中文摘要	喀斯特山区生态环境脆弱,能源利用模式低值粗放,开展该区域的农业可利用生物质能潜力研究,对喀斯特山区农村能源建设和生态环境保护具有重要意义。以贵州省为例,在考虑土壤生态保留前提下,利用草谷比、土壤生态保留系数、收集系数、折标系数、副产物系数估算农村地区可利用农业生物质能资源总量。结果表明: (1) 20092015年间,贵州省年均可利用生物质能资源量达5191.5010~4 t标准煤,地均和人均农业生物质能资源量分别达到295 t标准煤/km~2和1.48 t标准煤/人,其中年均可能源化利用的达到1974.0510~4 t标准煤,占贵州省同期能源消费总量的21.84%。(2)贵州省生物质能储量结构比例分布不均,畜禽粪便资源利用潜力巨大,贡献值高达85%;其中,牛粪资源蕴藏量达年均3009.78*10~4 t标准煤,贡献值达到68.39%,是贵州省最重要的农业生物质能资源。(3)从时序变化特征看,20092015年间贵州省生物质能资源量呈现U形结构,2011年达到最低值,这与2010年的西南大旱重要事件耦合。最后,针对贵州省农业生物质能现状,论文提出喀斯特山区应该合理布局秸秆电厂和秸秆固化成型燃料生产企业,提高畜禽的规模化养殖水平并加强农业生产防灾减灾工作,农村生活能源推广以沼气、节柴灶与节能秸秆气化炉高效利用相结合的能源利用结构等建议。
英文摘要	The fragile eco-environment,together with low efficiency energy utilization,are typical features of the socialecological system in Karst mountain areas. It is of great value to determine the potential agricultural biomass resources (ABR) for rural energy construction,and ecological environmental protection of these areas. Based on a case study of Guizhou Province,considering the returning ecological straw biomass for soil and water conservation,this paper estimated the total available ABR in rural areas using the residue to product ratio,ecological returning coefficient,collection coefficient,conversion coefficient to standard energy,and process residue factor. The results showed that: (1) from 2009 to 2015,the ABR of Guizhou Province increased to 5191.50 * 10~4 tce annually,with a density of 295 tce /km~2 and 1.48 tce / person,respectively. About 1974.05 * 10~4 tce of energy-oriented biomass resources are available annually,accounting for 21.85% of the total energy consumption during the same period in Guizhou; (2) the proportion of biomass energy reserves in Guizhou Province is unevenly distributed. The potential utilization of livestock and poultry waste is considerable,with a contribution value up to 85%; the average amount of cattle feces biomass is up to 3009.78*10~4 tce annually,with a 68.39% contribution to the total animal excrement,which is the most important ABR in Guizhou Province; (3) a U-shaped temporal characteristic change in ABR occurred during 2009 to 2015 in Guizhou Province,with the lowest level in 2011, which showed a coupling with an important ecological event of the southwest drought disaster in 2010. Finally,based on the current agricultural biomass resources in Guizhou Province,this paper suggests that the straw power plants and straw curing for fuel factories should be distributed evenly in the karst mountain area,improving the current scale of livestock breeding, strengthening agricultural disaster prevention,and popularizing the comprehensive utilization of biogas,efficient firewood stoves,and energy saving straw gases in karst rocky desertification areas.
