Abstract:This paper analyzes the problem of soil and water resource degradation in salinized canals, elaborates from multiple aspects including engineering protection, soil improvement, and vegetation reconstruction, and proposes soil and water conservation schemes such as canal seepage prevention and salt control, foreign soil replacement, and underdrain salt drainage, as well as ecological restoration technology strategies including microbial desalination, biochar improvement, and salt-tolerant plant configuration. It discusses various measures: adopting a composite anti-seepage structure to cut off the salt migration path, using foreign soil replacement to reshape the soil environment, combining underdrain salt drainage to optimize the soil-water cycle, applying microbial and biochar technologies to improve soil physical and chemical properties, and using salt-tolerant plants and ecological bag slope protection to build an ecological barrier. Practice has verified that the integrated application of these technologies can inhibit soil salinization, enhance slope stability, and restore ecosystem functions, which can provide a reference for ecological management in similar areas.
