三江源区生物质资源沼气化利用潜力评价

The evaluation of the renewable resource potentional in the source region of Yangtse river,Yellow river and Lantsang river

分析和评价三江源区生物质能资源潜力,是建设庭院生态经济模式的基础。通过构建模型的方法,对三江源区的养殖业生产和牧区居民生活过程产生的畜禽粪便和人粪尿等生物质能源潜力进行了估算,分析结果表明,仅2011年,江河源区产生的牲畜粪便总量为5 819.31万t,人的粪便总量为135.92万t,合计5 955.23万t,如果进行沼气化利用,可产生沼气11.23-18.84亿m3,相当于7.97-13.38亿kg的标准煤,对三江源生态移民点和灾后恢复重建点发展能源型庭院生态经济模式具有重要作用。

It’s the resource basis of building mode of courtyard economy to analyze and evaluate the biomass energy resource of the three-river fountainhead .The article estimate the biomass energy potential ,such as livestock and poultry manure ,human excreta and so on ,which produced by the breeding production and the pastoral resident life process of the three-river fountainhead ,it shows that just in 2011 ,the total livestock and poultry manure produced by the three-riv-er fountainhead is 5 819 .31 × 104 t ,the total human excreta is 135 .92 × 104 t ,add up to 5 955 .23 × 104 t .If carry on biogas utilization ,it can produce 1 .123 × 108~1 .884 × 108 m3 of biogas ,which is equivalent to a standard of 7 .97 × 108~13 .38 × 108 kg .It plays an important role in ecological settlements and area of post-disaster reconstruction of the three-river fountainhead developing mode of energy courtyard economy .
