The invention discloses a method and
system for inverting the concentration of
suspended solids in a complex
water body through
remote sensing, and belongs to the technical field of ecological environments. Comprising the following steps: integrating a
remote sensing image and measured data to obtain a synchronous sampling
point pair; analyzing the backscattering coefficient of the particulate matters, and determining the backscattering coefficient of the optimal
wavelength position for reflecting the total
suspended matter concentration through an iteration method; analyzing the particulate matter absorption coefficient, and determining the absorption coefficient of the optimal
wavelength position for reflecting the total
suspended matter concentration through an iteration method; according to the proportional relation between
inorganic particles and organic particles in the
water body, determining the weight of the absorption and
scattering coefficient for estimating the total
suspended matter concentration; and constructing a
remote sensing estimation model of the total suspended matter concentration in the complex
water body and applying the model to a remote sensing image. According to the method, the difference of the organic particulate matters and the inorganic particulate matters in the aspects of absorption and scattering characteristics is considered, and the method is suitable for a water body mainly containing
algae, a water body mainly containing non-
algae and a complex water body environment in which the water bodies and the non-
algae are mixed, and has relatively high adaptability and accuracy.
