Emergy Theory And Substance Flow Analysis Theory To The Modern Agricultural Park Of Applied Research

Agriculture is the basis of our national economy, the establishment of a modern agriculture demonstration district is the important measure to speed up the mountain west of agricultural industrialization, also is the effective way to accelerate economy in China's western mountainous area and revitalize the whole society.But the modern agriculture demonstration in a mountainous region of western area of our country have existed some questions.For instance, the knowing to role and function in the management of modern agriculture demonstration properties is not unified, the phenomenon about despising management and paying attention to construction is widespread in the modern agriculture parks,the construction of demonstration zone lacks the clear purpose,the quality of management personnel is uneven, it is short of technical personnel.The paper which is on the basis of the existing research results, which is To the donghe area which has significantly mountain west characteristics as the research object, using emergy theory and substance flow analysis theory, through the comparative study about the ecological system of changes before and after In DongHe area with modern animal husbandry industry demonstration park planning, will try to build up theoretical basis regard to construction of modern agricultural zones, draw that evaluation of the overall planning and construction,provide precious advice and opinions for the construction of the park improvements next step.Meanwhile, it combined with the actual this project planning scheme will offer practical advice and opinion for the construction and development of modern agricultural zones in mountain west,and ensures the planning and construction of agricultural zone be the rationality and scientific.First,it combined with actual situation of donghe area plans the modern animal husbandry industry demonstration zone on the DongHe area.The planning includes putting forward the overall thinking and development orientation of the agriculture park, figuring out Industrial structure and industrial layout, the scale of industrial development and each industry's relationship of the zone. Consequently it is able to draw the experience of the construction of modern agricultural zones from practice planning project angle,such as "three-properties and one-characteristics of high" of agriculture parks,"six requirements" of park construction and "Three integration three promote" role. The second, it using the emergy analysis theory, through the comparative study about the ecological system of emergy changes before and after in DongHe area with modern animal husbandry industry demonstration park planning,has studied out the overall evaluation in this park.As follow:After the completion of the park,it will increase about Total cmergy of the input and output markedly.improve in EYR,EIR and EPP significantly, increase the development degree of natural resources and economic development level continuously.But in the improvement of the construction next step, it still needs to pay attention to these aspects including protecting the natural and environment resources mitigating environmental pressure.The third, it using material flow analysis theory, through the comparative study about the ecological system of substance flow changes before and after In DongHe area with modern animal husbandry industry demonstration park planning, has studied out the overall evaluation in this park.As follow:After the completion of the park,it will increase bigger whether total material input or total material output, improve the rate averaged of fertilizer utilization significantly, balance with reasonable about the use of nutrient elements as N,P,K.further improve the investment proportion of organic fertilizers.be more scientific and reasonable the use of Human and livestock manure, be more efficient in material circulation.So it could promote benign circulation of ecological state system. enhance ecological agriculture efficiency.facilitate the productivity improved steadily.But in the improvement of the construction next step, it will still need to further improve the industrial structure,raise the ratio of horticulture and planting industry which is supporting animal husbandry, increase the material input in farmland and woodland.Finally, based on the evaluation of the overall and improvement suggestions for modern animal husbandry industry demonstration park in DongHe area, it will build up the scientific theoretical basis for future planning and construction of modern agricultural zones in mountainous west:the emergy theory and substance flow analysis theory. Meanwhile, in combination with the specific planning scheme of modern livestock industrydemonstration garden in DongHe area,it will put forward scientific and reasonable opinion of planning and construction to the future of modem agricultural zones.
