摘要
以我国家养动物和动物废弃物甲烷排放量现状估算值为基础,根据我国人均肉类需求量和人口总量的变化计算我国肉类总需求量(1990-2020年),分高、中、低三个方案用IPCC推荐的计算方法和文献1提供的计算系数对各年度我国家养动物(牛)甲烷排放量进行预测。预测结果表明:2020年我国家养动物(牛)的甲烷排放量高方案为14.54Tg/a;中方案为7.998Tg/a;低方案为6.096Tg/a。
ased on the presently estimated amount of CH_4 emitted from domesticanimals and their wastes,the present requirement for meats and the incr-ease of the requirement for meats from l990 to 2020,the amount of CH_4emitted from domestic animals every year was forecasted using the compu-tation methods recommended by IPCC and the calculation coefficient givenin reference l with low,middle and high level.The calculation results sh-owed that the amount of CH_4 emitted from domestic animals was 6.096 Tg7.998 Tg and l4.54 Tg for low middle and high levels,respectively,in theyear of 2020.
