This invention discloses a smart ecosystem for desert soil degradation that synergizes photovoltaic desertification control with the resource utilization of concentrated brine in agriculture. In this invention, industrial solid waste is transformed into multifunctional ecological restoration materials, constructing a stable aggregate structure for desertified soil. Simultaneously, the scientific configuration of salt-tolerant vegetation rapidly establishes a vegetation community adapted to the local environment, effectively curbing wind and sand erosion. The shading effect of the photovoltaic array not only reduces surface water evaporation but also creates a suitable microclimate for vegetation growth, gradually forming a virtuous cycle of soil-vegetation-microorganisms. This fundamentally reverses the desertification process, improves the regional ecological environment, and achieves efficient recycling of various resources through the construction of a complete closed-loop synergistic system. Furthermore, the stable electricity provided by the photovoltaic system not only meets its own operational needs but also drives seawater desalination and concentrated brine separation treatment, transforming concentrated brine into valuable resources for vegetation irrigation and soil improvement, avoiding resource waste and secondary pollution.
