Through remote sensing inversion, the evolution and treatment of saline and alkaline land can be monitored on a large scale in real time. The spectral data and salt content of samples for saline and alkaline land are obtained, and the inversion model is an improvement to the extreme learning machine, which is based on the activation function and the seagull optimization algorithm (SOA). First, the paper proposes the two-hidden-layer extreme learning machine (TELM) based on the hyperparameter activation function and the seagull optimization algorithm (HS-TELM). Then, opposition-based learning (OBL), the Cauchy distribution, and the inverse S-shaped functions (Anti-softsign, Anti-tanh, Anti-sigmoid) are used to improve the SOA, resulting in an improved seagull optimization algorithm (ISOA). At the same time, a series of improved algorithms based on the ISOA and the TELM, including the TELM based on the improved seagull optimization algorithm (ISOA-TELM), the TELM with different hidden layers containing different activation functions (D-TELM) based on the improved seagull optimization algorithm (ISOA-D-TELM), the TELM based on the hyperparameter activation function and the improved seagull optimization algorithm (ISOA-HS-TELM), and the TELM with different hidden nodes containing different activation functions (ND-TELM) based on the improved seagull optimization algorithm (ISOA-ND-TELM), are proposed. The experimental results show that the accuracy of the distribution map of salt content is 2.203 g/kg after adding the spectral correction model, which yields the expected high-precision inversion.
