| 摘 要： | 通过土壤有机质的矿化２作用，模拟估算温度气体在中国土壤中的释放量，结果表明，ＣＯ２从土壤中的释放量为３７．５亿ｔ／ａＣＨ４从稻田中的释放量为０．２０亿ｔ／ａ，Ｎ２Ｏ从稻田中的释放量为３．４５万ｔ／ａ，对土壤中温室气体释放估算提供了一种简便方法，由于掌握资料不足，准确估算需进一步研究。

| Abstract: | Greenhouse gases emission from soils in China was assessed based on the mineralization rate of soil organic matter. It was estimated that 3. 75 billion tones of CO2 from soils and 20 million tones of methane and 34500 tones of N2O from paddy soils in China were emitted into atmosphere every year. The assessment provides a simple method for assessing greenhouse gases emission from soils. Because of the limitation of data available further studies should be taken for more reliable estimation. |
