垃圾填埋场是温室气体产生的一个重要来源，有资料表明美国的填埋场温室气体排放占了所有温室气体排放总量的40％－50％，笔者分析计算了填埋场的温室气体产量，气体产生的主要垃圾成分；提出了减少温室气体排的几个途径，并指出今后的研究方向。

Landfill site is one of the most important sources of greenhouse gas emissions. The available information shows that greenhouse gas emissions from the landfill sites are 40% 50% of the total greenhouse gas emissions in America. The greenhouse gas output is computed in the text and the conclusion that the main components of yielding gas are food and paper is made. Some measures of cutting greenhouse gas yielding are suggested. At last it points out that some research about these measures should be made in the future in China.
