Evaluation Of Regional Biomass Potential

Energy is an important material for human survival and development,and related to the national economy and national security.As fossil fuels become increasingly drying up,ecological environment worsening,renewable energy has become a fundamental orientation in the transformation of global energy and core content.In many renewable energy,fuel ethanol is believed to be the ideal choice of alternative oil,which can be blended with gasoline in any proportion into ethanol gasoline.It can improve product performance and quality,reduce the pollutant emissions.Development of fuel ethanol industry in China is relatively slow.The biggest bottleneck in fuel ethanol is non-grain materials supply problems.In view of this,this study under the natural suitable-restrictive Society(household survey)-production potential framework of the basic train of thought.SuiXi county,which in the Leizhou peninsula,as the research area,it plant growth condition is good and rich land resources.Using the niche fitness model to evaluate regional natural production potential of fuel ethanol non-grain materials.Based on farmers planting willingness investigation of energy crops,analysis simulation of farmers,government and energy companies to party in the market.Using method of mathematical expectation to simulate the different scenarios of farmers intend to establish biomass under different situation of the research framework of the evaluation of the potential to grow.The main results of this study are as follows:(1)The suitability of cassava planting in SuiXi county is higher,and the main factors affecting its natural suitability are the terrain and soil factors.SuiXi cassava planting suitability of spatial differences,which highly appropriate and moderate suitable land mainly distributed in SuiXi County East,west sides and central city on the ChengYue town and low suitable land mainly concentrated in the central part of the SuiXi.The natural productive potential of 4.1722 million t cassava in SuiXi,Highly appropriate and moderate,low suitable production respectively is 1.6506 million t,1.6172 million t,904400 t.(2)The empirical study shows that the main factors influencing the SuiXi cassava farmers planting wishes are: the peasant household age of the cultivated land,cultivated land and the distance of the road,and irrigation and drainage condition of cultivated land,market factors,expert guidance and help of enterprises,the government's promotion of fuel ethanol eight variables,such as the age of the farmer's expert guidance is a negative impact,and cultivated land and the distance of the road,the irrigation and drainage condition of cultivated land are the main three factors.(3)In different scenarios,the yield of cassava had a higher correlation with government incentives,the government to implement incentive behavior of greater efforts and farmers' willingness to grow higher and higher,the maximum yield can reach 92.7% of the natural production potential.Under the same incentive cost,the output of cassava is higher than that of cassava when the incentive to the enterprise is higher than that of the farmer.According to the different planting scenarios,Combining SuiXi fuel ethanol industry development plan,and puts forward SuiXi middle-east-west in cassava crop sequence development suggestions.
