Ecological restoration method for pine wood nematode damaged pine forest

The invention discloses an ecological restoration method for pine wood nematode damaged pine forest. According to the technical route, the masson pine forest is divided into four degeneration types according to habitat conditions, community structures, evolutionary changes and damage conditions. For a scattered pine-deciduous shrub type, sunny shrubs and bamboos and weeds are cleaned, local broad-leaf target tree species seedlings are reserved and cultivated, soil preparation, afforestation and tending are carried out, and target tree species such as schima superba and sweetgum are promoted to update and build new groups. For a scattered pine-evergreen shrub type, sanitation cutting, thinning and cleaning, complementary planting and tending are carried out to promote the regeneration succession of communities. For a pine-sweetgum forest type, the vigor and stability of the forest are improved through sanitation cutting, thinning, complementary planting and cultivation of prepared target trees. For a pine-schi
