Abstract: Result summaries and theoretical sublimation were made on the basis of researches, applications and practices in the field of environmental green remediation in the past two decades. At first, the new insight of "hyper-accumulative or remediation plants also occur in non-polluted areas" was put forward through a large number of practices, and a new method of mutual corroboration for screening out hyperaccumulators or remediation plants between clean areas and polluted areas was constructed and verified, on the basis of having supplemented and perfected the criteria for identifying and determining hyperaccumulators or remediation plants. Moreover, the theory of interaction between plants and environmental media based on the formation and growth of hyperaccumulators or remediation plants and the mechanisms of eco-pattern optimization and comprehensive strengthening of environmental remediation are further proposed, on the basis of having clarified the interaction relationship between hyperaccumulation/remediation plants and soil. This progress has undoubtedly laid a theoretical foundation for further development and extensive practice in this field in the future, and pointed out the direction of future development.

Key words: ecological remediation, green governance, geochemical principle, hyperaccumulation/remediation plant
