Abstract: The protection, recovery and reconstruction of ecological system in riparian zone have important scientific value and practical meaning. The author reviewed the research progress of the function of ecosystem in riparian zone, summarized the degradation mechanism and ecological remediation both at home and abroad, analyzed the research progress of heavy metal pollution of riparian zone soil and its evaluation methodology. In terms of soil environment and its repair research, the foreign scholars focus on the research of the restoration of degraded riparian ecological system and riparian management of the vegetation buffer zone in recent years, while the research on the theory and practice of the restoration of riparian ecosystems are still weak in our country. In terms of the research of heavy metal pollution in riparian zone soil, riparian zone soil has heavy metal pollution in different degrees both at home and abroad, and it has obvious ecological risk. Current researches concentrate on the degree of heavy metal pollution in soil and the analysis of pollution status; domestic and foreign scholars have not taken environmental factors and the response characteristic of soil organism into account, this lead to an unclear evaluation of possible heavy metal ecological hazard.
