| Pig production is in the dominant position in the livestock industry, with an irreplaceable significance for the development of social economy and improvement of the living standards of the people, also an important "three rural" issue. With the development of pig industry in China and the continuous development of pig production scale and industrialization degree enhances unceasingly, manure production scale of pig farming increased dramatically and relatively centralized, which can not be consumed by surrounding land, pig manure transited from organic fertilizer resources into pollution sources, environmental pollution problems have become increasingly prominent; and biogas as an important household biomass resources, households biogas project promotion and construction is a national strategy, in which the problem of shortage of raw materials and technical services lack existing. Basing on the existing research results, this dissertation, in view of the scale pig farming waste pollution problems and biogas, biogas slurry development lack, explores the effective model of cable in pig breeding waste treatment and biomass resources development. In this dissertation, the research work and main results are as follows:1. Through analysis of the basic situation of the pig production of consumption in China in recent years, the Chinese pig production and consumption in China animal husbandry and production and consumption of pork in the world occupy a dominant position. Based on the analysis of "company+pig farmers" model’s system dynamic mechanism and the game of elimination mechanism, the reasons Scatter-feed without market development and risk response ability continuously leave in recent years, the conclusions show:with the development of social economy and the progress of production technology, the pig industry in China is on the track of scale rapid developmentally, the pig industry of our country is toward the large-scale aquaculture development, large-scale pig farming has become a major breeding mode of China’s pig industry.2. Using DEA to carry out the evaluation of breeding efficiency between the different pig scale, compared to the backyard, small and medium scale shows a certain technical efficiency and scale efficiency, breeding technology and management capacity upgrade in large-scale pig farming has played a more prominent role. Establish the evaluation index system of the bearing capacity of the scale pig farming environment, through factor analysis and AHP method, evaluates the environment bearing capacity of2000-2011scale pig breeding, which warns environment capacity of live pig breeding is declining, relationships between the natural environment must be properly dealt with on the development of scale breeding.3. Through the SD archetype for the scale pig farming system and the household biomass resources system analysis and the fundamental mode operating, puts forward to the cooperation development mode between live pig breeding and biogas resources.Doing system analysis using system dynamics on the live pig breeding and biogas question and operating on the scale pig farming and household biomass resources mode, constructs the development cooperation innovation mode of scale pig breeding and biogas, the system dynamics model of the research shows that the pig breeding and biogas development cooperation can relieve the scale pig breeding pollution, improve farmer’s production efficiency, increase farmers’ income, and realize an important strategic goal of livelihood projects and the biogas project to improve the quality of life of the rural areas. Scale pig farming as an inevitable choice of pig breeding, with the expansion of the scale of pig farms and increasing the size of farms, environmental pollution problems of scale pig farming have become increasingly prominent. Development cooperation mode of scale pig breeding and biomass resources with the restriction on scale pig breeding pollution and biogas energy shortage and service technology, which is an effective mode to the scale pig farming waste treatment and recycling of resources development.4. Combing the model of evolutionary game theory and system dynamics to establish SD evolutionary game model to analyse the dynamic evolution of the scale pig breeding and household biomass resources development system, which achieves effective combination of system dynamics and evolutionary game model and dynamic simulation of the related factors of the evolutionary game of steady state and policy, which innovate the complex system analysis methods and tools connected effectively by the game theory and system dynamic, further enrich and perfect the system dynamics theory.Through a combination of farmer behavior theory and game theory and evolutionary game theory, on the basis of extensive researches, analyze and discusses living pig breeding and the evolution of farmers’ behavior in biomass resources development cooperation system. The evolution game theory is the evolution dynamically process of the study behaviors, and system dynamics is precisely the dynamic process of complex system, through the combing of system dynamics and the game theory and evolutionary game theory, combines effectively of dynamic replication system dynamics and evolutionary game theory, establishes the SD model of evolutionary game theory, evaluating dynamically based on system dynamics among the farmer, the scale pig farming enterprise, government three a subject in the live pig breeding and biogas development system behavior, concludes policy suggestions to promoting the farmers, the scale pig farming enterprises and government to participate in the live pig breeding and biomass resources development cooperation system.5. The concepts of archetype generating set core, archetype core were further proposed; and the scale pig breeding and biomass resources development system structure was analysed using archetype generating set core and archetype core, which perfect archetype generating set theory, and make the process of analysis of system structure more concisely.From the view of system, the rate fundamental in-tree model on SD about characterization of the scale pig farming and household biomass resources development system operating mode was established, using strongly simplified rate variable based in-tree of SD to get minimal archetype core by doing embedding operation and get archetype generating set core from the minimal archetype cores and specific archetype cores and doing inverse transformation of the transformation from rate variable based in-tree of SD to strongly simplified rate variable based in-tree of SD and get generate archetypes of scale pig breeding and biomass resources development system; and using archetype generating set core to generate archetypes, combining with the method of determinant feedback loop computation to systematically analyze scale pig breeding and biomass resources development system, which obtained that the method using strongly simplified rate variable based in-tree of SD to get minimal archetype core by doing embedding operation and get archetype generating set core from the minimal archetype cores and specific archetype cores and doing inverse transformation of the transformation from rate variable based in-tree of SD to strongly simplified rate variable based in-tree of SD is more succinct was obtained, which provide an more succinct method to do archetype feedback analysis of a complex system. At the same time, using the core of archetype generating set to generate archetypes and determinant analysis was born in pig breeding and biomass resources development cooperation system with the restriction from the pollution of the environment, farmers from restricting energy use feedback archetypes ring algorithm feedback, land problem becomes the main factor restricting the model.6. Using the Jiangxi Debang pig breeding and biomass resources development system as a case study, after system structure feedback analysis on the live pig breeding and biogas development, build the SD model of evolution game to analyze the stability of Debang pig breeding and biomass resources development cooperation model system and countermeasures the simulation, concluded policy recommendations to promote live pig breeding and biomass resources development cooperation. |
