Analysis On The Economic Benefit Of Biomass Energy Forest In Different Planting Patterns And The Life Cycle Energy Consumption

Energy shortages and environmental pollution are two major problems that need to be solved in the world.At present,the use of energy is mainly fossil fuels,but fossil fuels are not renewable,and their reserves are gradually reduced.Therefore,it is very necessary to find alternative renewable energy sources.Biomass energy can not only reproduce,have a stable source,but also a large-scale alternative to fossil fuels,to meet future social energy needs,ease the energy crisis,safeguard national energy security has important significance.At present,China’s energy forest focus on the development of Cornus wilsoniana,Sapindus,Xanthoceras sorbifolium Bunge and other species,the main factors restricting the development is the reliable supply and prices,as well as the production of energy consumption.Therefore,this paper focuses on the impact of plantation model on fruit yield,estimates the cost and benefit analysis of three kinds of tree species as bio-energy,discusses the energy consumption of biodiesel production in the whole cycle,and obtains the following results:1.The profitability of different energy forest plantation model is different,the profitability of asexual reproduction is the highest.With the extension of the energy forest construction project cycle,the cumulative increase in raw material sales revenue,the project has a good continuity.2.Different energy forest raw materials profitability is different,profitability of Xanthoceras sorbifolium Bunge is the highest,and its fruit prices are closely related.3.In the asexual reproduction mode,the production capacity of biodiesel is the highest,and FNPV is 74685.68 yuan/mu.The comprehensive utilization of energy tree species,can effectively improve its economic efficiency.4.The cost of producing biodiesel is higher.It is recommended to select high-yielding energy forests and optimize biodiesel conversion technology to increase the profitability of biodiesel production.5.Considering of by-products,the net energy efficiency of biodiesel production is higher,with a net energy efficiency of 4.65.All of the three energy forest production of bio-diesel life cycle process,have a positive energy efficiency,can effectively save fossil energy,bring environmental and social benefits.
