Abstract: Biomass energy is in urgent current need and it is going to play an important role in future energy system. The employment of biomass energy reduces the need for fossil fuels and is more environmental friendly. A biomass energy resource survey, evaluation program and technical line were developed in Jiangsu province. The combining method of the census of resource method, the household energy consumption sample survey and the main biomass resources special investigation were put forward. The resource survey and farmers sampling survey scheme were set. The biomass energy resource evaluation, supply and demand balance analysis, resource prediction, key and methods of biomass resource utilization analysis were proposed. This paper provides the methods for provincial biomass energy resource investigation and evaluation.
