摘　　要：准确测定地表碳通量对评价陆地生态系统碳源、碳汇的区域分布、寻找未知碳汇及预报未来的气候变化趋势意义重大,涡度相关法以其独特的优势成为研究碳通量的标准方法。文中简要回顾了涡度相关技术的发展历程和基本原理,概述了其优缺点,着重总结了碳通量变化规律、环境响应机理及碳收支和测量尺度提升在陆地生态系统碳通量方面的研究成果,并从避免误差、数据处理、模型的应用及数据的空间拓展等方面探讨了今后的研究重点。Precise measurement of land surface carbon budget is of great importance in evaluating carbon source of terrestnal ecosystems and the geographical distribution of the carbon sink,searching for the new carbon sink and forecasting the trend of global climate change. The eddy covarianc becomes the standard way of researching carbon budget for its unique advantage. This paper briefly reviewed the development process and basic principles,outlined advantages and disadvantages of eddy covarianc technology,while summaried the research results of eddy covarianc technology applied in carbon budget of terrestrial ecosystem in terms of adiabatic relationship of carbon budget, environment response mechanism, carbon budget and scale promotion. The future key projects about the avoiding deviation,data processing,application of the mathematical modeling and the expansion of representative space scale were discussed in this paper.
