Research On Scale Breeding Epidemic Prevention For Emergency Management Mechanism Construction And Management

The frequent occurrence of emergency event in the world highlights that the modern society needs the emergency management urgently. Based on the summary of historical experience and the scientific analysis of the public security situation, Chinese government makes a major policy decision of comprehensively strengthen emergency management. The suggestion of "establish and improve the classification management, levels of responsibility, compartmentalized integration of territoriality based emergency management system, the formation of a unified command, responsive, coordinated, orderly and efficient operation of emergency management mechanism" were proposed in the report of the party’s sixteen session of third, fourth, Fifth Plenary Session of Chinese Central Committee. The specific demand of further improving emergency management mechanism has also been put forward in the Seventeenth Party Congress report. Furthermore, the importance of the construction of emergency management mechanism is explicit and stressed repeatedly in the government meetings, reports and related regulations and documents. After2002, affected by factors such as economies of scale, farming conditions and policy-orientation, the proportion of the scale farming enlarged from15%in the late1990s to25%now, a few areas has even reached40%. In2009, the ratio of pig’s production in the scale farms and in small farms was developed to61.3%to38.7%. The rapid development of large-scale breeding industry brought more and faster economic benefits than planting to farming enterprises (farmers). However, the extensive breeding model is always accompanied with widespread outbreaks of livestock disease. The livestock epidemic disease is always variability of seasonal, sudden, repeated occurrence, and epidemics cross. The epidemic spreads to the total area, even invaded the entire world. This situation is not only seriously damaged the economic interests of the farming enterprise (farmers), but also make the public have to worry about the issue of food safety. For any more, it causes the uncertainty of the healthy development of China’s market economy. All of this makes the outbreak of large-scale breeding emergency situation to become increasingly severe. It is an important an urgent issue of how to proceed from reality, to fully draw on emergency management mechanisms, advanced concepts and technologies as well as the related theories and methods at home and abroad, the actual focus of the current large-scale breeding problems, take effective means, prevention and treatment, from the source of disease outbreaks and spread of this important issue before us an urgent situation, to take practical and effective means of prevention and governance and the source of the spread of outbreaks based on The actual focus of the current large-scale breeding situation.Guided by the basic construction and management work of emergency management mechanism, using the emergency management theory, saturated flow theory and hybrid genetic algorithm, Feedback simulation technology of System Dynamics, and the theory of corporate social responsibility, five weak links of the emergency management mechanism is identified in this paper. The study is conducted by the means of a combination of theory and Practice with the case of Jiangxi Yinhe Eucommia green scale breeding region. We have designed a three goals rotation of six storage processes biogas slurry planting network system by the proposed hybrid genetic algorithm, to realize the goal of the zero pollution of anaerobic liquid within the breeding region and solve the problem of the second pollution of anaerobic liquid. We simulate the development of the biomass in bio-liquid with the SD rate variable fundamentals in-tree modeling approach. We characterize and analyze the game behavior of the government, agricultural enterprises and the public in the process of prevention and control of pollution with System dynamics and Evolutionary game analysis approach, and put forward the corresponding policy recommendations.The main conclusions of this dissertation are as follows:1. Study on the innovation direction of large-scale breeding emergency management mechanism.Based on new analysis and definition of the implication and systematic framework constitution of emergency management mechanism, and combined with the current practical condition of emergency management work in china, innovation analysis focused on five critical weak points, such as risk management and insurance mechanism, information management mechanism, information publication and public opinion intervention mechanism, interest appeal mechanism, supervisory evaluation and accountability mechanism, which must be set up and improved urgently during the construction process of emergency management mechanism.2. Design an algorithm to find the minimum flow in the upper and lower bounds network, and give a hybrid genetic algorithm of finding the minimum saturated flow in the network of emergency.In emergency network, the saturated flow is the feasible flow whose flow amount cannot be enhanced any more by only increasing flows along the forward direction, and the minimum saturated flow is the saturated flow with minimal flow amount among all the saturated flows. Minimum saturated flow problem (MSFP) is to find the minimum saturated flow and its corresponding minimal flow amount in emergency network, which is a NP-hard problem. In this paper, MSFP is formulated using a combinatorial optimization model. Based on steady-state genetic algorithm as framework, and minimum flow algorithm as decoder, a hybrid genetic algorithm named MSFP-HGA is proposed as a solution method of the model. Taking advantage of special network structure of MSFP, the MSFP-HGA algorithm has good performance in the sense of being implemented on computer, computational time, required memory for computation, and ability to search global optimum. Numerical experiments demonstrate that the MSFP-HGA algorithm is an efficient and robust method to solve MSFP.3. Design a three goals rotation of six storage network for large-scale biogas slurry treatment process based on the maximum flow and minimum saturated flow mixed Genetic Algorithm, as well as the actual demands.Secondary environmental pollution of scale breeding aroused by the rural biogas projects is the key issue in current rural environmental pollution management, which also contains the agriculture industrialization development and affects the Chinese characteristics agricultural modernization process. A case, which is a six storages network system divided into three layers has been studied on resolving secondary environmental pollution from YHDZ scale breeding ranch with algorithm of Maximum Flow and Minimum Saturated Flow and an efficient method is presented to find the minimum amount of outflow per day for biogas slurry without pollution in scale breeding.4. Present a rate variable fundamental in-tree progressively modeling approach, and with which, we do a Simulation Analysis of Scale Pig Breeding Liquid Biomass Development to demonstrate that the development and utilization of liquid resources conducive to pollution prevention and green food raw material supply.Pig manure is waste biomass resources; it is rich in organics and fertilizer ingredients such as Nitrogen, phosphorus, potassium. Scale pig breeding liquid aquaculture biomass resources are the waste biomasses mainly in pig urine. The manure and urine of pigs breeding in YHDZ are separated, and the manures are processed into organic fertilizer for sale. The development and utilization of the large quantity of liquid waste is an issue to be investigated. We study the issue of Scale Pig Breeding Liquid Biomass Development of YHDZ corp. via simulation analysis. Based on the record and five-year,10-year development plan of YHDZ, by using the rate variable fundamental in-tree progressively modeling approach, we develop a simulation model with seven in-trees.5. Demonstrate Solutions close to the actual situation with the SD evolutionary game analysis framework.Environmental protection is one of the important contents in corporate social responsibility of agricultural enterprises. On the base of the discerning of meaning, characters and problems of agricultural enterprises social responsibility, a main feedback frame model of YHDZ ecosystem environmental pollution has been set up with System Dynamics. In the portrayal of the environmental pollution causes, the root causes of environmental pollution has been found by the definition of stochastic stable state and analysis of policy matrix of environmental pollution control. Policy suggestions have been proposed from the point of agricultural enterprises, government and society in order to help agricultural enterprises to practice their social responsibility.6.
