Driven by the “dual carbon” goals, the large-scale mechanized construction of wind and solar power facilities in China’s desert, Gobi, and wasteland areas has caused significant disturbances to the fragile ecological environment. This study proposes soil remediation principles centered on “source control, classified management, adapting to local conditions, and comprehensive management,” developing a multi-level soil management technology system. Systematic restoration of damaged soil functions was achieved through surface structure remodeling (mechanical tillage combined with organic-inorganic composite material backfilling, and construction of windbreak and sand-fixing barriers), salinization control (coordinated underground pipe salt drainage and bioremediation), in-situ passivation of pollutants (using a modified zeolite composite passivator), and vegetation reconstruction (configuration of local pioneer plant communities and irrigation-free planting technology). Post-restoration assessments conducted within demonstrated that the pH recovery rate in the 0–10 cm, 10–30 cm, and 30–50 cm soil layers exceeded 95%, and the recovery rate of organic matter content reached 80–85%. These results verify the effectiveness of the integrated technical solution in improving soil physicochemical properties and rebuilding ecological functions, providing scientific support for the coordinated promotion of new energy construction and ecological protection in arid regions.
