High-elevation and cold regions have harsh natural conditions with low temperatures and intense ultraviolet radiation; which impede plant growth and maintenance. Therefore; soil and water conservation vegetation restoration models are of great significance. In this study; a site condition analysis was performed based on three main limiting factors; including climatic and meteorological; soil; and topographic and geomorphological factors; providing a basis for vegetation restoration. The study area was divided into different site types. After investigating the situation of nurseries distributed in places such as Tibet; Qinghai; and Sichuan; trees; shrubs; and grasses with ecological characteristics similar to those of the local vegetation; including strong stress resistance; good soil and water conservation benefits; and well-established artificial cultivation practices; were selected as alternative vegetation for late-stage planting of indigenous tree species. Combining the results of site condition analysis and site type classification; the configuration of trees; and grasses for different off-site condition types and the corresponding greening methods are discussed; providing a scientific reference for ecological restoration in high-elevation and low-temperature regions. © 2024 by the authors;
