| The paper is focused mainly to study on the rural energy sustainable development mode with rural biogas as a key point, putting forward the ecological agricultural mode concept of"pig-biogas-fruit"to suit for the development of rural domestic biogas digesters in the rural areas. After many years of practice, local demonstration and integrated evaluation, the mode concept has played a role on perfecting the agricultural allocation, proper use of rural resources and promotion of rural economic development. Modern biogas utilization is integrated totally together with clean production, resource comprehensive utilization, ecological design and sustainable consumption.By the multi-ring feedback-type recycling of"resource-production-product-consumption-wastes resource", it can get the material exchange and energy flow of economic chain, biological chain and ecological chain to operate well so as to utilize and protect resources effectively, become an effective carrier of solving rural ecology, rural energy, agricultural environmental protection and farmers'incoming increase and promote the rural overall, coordinative and sustainable development.The paper has two parts. The first part is the preface, which mainly introduces the development history and background of the Sichuan rural domestic biogas digesters and the study methodology of the paper. The second part is the theoretical basis of the sustainable development of the Sichuan rural domestic biogas digesters, which mainly introduces the related concepts and analysis of basis. The third part is the current status analysis of the development of the Sichuan rural domestic biogas digesters, which mainly introduces the basic features, investment of different years, the existing problems and reasons of the Sichuan rural domestic biogas digesters development. The fourth part is the benefit analysis of the Sichuan rural domestic biogas sustainable development, which mainly indicates the economic benefit, social benefit and ecological benefit of the building cost comparison analysis. The fifth part is the ecological mode of the Sichuan rural domestic biogas sustainable development, which mainly introduces the ecological agricultural mode of"pig-biogas-fruit, analyzes the mode structure features, the building standards and successful examples. The sixth part is the countermeasures of the Sichuan rural domestic biogas sustainable development, which concretely puts forward a few measures of raising up leaders'knowledge , perfecting management system, service system setup, building finance raising and specification of the marketing products.The seventh part is the conclusion, which mainly introduces the current selections faced by the world agriculture and indicates the inevitability of the developing the ecological agriculture in China for the extensively development of biogas ecological agriculture and set up the socialist rural new visage. |
