Land restoration is the process of ecological restoration of a site to a natural landscape and habitat, safe for humans, wildlife, and plant communities. Ecological destruction is usually the consequence of pollution, deforestation, salination or natural disasters. Land restoration is not the same as land reclamation, where existing ecosystems are altered or destroyed to give way for cultivation or construction. Land restoration can enhance the supply of valuable ecosystem services that benefit people.

The restoration process is predicted in time series by combining the autoregressive integral sliding average model, which can quantitatively evaluate the restoration completion time and assist in scientific management and decision-making. The overall solution realizes multi-dimensional comprehensive evaluation and dynamic closed-loop optimization of the ecological restoration effect of saline-alkali water bodies, significantly enhancing the pertinence, real-time nature and sustainability of ecological restoration, and providing scientific and efficient technical support for saline-alkali land restoration.
