Chinese Rural Household Biogas Utilization Analysis Based on the Regional Risk Assessment

摘要

as one of the important means to solve rural energy and environmental problem, construction of rural household biogas is of great significance to promoting rural sustainable development and socialist new countryside construction. In USA, Greece, Sweden and some developing countries, it is extensively researched and widely applied to use straw as biogas fermentation material to produce biomass energy, which plays a positive role in accelerating resource utilization. With constantly improving of straw-to-biogas production technology system and development of new countryside activities, making full use of straw resources will become an inevitable tendency of Chinese biogas development. However, because of the wide geographical distribution of China rural area and great difference between areas, there are differences in the development status of each area. Therefore, based on regional risk assessment, the papers is going to build a regional risk index system of biogas, evaluate risk of rural household biogas in each area of China, carry out empirical analysis of related data in China from 2005 to 2015, and propose policy recommendations, from reginal risk factors of household biogas in the four aspects of raw material supply, system and technology level, temperature guarantee and socio-economic conditions.
