Abstract: The total area of salinized grasslands in Hulunbuir City is approximately 460 100 hectares, primarily distributed across New Barag West Banner, New Barag East Banner, Prairie Chenbarhu Banner, and Ewenki Autonomous Banner (collectively referred to as the four pastoral banners), accounting for 4.6% of the city′s total grassland area. This salinization diminishes grassland productivity and reduces available land, posing significant constraints on ecological development and the advancement of grassland-based animal husbandry in Hulunbuir City, and furthermore, impacting the ecological security of northern China. In light of this, this review presents a comprehensive review of the grassland resources, climatic conditions, and the current state of salinization within these four pastoral banners and summarizes the underlying causes of grassland salinization and relevant management strategies, aiming to provide a reference for optimizing salinized grassland management strategies and enhancing these degraded grassland resources in Hulunbuir City.

Key words: grassland resources, climatic conditions, grassland salinization, Hulunbuir City, management strategies
