| 摘 要： | 多角度认识农田生态系统在CO_2源或汇的问题有助于中国制定正确的农业管理措施,通过减少农田生态系统碳的排放或增加碳的储存,可以使中国在国际排放权的争夺中处于主动地位;笔者总结了国内外最新文献中农田CO_2交换量的研究现状和通量观测方法;对近年来国内外农田生态系统CO_2交换量研究所取得的进展进行了详细阐述,并介绍了测量农田生态系统CO_2通量的微气象法和箱法等通量观测的代表性方法,列表说明了涡度相关法、静态透明箱法、静态暗箱法三者存在的优缺点。分析了提高农田生态系统碳交换测定通量的准确性的途径及扩大不同农作物CO_2测定量的适用范围;对农田生态系统CO_2交换量观测全面深入研究提出了一些建议和展望。

| Abstract: | Recognize the problem of agro-ecosystem CO_2 sources or sinks from multi-angles helps draft correct agricultural management policies, by cutting down carbon emission and increasing carbon reservation, to help China take initiative in output author; Research state about carbon cycle in farmland and normal observation methods of internal and external were introduced detailed in this essay; Merits and demerits analysis were measured by several routine methods, such as eddy covariance method, static opaque chamber method, static transparent chamber method. The search advances on farmland CO_2 flux estimation in Europe and America were proposed, method and ways to improve the accuracy of carbon exchange measurement in farmland have been raised in this essay; Finally, in accordance with the realities and necessities of agro-ecosystem flux research in China, some suggestions and prospects were put forward. |
