Abstract: In order to deal with the problems of plant invasion, habitat diversity decrease and hybridization penetration, induced probably by plant introduction in greening works, Japanese Society of Revegetation Technology has set up a plant problem committee, and held workshops on countermeasure. And according to the comments or suggestion, the paper is abstracted to discuss the plant species selection suitable to revegetation aiming at the protection of biological diversity，and a proposal is putting forward based on the comprehensive consideration from the seedling supply system up to planning, design, and construction stages of greening work.
