, construction of investment needs to be normalized.At the same time, based on the analysis of level and position clear geological disaster management belongs to, for later through the three gorges reservoir area analysis of geological disaster prevention and control of large-scale geological disasters prevention and control system operating mechanism in our country is in what stage of a solid theoretical foundation, and also provides theoretical basis for the final summary and discussion.Chapter four, the geological disasters in the Three Gorges Reservoir management has achieved economic and social benefits are analyzed and summarized, and points out the three gorges reservoir area prevention and control of geological hazards, reasons of existing problems, necessity of constructing and operating mechanism. The analysis of the economic benefits of the three gorges reservoir, mainly including economic benefit evaluation research and control economic results; According to the practical engineering of three gorges reservoir area the impact of social production and living, the three gorges reservoir geologic hazard prevention and control work of social benefits, mainly reflected in reducing casualties and political comprehensive benefit, environment comprehensive benefits, and promote local economic development.The management of geological disasters in Three Gorges Reservoir economic benefit and social benefit has been a huge success. It not only serves as a large regional geological disaster management model, and in geological disaster management standardized, scientific and stylized, for other regional geological hazard controlling engineering, and geological hazards involved a large civil engineering has important reference value and application value.Chapter five, chapter six and chapter seven is the main part of the paper. The Three Gorges reservoir geologic hazard prevention and control system is a typical technology systems, with a relatively complete input subsystem, operation subsystem and output subsystem.Chapter five detailed analysis and summed up the three gorges reservoir geologic hazard prevention and control system operating mechanism input subsystem of construction and operation, Including early key project governance, the Three Gorges Reservoir area of three gorges reservoir area prevention and control of geological hazards early scientific research, the three gorges reservoir geologic hazard prevention decision-making organization and division of the three elements around Three Gorges Reservoir area of geological disasters prevention planning as the core, their function and role, to share the function of input subsystem. Chapter six detailed analysis of the Three Gorges Reservoir area are summarized geological disaster prevention and control system operating mechanism operation subsystem of construction and operation,and focuses on move for geological disaster prevention engineering and avoid engineering involved in related issues. Geological disaster prevention project of Three Gorges and the Three Gorges Reservoir geologic hazard removal avoidance engineering constitutes the operation subsystem.Chapter seven, a detailed analysis and sums up the Three Gorges Reservoir geologic hazard prevention and control system operating mechanism output subsystem, construction and operation. The Three Gorges Reservoir geologic hazard monitoring and early warning system and the Three Gorges Reservoir geologic hazard prevention and control of major scientific research jointly constitute the output subsystem. These elements together through certain way between organizations, and play an important role. Output subsystem in the geological disaster monitoring and early warning subsystem and major scientific research of these two elements, for Three Gorges Reservoir geologic hazard prevention and control of operating mechanism construction is particularly important. Geological disaster monitoring and early warning, taking data in the geological disaster prevention and control of running system and feedback function, which is a major export the output, the output information two dimensions have response speed and accuracy, and for the ageing response of geological hazards prevention and control is not only necessary, but also directly affect the whole system running effect. Major scientific research activities, the research is to achieve the purpose of prevention and control system of normalized management. In large-scale emergency management work, after the completion of work center of gravity from the governance known hidden trouble to the prevention and control of new landslide disasters and ongoing governance left hidden trouble change.Chapter eight, the main conclusions and research prospects. Operating mechanism for overall description of the system, further defined in this paper, the main conclusion, innovation points and research direction in the future. This article innovation mainly reflects in two aspects:firstly, it is to use management science, system theory and other theories and methods, discusses the three gorges reservoir geologic hazard prevention and control system operating mechanism, the mechanism of building the three gorges reservoir geologic hazard prevention engineering system input, operation and output of the operation mechanism of three subsystems; secondly, it is the prevention for disasters in the three gorges reservoir geological engineering problems and the results of typical cases comprehensive carding, analysis the development trend of geological disaster management, for our country in the rest of the large-scale geological disaster prevention and control work experience enlightenment. At the same time, because of the Three Gorges Reservoir geologic hazard prevention and control work in phases complete period, the study of its management system, operation mechanism and grooming itself is an innovative work. In addition, the system theory, this paper for the first time, operation mechanism and so on theory is introduced into the three gorges reservoir area of geological disaster management, based on the analysis of the next stage the emphasis of the work, put forward some suggestions.
