水库水气界面温室气体通量监测方法综述

Review of methods for measuring greenhouse gas flux from the air-water interface of reservoirs

  • 摘要: 水库水体中的有机碳,经过水中微生物代谢分解,生成甲烷、二氧化碳等温室气体,通过扩散、气泡等方式,经由水气界面排向大气。目前国外对水库水气界面的温室气体通量监测已经发展了静态箱法、梯度法、倒置漏斗法、TDLAS法以及涡度相关法等。综述了以上监测方法的原理、应用、优缺点及适用范围,从水体、陆地和气候环境方面分析了影响水气界面温室气体排放通量的因素,展望了遥感技术在水库温室气体通量监测中的应用前景,通过遥感技术与水面监测相结合,实现两者的时空互补。对国外开展水库温室气体通量监测的方法进行综述,可为国内水库开展相关监测提供参考。

     

    Abstract: Carbon dioxide (CO2)and methane (CH4)produced during decomposition of organic matter (OM)in reservoirs are emitted from the air-water interface either by diffusion or ebullition.The static-chamber,gradient descent,invert funnel,TDLAS (Tunable Diode Laser Absorption Spectroscopy)and eddy covariance are commonly used methods for measuring CO2 and CH4 fluxes from the air-water interface of reservoirs in abroad.In this study,we review the principle and application of above mentioned methods,their pros and cons,as well as applicability limitations.Factors affecting the emission of greenhouse gases from reservoirs are analyzed from the perspective of water, terrestrial and climatic environment.Prospects of the application of remote sensing technologies for monitoring green-house gas emissions from reservoirs are presented.Using remote sensing technologies and surface measuring methods can be complementary to each other in both time and space.Our study provides a valuable reference for monitoring greenhouse gas emissions from reservoirs in China.
