It is shown from the study results that when the CDOM concentration ρ≥62.5mg/L, there was only a peak in the EEMS spectrograms, the excitation and emission wavelengths moved blue with decreasing CDOM concentration, and the move in wavelength and the change in CDOM concentration were well correlated; when ρ≤52.5mg/L, there were 3 peaks in the EEMS spectrograms, and the EEMS spectral shapes were basically invariant when the CDOM concentration changed.

结果表明：当CDOM质量浓度ρ≥62.5mg/L时，其EEMS均为单一峰，随着质量浓度降低，激发和发射波长向短波长方向移动，这种波长移动变化与质量浓度的变化呈良好的线性相关关系；当ρ≤52.5mg/L时，其三维荧光光谱显示3个峰。质量浓度在此范围内变化时，EEMS谱形基本不变。

When the CDOM concentration ρ≥150mg/L, the excitation and emission wavelengths in the SFS spectrograms moved blue with decreasing CDOM concentration, and the SFS spectral shapes also changed; when ρ50mg/L, the excitation and smission wavelegths in the SFS spectrograms didn't move, and the SFS spectral shapes were invariant, but the fluorescence intensity decreased with decreasing CDOM concentration.

不同质量浓度CDOM水溶液的SFS显示，当质量浓度ρ≥150mg/L时，随着质量浓度降低，激发和发射波长也向短波长方向移动，其谱形也发生变化；当ρ50mg/L时，激发和发射波长不发生漂移，谱形不变，荧光强度随质量浓度降低而降低。
