| 摘 要： | 目前国内外对能量和CO2涡动相关通量的测量误差的谱修正缺乏一致性，导致各测量站之间的资料对比难以进行，给全球尺度资料的合成造成很大困难。因此在强调长期CO2通量测量精度的同时，还应该注重确定对测量误差修正的首选方法和研究重点。该文主要介绍了两种用于修正测量仪器误差的谱方法；二维和三维的气流运动对通量误差的影响；资料处理中的误差；夜间CO2通量的测量问题。

| Abstract: | The lack of unanimous opinion in spectral correction of energy and carbon dioxide eddy covariance flux error caused the difficulties not only in intercomparison of results derived from the different experiments,but also in synthesis data for global models. Two kinds of spectral methods used to correct sensor error were introduced. The influence of two-dimension and triple-dimension air current on CO 2 flux was discussed. Meanwhile, Error encountered in processing data and problems of measurement CO 2 flux in nighttime were investigated. |
