The Construction Of Ecological Agriculture Circular Economy And Its Benefits From The "Grass-livestock- Biogas-vegetable" Model

Nowadays, the development of agriculture in China is at key phase of transformation and upgrading. The construction of ecological agriculture circular economy is the inevitable requirement of our country. How to increase farmers’ incomes and living standards have become our challenge in the process of ecological agriculture circular economy construction. Ecological agriculture circular economy mainly advocates a rapid development in the economy at low cost and consist important content of sustainable agroculture, which become a hot spot in ecology and agriculture research. Liancheng village located in Taimu Shan city of Fujian province, where possess rich natural resources, and the concept of circular economy was well applied in practice, a example of circular agriculture model is summarized as the "grass-livestock biogas vegetable", on the basis of faming practices, and theoretical premise of circular economy as well as economy profits were analyzed in this paper. The main results are listed as follows:(1) In year 2011 and 2012, considerable economic and ecological benefits were obtained by running the agricultural cycle model of the "grass-livestock-biogas-vegetable". Through the selection of materials, mainly analyzes the benefit of cow pasture link analysis, benefit analysis, benefit analysis, a comprehensive analysis of vegetables biogas benefit analysis and economic benefit obtained comprehensive maize and alfalfa planting, in years of 2012 and 2011, a total of forage planting 94.4 ha, the total output value 2949900 yuan, total profit of 1067300 yuan; the total output value of dairy cattle breeding 15773000 yuan, after deducting the cost of raising spending of 7175500 yuan, total profit of 8597500 yuan; vegetable planting 114.6 ha of vegetables, production more than 19466 tons, the output value 12931100 yuan, profit of 3691500 yuan. In year 2011 and 2012 biogas production economic benefits were 107500 yuan and 100900 yuan. In year 2011 and 2012 "grass livestock biogas vegetable" circular agriculture mode input and economic benefit analysis of the total investment 9466800 yuan, the total output value of 31995200 yuan, total profit of 22528300 yuan.(2)" Grass-Herd-Biogas-Vegetables" circular agricultural planting and breeding pattern development, to comprehensive utilization of agricultural resources, improve the utilization rate of resources, not only can promote the development of rural economy, solve the pollution problem of the farming produce, improve the rural ecological environment, showing good economic and ecological benefits, at the same time, the development " Grass-Herd-Biogas-Vegetables" circulation agriculture can promote farmers to increase farmers’ income, employment promote the new rural construction and improve the enthusiasm of farmers to participate in the development of circular agriculture has a good role in promoting.(3)Based on the above results, we put forward 4 opinion on how to develop circular economy ecological agriculture in farming practice. First, reguard ecological agriculture planning as a guideline, comprehensively promote dairy production and set up some good practice samples in this field. Second, enlarging the scale of circular economy ecological agriculture, thus enhance industrial development level. Third, change the mode of economy growth, to achieve industrial transformation and upgrading.. Fourth, building agricultural service system, supporting the development of circular agriculture ecological economy.
