通过收集恩施市三龙坝村2000年和2008年能源结构调整的各能源的数据,用能值法转换成能值指标体系,分析各能源在农业生态系统中的作用,再以一家典型户为代表具体分析沼气工程在家庭农业生态系统中的作用.结果显示沼气工程的建设使三龙坝村能源结构发生了较大的变化,促进了新型能源的普及利用,沼气普及率达到61.53%,全村每年热值增产共9.84×1012J.沼气在2008年的总能值比例占总数的10.59%,木柴占10.31%,较2000年减少了11.41个百分点,蜂窝煤也减少了9.43个百分点,液化气减少了0.21个百分点,电和块煤的能值比例较2000年有所增加.对典型户研究可知,沼气工程的建设在家庭农业生态系统中所占的比重较大,由2000年的0%增加为2008年的10.09%,为家庭创造了8355.68×1012sej.a-1的能值.说明三龙坝村通过沼气工程建设,不仅为家庭增加了一种新型清洁能源,而且在家庭农业生态系统中起到了重大的作用.

Through collecting the energy data about energy structure adjustment in Sanlongba village of Enshi in 2000 and 2008,the emergy method is used to convert into indices system to analyze the energy in the function of agricultural ecosystem.A typical household is used to analyze the role of the methame project in the agro-ecosystem.Results showed that methane project greatly changed energy structure of Sanlongba village,promoted the popularization of the new type of energy,and the biogas popularization reached 61.53%.Biogas in 2008 accounted for 10.59% of the total emergy,wood,accounted for 10.31%,reduced by 11.41 percentage points,honeycomb briquet reduced by 9.43%,liquefied gas reduced by 0.21 percentage points the emergy proportion of electricity and coal 2000 increased.The study on the typical household shows that the biogas project accounts for a large proportion in household agricultural ecosystem,increasing from 0% in 2000 to 10.093% in 2008,and created 8355.68×1012sej·a-1 emergy for the family.The study shows that construction of methane project in Sanlongba village has not only increased a new tpye of clean energy,but played an important role in the household agricultural ecosystem.
