Gansu Province Agricultural Biomass Potential Evaluation Research

Biomass energy has the characteristics of reproducibility and environmental friendliness.At present,energy shortage and serious environmental pollution in China make the effective exploitation and utilization of biomass energy the main content of our country's energy strategy.Gansu Province is an important agricultural and animal husbandry production area in China with abundant biomass energy reserves and natural advantages of exploitation and utilization of biomass energy.The positive development of agricultural biomass energy is of great significance to promote the transformation of rural energy structure in Gansu Province,improve the level of agricultural modernization,improve the living environment in rural areas,and increase farmers' income.The main sources of agricultural biomass energy in Gansu province include crop stalks,animal manure and fuelwood.By collecting the raw material data of agricultural biomass energy from Gansu Rural Yearbook from 2007 to 2016,the comprehensive evaluation of biomass energy from different sources was carried out.Firstly,the energy conversion values of different sources of biomass energy are evaluated by combining the relevant energy collection coefficient,the possible source coefficient,and the standard coal coefficient.Then combined with the space-time distribution and evolution of biomass energy from different sources in Gansu Province to carry out spatio-temporal evaluation and analysis;after that,through the accounting of economic and environmental indicators,the comprehensive benefits of biomass energy from different sources are evaluated.Finally,Different Analysis in Gansu Province based on the above Analysis Evaluation and Analysis of Comprehensive potential of Biomass Energy from sources.On the basis of the above comprehensive evaluation of biomass energy from different sources,the comprehensive potential evaluation of total biomass energy in Gansu Province was carried out according to the development and basic characteristics of Gansu Province.The problems existing in the process of biomass energy development and utilization in Gansu Province and the parts that need to be improved are found out,and corresponding optimization measures and policy suggestions are put forward.According to the above analysis,the relevant conclusion is drawn: 1)in the process of specific utilization,evaluating the energy potential of various kinds of agricultural biomass energy is a prerequisite for rational utilization of biomass energy.2)Agricultural biomass energy potential is usually compared with that of agricultural biomass per capita.The dominant areas of biomass energy potential of straw are Zhangye City and Qingyang City,and the general areas of biomass energy potential of straw include Wuwei City,Jiayuguan City,and Jiayuguan City.Pingliang and Linxia.4)the dominant areas of biomass energy potential of livestock and poultry feces in the province are Zhangye City and Gannan City,which are the more developed areas of animal husbandry in Gansu Province,and the potential areas generally include Linxia City.Pingliang city and Jinchang city.5)the dominant area of biomass energy potential of fruit-wood is mainly distributed in Tianshui city,Pingliang city and Qingyang city.For the key development and utilization area,moderate development and utilization area,limit the development and utilization area.Different utilization regions correspond to different biomass energy utilization modes,which should be adapted to local conditions and develop suitable biomass energy industries.
