Abstract

Technical Field
[0001] This invention relates to a prefabricated fish-scale pit revegetation system and construction method, which is mainly applicable to ecological revegetation construction. Background Technology
[0002] Afforestation and greening are perpetual themes in forestry development, and ensuring the survival rate of afforestation is a crucial indicator of the success or failure of afforestation and greening efforts. Fish-scale pit land preparation for afforestation is particularly suitable for sunny, steep slopes with severe soil erosion, thin soil layers, exposed soil and rocks, and persistently low soil moisture. In such areas, general afforestation methods are unlikely to be successful. These areas urgently need forest restoration to quickly provide multifaceted protective functions, while also achieving the goals of greening, beautification, and timber production. Therefore, adopting special afforestation land preparation methods is absolutely necessary.
