This invention discloses a pretreatment method for ecological prevention and coordinated emergency response to colluvial deposits and landslide dams on riverbanks. It utilizes mature trees planted vertically at the slope toe, intersecting with horizontally planted mature trees on the slope surface to form a framework of living trees. Simultaneously, waterproof soil bags filled with rock and soil fragments are used to construct soil pillars or walls, providing support for the horizontally planted mature trees. The framework of living trees and the soil pillars or walls together form a retaining structure to prevent potential landslide impacts. The spaces between the soil pillars or walls create a drainage channel for the landslide dam, collectively providing ecological prevention and coordinated emergency response to colluvial deposits and landslide dams on riverbanks. This invention can replace the post-treatment technology of emergency excavation of spillways after landslide dam formation. By pre-constructing the drainage channel before the dam forms, it achieves ecological protection of riverbanks, reduces the risk of landslide damming, and is easy to construct.
