%X Shortage of rural household energy seriously affects eco-environment in the loess hilly region of Gansu province where soil erosion is serious and rural population live a harsh livelihood.Taking the Qizuei village of Tongwei county as a case,this paper estimated the potential of energy resources and actual energy consumption of rural households in the village,and analyzed consumption structure of energy through theoretic modeling and questionnaire survey.Results indicate that there is a higher potential in local energy resources,but their utilization ratio is limited.The potential of bio-fuel resources(fuel grass,straw and animal dung) is 2 364.93tce.The factual consumption is 724.43 tce,accounting for 30.63% of the potential.Solar energy resources that can be exploited by solar stove are 147.1 tce.The factual use 76.54 tce,accounting for 52.03% of the potential.Commercial energy(coal,gas and electricity) that households consume under payment now are 655.88 tce.Each person consumed actually 489.5kgce per year and each family with 4.2 persons consumed 2.061tce per year,which may meet the basic demand of a household.Based on resources attribute,the structure of energy consumption is analyzed as follows:1)Self-producing resources with 54.98% of the total consumption energy couldn't meet demand of households.The commercial energy with 45.02% of the total plays the positive role to the conversion of energy structure,but it increases economic expenditure of household;2)Bio-fuel accounts for 48.79% of the total of energy consumption,coal 38.13% of the total,cleanliness energy only 13.07%.This structure has a serious impact on ecological environment;3)The energy used for cooking and heating accounts for 94.4% of the total.The energy use for lighting and household appliance occupies only 5.6%.This shows that the level of energy use in the study area is low and the structure of energy consumption is reasonless.It is of great significance for ecological protection and building a well-off society through development o solar energy and biogas and restructuring of the rural household energy consumption.
