摘要
[Objective] The aim was to estimate the total quantity of biomass energy and analyze its environmental benefit in Shandong Province.[Method] Based on the data from the statistics yearbook of Shandong Province in 2010,the total quantity of biomass resources and biomass energy in Shandong Province in 2009 was estimated,and its environmental benefit was analyzed.[Result] Biomass resources in Shandong Province mainly refer to crop residues,forest residues,grassland changed from degraded land.If degraded land became grassland,the total quantity of biomass resources and biomass energy in Shandong Province in 2009 was 182.808 8 million tons and 2.68×1015 kJ respectively.Meanwhile,the reduction of total emission of CO2,SO2 and nitrogen oxides was up to 241.265 million tons,and the reduced emission of SO2 accounted for 48.9% of annual SO2 emission in Shandong in 2009.Planting energy crops plays important roles in the development of new energy sources,reduction of greenhouse gas emission and environmental protection.[Conclusion] The study could provide theoretical foundations for the establishment of energy policy and study on development strategy of biomass energy in Shandong Province.
