| 摘 要： | 讨论土壤主要温室体ＣＯ２，ＣＨ４和Ｎ２Ｏ的排放过程，计算我国农田生态系统排放ＣＯ２、ＣＨ４和Ｎ２Ｏ的总量。１９９０年，中国地区ＣＯ２、ＣＨ４和Ｎ２Ｏ农田排放源强分别是２６０ＴｇＣＯ２，１７．５ＴｇＣｈ４和０．０９６ＴｇＮ，它们占我国相应这些气体排放量的８％，５０％和１０％，论述了温室气体浓度增加可能以农业产生的影响及应采取的控制对策。

| Abstract: | The emissions processes of greenhouse gases such as CO2,CH4 and N2O from agricultural soils have been studied in this paper.The source strengths of the gases emission from agricultural activities are calculated as 260 Tg of CO2,17.5 Tg of CH4,and 0.096 Tg of N,which accound for about 8%,50%,and 10% of their total emissions in China.An effect of moresing the concentration of these greenhouse gases in atmosphere on agricultural production are also discussed.Some of control strategies on the gases emission from soils,are suggested. |
