中文摘要：
以天津市9个区县作为研究对象，定量分析农村沼气生物质能两大类资源——农作物秸秆和畜禽粪便的状况，根据不同农作物谷草比系数、折算标煤系数以及畜禽粪便综合利用系数，计算出天津市农村生物质能耗占全市新能源消费总量和农村生产、生活能耗比例。同时，详细分析了天津市农村沼气生物质能发展的五大利用模式，并且对全市农村户用沼气工程进行了环境效益分析。结果表明，天津市武清区、宝坻区、蓟县和静海县农作物秸秆资源量在天津市排名分列前4位，宁河县、静海县、武清区和宝坻区畜禽粪便资源占有量分列天津市的前4名，全市农村户用沼气池替代秸秆减排CO2达到1万多t。
英文摘要：
This paper regards nine districts and counties in Tianjin as the research objects,which analyzes two kinds of vital biomass energy resource-crops straw and livestock manure quantitatively, according to different crops RPR and converting to standard coal coefficient, we can calculate the ratio of Tianjin rural biomass energy in new energy consumption amounts and which in rural production and life energy consumption. At the same time, five vital utilization mode of Tianjin rural methane biomass energy and environmental efficiency of all rural domestic biogas projects are analyzed. The results show that Wuqing, Baodi, Jixian, and Jing haixian place to four in crops straw resource rankings, Ninghe, Jian haixian, Wuqing and Baodi place to four in livestock manure rankings respectively, the rural household biogas digesters alternative crops straw CO2 emissions more than ten thousand tons.
