Study On Recycling Economy Development Mode Of Pig Husbandary In Wuhan City

With the large-scale and intensive development of pig industry, China is now the biggest pork producing and consuming country in the world. While pig industry is meeting people's increasing demand for livestock products, the traditional production model of mass production, mass consumption and mass waste has made the contradiction between resource and environment increasingly serious. So the urgent problem to be solved is how to seize the new opportunities of pork production, change the development model of pig industry, solve the pollution problem and realize pig industry's sustainable development. The research on circular economy's development model and its application are of great significance to pig industry with the type of high resource consuming and high pollution discharging. Based on the system structure, the thesis is divided into seven parts.In the first part, the thesis mainly contains the research context, the research significance, the outline, the methods and the shining spot. In the second part, it expounds the current research on pig industry's environment problem at home and abroad. In the third part, it has made a perfect exposition about the connotation, denotation and main development model of pig industry's circular economy. Thus the classification standard of development model of pig industry's circular economy has been generalized, and the main theoretical foundation of this research has been formed. The forth part, which is the important chapter of the thesis and main technical foundation of the research, is mainly trying to construct the approach in developing pig industry's circular economy. The technical route of the research includes four stages: the current situation investigation and analysis of influencing factors about pig industry, cluster analysis and division of circular economy in pig industry, the analysis and construction of the development model of pig industry's circular economy, countermeasures of implementing development model of circular economy in pig industry. In the fifth part, the construction approach is applied to specific cases of developing circular economy in pig industry in Wuhan. It gives a quantitative description of the status quo of the pig industry in Wuhan. Using the SWOT analysis, this part has qualitatively analyzed the strategic advantages, disadvantages, opportunities and threats of developing circular economy in pig industry in Wuhan. The sixth part is the empirical study. Using the cluster analysis, we have categorized Wuhan city into several regions, based on the similarity of the index of agricultural economic production, areas and input, the index of output value and income and the index of population and labor force. Based on actual situation of each region, we put forward corresponding dominant development model of circular economy in pig industry, and analyze the principle, function and benefit of each model. Part seven is the conclusion and future prospects.
