摘　　要：目前涡动相关法被认为是国内外测定CO2、水热通量的最可靠方法。国外应用此方法解决了均匀下垫面假设下森林和农田等生态系统的CO2、水热通量的计算问题,目前致力于非理想下垫面(真实地形)的CO2、水热通量的计算。而国内应用涡动相关技术起步较晚,用此方法测定水热通量已有一定的知识积累,但测定CO2通量还处于资料收集阶段。我国自然生态系统、环境外交和社会经济可持续发展都要求精确查明我国CO2的时空变化特征和动力学机制,这应是今后研究的重点,并提出了应用该方法存在的主要问题及可能的解决方法,指出值得深入研究的领域。At present eddy-covariance technique（ECT） is considered one of the most reliable methods in measuring CO2 ,heat and moisture fluxes. In terms of the method foreign countries have solved the calculation problems of CO2 or heat and moisture fluxes of forest and farmland ecosystems under the assumption of homogeneous underlying surface, at moment are making efforts to calculate the fluxes of non-ideal underlying surface （real terrain）. Application of the ECT in our country is later. Some knowledge on measuring heat and moisture fluxes by using the ECT has been accumulated,but measuring CO2 is still in the stage of collecting data. Under the demand of our country＇s natural ecosystem, environmental diplomacy and the sustainable development of social economy, the future emphases should be placed on accurately measuring the temporal and spatial variations of CO2 and revealing its dynamic mechanism. The problems and possible solutions to the eddy-covariance are presented and the deserved research field is also put forward in this paper.
