The invention relates to the technical field of water and
soil conservation monitoring, and discloses a
remote sensing image-based water and
soil conservation monitoring method, which comprises the following steps of: 1, integrating optical,
infrared and
microwave remote sensing data, and constructing a soil information atlas; step 2, capturing
soil humidity change in each season by using long-time-sequence data according to the soil information, and determining the influence of rainfall,
snow melting and
evaporation on the
reflectivity; step 3, training data of each
wave band through a deep neural network according to the influence information of the
reflectivity; through an
adaptive learning algorithm and a
model parameter regular updating mechanism, the problem that in the prior art, characteristic spectrums of wet soil,
vegetation and bare soil are overlapped due to seasonal changes is effectively solved, after the seasonal modulation factors are introduced, the
system can accurately capture influences of natural factors such as rainfall,
snow melting and
evaporation on the soil
reflectivity, and the soil reflectivity is improved. And
model parameters are adaptively adjusted, so that the interference of reflectivity fluctuation on a monitoring result in wet and drought states is eliminated, and the stability of long-term monitoring is ensured.
