AI Technical Summary
Existing technologies for ecological restoration of slopes in the dry-hot valley area of the upper reaches of the Jinsha River suffer from poor adaptability and low survival rate of introduced plant species, as well as a simple plant community structure and insufficient diversity, making it difficult to form a stable self-sustaining vegetation system. Furthermore, native seeds have a low germination rate and there is a lack of multi-species collaborative cultivation methods.
Through natural slope soil surveys, local drought- and heat-resistant native plants were selected as suitable dominant plant varieties. These plants underwent bark breaking, disinfection, dormancy breaking, soaking, and moisturizing treatments to promote germination. They were then mixed with fast-growing foreign varieties to form a near-natural diversity of seed configurations. After hydroseeding, artificial maintenance was carried out until a near-natural ecological vegetation system was formed.
It enables rapid revegetation of slopes, prevents soil erosion, and allows introduced species to naturally evolve into local vegetation, forming a long-term stable ecosystem. It has technical advantages that cannot be matched by single-species methods.
