Abstract


Agriculture is the foundation of our national economy, the establishment of modern agriculture demonstration area is an important measure to speed up the industrialization process of China's western mountain agriculture; overall revitalization of the effective ways to accelerate our the western mountains economy, social. However, China's western mountains of modern agriculture demonstration zones also exist in the operation and management of the role and function of understanding the nature of modern agriculture demonstration area, not unified, widespread focus on the construction of various types of modern agricultural demonstration park, and despise the operation and management of the phenomenon, the lack of demonstration area a clear purpose, operation and management personnel uneven quality, lack of technical personnel and other issues. Based on existing research results to the East River Area has significant characteristic of the western mountain as an object of study, emergy and material flow analysis theory, on the East River Area during the ecosystems around the modern livestock industry demonstration park planning changes in analysis, trying to build the theoretical basis of modern agriculture park planning and draw the overall evaluation of the planning and construction of the park, thus providing valuable suggestions and opinions for the next step construction of park improvements. Meanwhile, combine the planning scheme for the construction and development of modern agriculture park of the western mountains provide practical recommendations and opinions, and to ensure that reasonable and scientific agricultural park planning and construction. First, the combination of the actual situation of the East River Area, the East River and the modern livestock industry demonstration zone planning, put forward the the Park general idea and Development positioning, planning a park industry constitute the industrial layout, the relationship between the scale of the development of the park industry park industry . The experience of building a modern agricultural parks, including the characteristics of the \Second, the use of emergy analysis theory, comparative analysis of the Donghe modern livestock industry demonstration zone planning and building before and after the value of ecosystem can change, come to the park can the value of the overall evaluation. Park is completed, the total energy input and total energy value of output has significantly increased, the net energy yield ratio, emergy also a significant improvement in the rate of investment and the amount of per capita energy value, the degree of development of the natural resources and economic development The constant increase efforts but in the construction of further improvements still need to pay attention to the protection of the natural environment, resources, alleviate the pressure on the environment. Third, the use of material flow analysis theory and comparative analysis, planning and construction of the modern livestock industry demonstration zone in the East River ecosystem before and after the change of the material flow, come to the park's overall assessment of the material flow. Park is completed, whether it is the total amount of material input or total material output has a relatively large increase in the average utilization rate of fertilizer has increased significantly, and a more balanced use of NPK and other nutrients and reasonable organic fertilizer further increase the proportion of input, more scientific and rational use of human and animal feces, material recycling is more efficient, thus contributing to a virtuous circle of ecological ecosystems, and improve the efficiency of ecological agriculture, and promote the steady improvement of productivity. But the in improved construction next step, still need further optimization of the local industrial structure, improve the proportion of the fruit industry both farming farm ancillary industries, while increasing material input of farmland and woodland. Fourth, the overall evaluation of the Donghe modern livestock industry demonstration park with recommendations for improvement, build a scientific theoretical foundation for the future of the western mountains park planning and construction of modern agriculture, value and material flow analysis theory, combined with specific East River Modern Animal Husbandry Industry Demonstration Park planning program, asked the opinion of the planning and construction of scientific and reasonable.
