| Energy is the fundamental material guarantee for the development of social economy,among them, biogas is a renewable clean energy. Today, countries around the world have stepped up efforts to develop and use of biogas energy. In our country, after a long period of exploration and a series of practice, the development and application of the technology in the development and application of the biogas pool has gained great achievements, the level of technology and the degree of penetration are all in the world. The key to solve the problem of "agriculture, countryside and farmers" and to build a new socialist countryside is to popularize the use of biogas energy in the rural areas. Zaozhuang City, Shandong province has a relatively good development of rural biogas energy conditions, the current number of Zaozhuang owned by the country’s first gas pool. Rural area of Zaozhuang City make full use of biogas energy, not only effectively adjust the original structure of fuel in rural Zaozhuang City, promote the process of the fuel in rural areas, and ensure the stable development of rural areas and greatly improve the living standards of farmers and so on in all play an indispensable role. Obviously, further analysis of Zaozhuang City, construction of biogas digesters in rural areas to the people in the rural area of Zaozhuang City, helps to expand the biogas energy use in the popularity of rural area, so as to further accelerate the pace of construction of rural economy.This paper based on literature analysis method and empirical research method, in Shandong Province, Zaozhuang City rural households using biogas construction as the research object, combing the Shandong Province Zaozhuang City rural households with current situation of Biogas Construction Based on household biogas construction of economic benefit, social benefit, ecological benefit and benefit of energy substitution empirical evaluation, and puts forward, Zaozhuang City, Shandong Province households using biogas construction optimization suggestions, realize the significance of theoretical analysis and practical significance. First of all, the introduction part of this paper are summarized on the Shandong city of Zaozhuang Province Rural Household Biogas research background and significance, the construction of the domestic and foreign research status, research contents and research methods of this paper; secondly, the relevant theoretical basis of the constructionof biogas by combing, a comprehensive overview of the agriculture sustainable development theory and ecological economic system emergy analysis theory renewable energy theory,which lays the theoretical foundation for this study; third, analysis of Shandong city of Zaozhuang province rural household biogas construction situation, basic energy status in Zaozhuang city farmers survey and overview of Zaozhuang city of Zaozhuang City, the rural household biogas situation, at the same time in Zaozhuang, household biogas construction design factors the index system and the empirical model, the empirical analysis; fourth, the construction of economic benefit and social benefit evaluation of biogas households in Zaozhuang City,. For the strong city of Zaozhuang rural household biogas construction financial benefit and economic benefit at the same time, Zaozhuang city rural household biogas construction is benefit to enhance rural environmental awareness, adjusting rural energy structure, optimize the industrial structure of agriculture, improving the quality of life of farmers; fifth, through the empirical analysis of Zaozhuang rural household biogas construction, ecological benefit index system determine the index weight, and that Zaozhuang rural household biogas construction plays an important role in the two aspects of environmental benefits and environmental health; sixth, proposed the Shandong city of Zaozhuang province household biogas construction optimization suggestions that Zaozhuang city household biogas construction in order to improve the rate of households biogas suitable areas, improve the technical personnel of biogas construction team, enhanced technology the level of biogas construction, establish and perfect the construction of biogas service system,promote the construction of Biogas Ecological environmental benefits, expand biogas In the end, the research conclusion and Prospect of this paper are put forward. |
