通过室内实验，研究了悬浮颗粒物（SPM）浓度对水体光谱反射率的影响。通过曲面拟合分析，得到了波长、反射率和水体中SPM浓度之间的经验关系。结果表明，随着水体中悬浮颗粒物浓度的增加，光谱波长对反射率的影响呈线性关系，反射率与水体中悬浮颗粒物浓度呈二次曲线关系。高光谱遥感技术有望在水体悬浮颗粒物浓度估算中发挥重要作用。
A laboratory experiment was designed to collect the spectral reflectance of water containing suspended particulate matter (SPM) in terms of its concentration. By performing surface-fitting analysis, an empirical relationship among the wavelength, reflectance, and concentration of SPM in water was obtained. The results showed that a linear effect of the spectral wavelength on spectral reflectance with increasing concentration of SPM in water, and the relationship between the reflectance and concentration of SPM in water is quadratic. Hyperspectral remote sensing is expected to play an important role in estimating the concentration of SPM in water.
