煤田火区温室气体通量测量方法研究进展

为提高煤田火区温室气体通量测量的准确性,科学制定温室气区减排措施,笔者对国内外煤田火区温室气体测量方法进行梳理,对比分析各种测量方法的原理、优缺点和适用范围等,提出测量方法存在的问题及以后的研究方向。研究表明:目前所用的测量方法存在测量精度低、连续性差、假设理想化等缺陷,检测设备的改进应朝着能适应当地地表高温环境并能实现连续监测的方向发展,测量方法应更注重和新技术的结合。

Review on Flux Measurement Methods for Greenhouse Gases in Coalfield Fire Zones

The domestic and foreign greenhouse gas measurement methods are summarized in order to improve the accuracy of greenhouse gas flux measurement in coalfield fire zone and formulate scientifically emission reduction measures for greenhouse gas.The existing problems and future research direction of the measurement methods are put forward via analyzing the principles,advantages,disadvantages and application scope of various methods.Research shows that the current measurement methods still have some defects,such as low measurement accuracy,poor continuity,and idealized hypothesis.The development direction of improving detection equipment should adapt to the local high surface temperature environment and realize continuous monitoring.In addition,more attention should be paid to the combination of measurement methods with new technologies.
